Dog being held by vet (caption: Benefits Of Spaying And Neutering Dogs)The topic of spaying and neutering is most often brought up by dog owners; however, it is a subject that should be addressed by all pet owners. There are many benefits of spaying and neutering, including improved health outlook, improved temperament, a declining homeless pet population and a reduction in the expense associated with breeding.

What Is Spaying?

Spaying is the practice of sterilizing female animals by removing the reproductive organs, including the ovaries and uterus. Spaying typically occurs between 4 and 6 months, but it can happen for older pets as well as long as they are in good health.

A female dog that is pregnant or in heat can be spayed. Spaying during pregnancy will terminate the pregnancy and can be performed until just a few days before delivery, although this is not recommended.

A spayed female typically takes longer to recover than a neutered male but is considered sterile immediately following her surgery.

What Is Neutering?

Neutering (also referred to as an orchiectomy or castration) is the practice of sterilizing male animals by removing the testes. The penis is not operated on during this procedure, and the outer sac that once held the testes is left in place.

Neutering is usually performed between the ages of 8 weeks and 6 months; however, it can be performed on older animals as well as long as an animal is in overall good health.

Male dogs generally recover much more quickly following neutering than females do from spaying since spaying is much more invasive and results in a larger incision.

A neutered male is not considered sterile immediately following his surgery. On average, it can take around 2 weeks or as much as 6 weeks for a neutered male to be considered sterile.

It is important to keep a neutered male away from any females in heat for around 6 weeks to ensure that pregnancy will not result from the encounter.

How Much Does Spaying & Neutering Cost?

The cost of spaying and neutering depends on a wide range of factors including the overall health of the animal, the size and weight of the animal, geographic location and whether the surgery is spaying or neutering. A lot of pet owners choose to have their regular veterinarian perform their animal’s spaying or neutering surgery.

The price range for spaying and neutering from a regular veterinarian ranges so significantly that there is no way to portray it accurately; however, there are many clinics that provide affordable spaying and neutering for between $40 to $150 per pet. Spaying and neutering can also be made more affordable by visiting your local animal shelter where the surgery can be performed at a lower cost than it is at most veterinarians or by purchasing a wellness plan, which will cover a portion of the procedure.

Is It Worth Paying More?

The first priority of pet owners should be providing a safe spaying and neutering experience for their pet. This type of experience is provided by all licensed veterinarians regardless of whether they work at a private clinic, a low-cost clinic or at the ASPCA or Humane Society.

With that said, there are benefits to going with a private veterinarian clinic for your dog’s spaying or neutering surgery. Using a private vet will allow you to build a relationship with a vet whom you and your dog will have a lifelong relationship.

There are also smaller considerations to take into account, such as the fact that many lower-cost clinics utilize glue to close spaying incisions rather than stitches. Glue will hold together an incision, but it can result in skin reactions, slower healing and reopening of the incision (although this can happen when using stitches as well.) While the choice between stitches and glue is a personal one for the veterinarian doing the surgery, lower budget clinics opt to use glue over stitches more often.

What Are The Benefits?

There are many reasons as to why pet owners should spay and neuter their pets.

Fewer Homeless Pets

This reduction would not only result in fewer animals living on the streets and being euthanized, but it would also increase the available space in shelters for animals that may otherwise be thrust into homelessness.

Decreased Risk For Cancer

Neutered male dogs experience is a reduced risk for testicular cancer. Spayed females have a reduced risk for mammary, uterine, ovarian and cervical tumors.

Other Beneficial Health Effects

Neutered male dogs also experience a reduction in non-cancerous prostate disorders, a reduction in perineal fistulas and it is also believed a reduced risk for diabetes.

Female dogs that are spayed also experience a significant reduction in pyometra (a uterine infection) and perineal fistulas.

Less Breed Dilution

Another reason to spay and neuter your pet is due to their love of the breed. Most of us who have owned a pet like to think that our pet is the “best” there is; however, it takes much more than a personal opinion to make a dog that is a benefit to its breed.

Each specific breed of dog has particular standards set out by the American Kennel Club determining what makes a dog the best of its breed. These standards outline height, color, markings, health, clearance of hips, eyes, elbows and heart health.

All of these characteristics come together to make a dog healthy and help lead to an overall better breed. Breeding dogs that don’t have “clearance” from breeding organizations can lead to breed dilution and a much weaker dog with various inbred health conditions.

By spaying and neutering dogs that are not the best of the breed, we can ensure that healthy breeding lines live on and dogs experience fewer genetic health concerns.

Improvement In Behavior

Behavior can be affected by whether or not you spay or neuter your pet. One of the most obvious differences between a spayed or neutered pet and an unaltered pet is the need to “roam.”

Male pets will go to great lengths to get to a female that is in heat; this includes behavior such as tunneling under fences and leaping over gates. The scent of a female in heat can carry for considerable distances making it extremely difficult to contain a male pet that smells a female in heat.

Another consideration is the effect that hormone release has on the behavior of an animal. Males, in particular, can become extremely dominant or bullheaded as a result of surges in testosterone. These pets can be extremely difficult to control and train.

Hormones also play a role in instincts, such as marking behavior and shows of dominance and aggression. The majority of dog bites involve dogs that have not been fixed. Spaying and neutering can reduce these behaviors and make animals easier to manage, which can result in fewer frustrations for the animal.

Note: Some recent studies show that some intact males show less aggressive behavior than “fixed” dogs, especially when neutered at a young age. There have also been rare reports that female dogs who are spayed become more active, aggressive and/or anxious.

Less Mess

Mating is a messy business. Not only do males release ejaculate, but females experience menstruation.

The heat cycle during which the female bleeds can begin as early as 6 months old. For dogs, this cycle occurs approximately twice a year and lasts for 3 weeks.

In cats, the heat cycle occurs every 3 to 4 weeks from spring until fall. During heat cycles, females need to wear protective garments which must be changed frequently; this prevents the spotting of blood on furniture and around the home.

Females in heat must be kept away from all males; this means the female must not be allowed unsupervised access to anywhere she could potentially be mounted by a male. The act of mating can occur in seconds and result in an unwanted pregnancy.

Cost Of Pregnancy

Many people think that they would like their dog to have babies once in their lifetime; these people rarely understand the cost of both pregnancy and raising young.

Litter of puppiesThe pregnant female requires supplementation with vitamins in addition to a higher quality dog food. Regular veterinarian check-ups are a must to ensure the health of offspring as well as the mother to be. All of these expenses occur before the youngsters are even born.

The birthing process is another potentially expensive experience. Several conditions can arise that require veterinary intervention, which can be costly; it is also possible for the birthing female to experience complications that cost her her life.

Assuming the mother and babies make it out of delivery, there is then the added cost of raising young. The nursing mother requires premium food, and her babies require both regular medical checkups and preventative medication.

After raising babies to approximately 8 weeks, they must all be found safe and responsible homes. Just because a pet owner believes that their pet is the best “____” ever, does not guarantee that everyone else does too, it is possible that all offspring may not find a home.

As a responsible pet owner, it is up to you to raise the young until such a home can be found. Many pet owners shirk this responsibility, and if a home cannot be found for offspring, they are dumped in a local shelter, feeding a vicious cycle.

Excuses For Not Spaying And Neutering

A German Shepherd being spayedPet owners have many excuses for why they don’t want to “desex” their animal.

  • I want another dog just like Fido – We are not duplicates of our parents and the same goes for our dogs. Each living thing is unique.
  • Spaying and neutering will make my pet fat – Fixing your dog can reduce their level of activity and cause hormonal changes, but poor diet and exercise is the cause of their weight problem.
  • We could become breeders and make money – Breeding is done for the love of the breed and isn’t always a profitable business. There are many fees associated with feeding that cause breeders to lose money.
  • My pet will change after they get spayed or neutered – Pets typically change for they better. They become less aggressive and are less hardheaded.
  • My pet deserves the chance to be a parent – We tend to put human emotions and desires on our animals. Being a parent as a human is different from being a parent as an animal. Animals care for their young for a set period and it doesn’t consist of enrichment activities as it does for humans.
  • What if the surgery goes wrong – This is a valid concern, but rarely does anything go wrong. These are routine surgeries, but there are instances where a dog reacts to anesthesia.
  • We always find homes for our puppies – The people who take in the puppies you have are people who could have saved a dog from a local shelter or rescue group. This means there is one less home and one less second chance for a dog in need.
  • My dog is always contained – Dogs can escape back yards and other dogs can break into your back yard. Dogs get lost and run away every day.
  • It’s not natural to spay or neuter dogs – It’s also not natural to own dogs as possessions, but we domesticated them.
  • I couldn’t look my dog in the eye if I cut off his boys – Could you look him in the eye if he developed testicular cancer that you could’ve prevented?
  • My dog will feel less like a man – Dogs do not have a concept of sexual identity, neutering them will not cause an identity crisis for them.
  • It’s healthier for female dogs to have a litter before being spayed – There is no medical research supporting this.
  • Spaying and neutering is too expensive – Many vet clinics and shelters offer discount spay and neuter services to help families with financial constraints to provide for their pet.
  • My children should experience the miracle of birth – There are other ways to educate your children than them witnessing it first-hand. Show them a video, share an article with them, etc.
  • My dog is a purebred – If you aren’t a certified breeder, you have no place breeding your dog.
  • Spaying and neutering will make my dog less protective – A dog will not lose their natural instinct to protect their family.
  • My dog should experience a heat cycle before being spayed – It is riskier for a dog to go through a heat cycle than for them to undergo spaying surgery before heat.


These statistics about euthanasia in animal shelters and spaying/neutering are shocking.

  • Every year approximately 5-9 million shelter animals are euthanized.
  • 50% of dogs and 70% of cats in shelters are euthanized due to lack of adopters.
  • Every 6 seconds in the United States alone an animal is euthanized.
  • Approximately 25% of shelter pets are purebred and have “papers” to prove it.
  • Only ten percent of animals that find their way to local shelters have been spayed or neutered.
  • 75% of owned pets are spayed or neutered. While this is a good start, it is not nearly enough considering the number of pet dogs and cats in the nation.

What The Spaying & Neutering Process Is Really  Like For Your Dog

Humans can never be truly sure what a dog feels, but here is a glimpse into the procedure based on vet knowledge and research.

No matter your dog’s sex, the first thing that will happen is the dog is placed under general anesthesia. This usually involves a quick injection, which vets are trained to perform while keeping the dog calm. All the dog experiences after that is sleep, and no pain, much like a human in surgery.

A tube is fed into the dog’s airway, and his/her breathing is ventilated throughout the procedure and heart rate is monitored. This is where it begins to vary for males and females

Your Male Dog’s Experience Being Neutered

After anesthesia is administered, breathing is ventilated and vitals are monitored, the fur in front of the scrotum is clipped or shaved, and the skin is sterilized using a topical antiseptic wash.

A small incision is made in that location using sterile surgical tools. For puppies with both testicles descended, the next step is the clipping of the vas deferens and the removal of the testicles, which takes 10 to 20 minutes. (An undescended testicle, while rare, will take a bit longer as it presents a minor complication to remove a testicle from the abdomen.) The vas deferens and the blood supply to the area are tied off, and the small incision is closed with surgical glue, staples, or in rare cases, sutures.

Post-Neuter Care

Puggle puppyThe dog wakes up without pain or numbness when the anesthesia wears off and is often able to go home that day. He may be sore, and your vet will supply minor pain medication as well as instructions for how to check for infection. Dogs can eat and drink normally when they get home, but require gentle, monitored walking and should refrain from jogging or rough playing with other dogs or people who might accidentally worsen the surgery wound.

If your dog looks like he is going to lick his stitches, a cone will be placed around his neck until the wound heals. Although this might be annoying to him, it is important that he does not aggravate the sensitive spot of the incision until after the stitches are removed or the wound is fully closed up. The wound should be healed after about one week, and the dog can resume his usual antics.

Your Female Dog’s Experience Being Spayed

After anesthesia is administered, breathing is ventilated and vitals are monitored, the skin on the abdomen is shaved or clipped and treated with an antiseptic. A small abdominal incision is made, and the uterus and ovaries are removed, and the blood supply sealed off.

The procedure takes about 15 to 30 minutes, or more if your dog is overweight. The wound is sealed with surgical glue, staples or sutures. The stitches are in 2 to 3 layers so if one layer starts coming undone, the other layers remain intact.

If the surgery is performed during estrus (while the dog is in heat), expect it to take longer, require more supplies and be a little riskier. The medication used before, during and after surgery may vary as well. These adjustments often lead to a more expensive vet bill.

Post-Spay Care

The surgery is deeper into the abdomen than neutering, but dogs heal just as quickly after being spayed. The dog wakes up, and will not be sore immediately. Vets usually prescribe minor pain medication for the days after the surgery, and once again you are required to check for infection. The dog will not be able to eat normally until the day after returning home, to give the wound time to heal enough before pressure is put on it from a full stomach.

Nausea is a common symptom that may make her not want to eat; home remedies may be recommended for this or in some cases, medication will be prescribed. The vet will instruct you on how to feed and water her before then. Since female spays are more likely to have sutures or staples, those require a return visit to the vet’s office within 10 to 14 days for removal.

It is often reported that after spaying your dog, her metabolism slows, so for adults, this may require lower calorie food or a special diet. Like with a neuter, the first week after a return home will be especially gentle for your dog, but after a week she can resume all her usually playful activities.

Can I Use A Discount Spay And Neuter Clinic?

The cost of spaying and neutering pets is often enough to turn a pet owner away from following through with the process. Fortunately, most communities offer discount spay and neuter clinics to help these pet owners afford this important procedure.

The ASPCA has a listing of spay and neuter programs that are local to any area within the United States. Spay and neuter programs are agencies that provide assistance or referrals to discount professionals who can perform the surgery.

Most dog owners become nervous when they hear the term “discount” when it pertains to something like surgery for their furry family member. In the majority of instances, these spay and neuter clinics are sponsored or held at local SPCA shelters and humane societies. These agencies provide this discounted service because they are the ones who will have to pay for the pet overpopulation if pets are not spayed and neutered.

How Do Spay And Neuter Clinics Work?

Spay and neuter clinics work by asking clients to call and make surgery appointments for their pets. Making surgery appointments is just like making any other veterinary appointment. Generally, these services will ask pet owners to call or submit forms online to request spay and neuter appointments.

Who Performs The Discount Surgeries?

Some people are under the impression that because the service is a discounted service, that poor quality or non-licensed or veterinary students will be permitted to conduct sterilization surgery.

This assumption is simply not true. Sterilization clinics employ only licensed veterinarians not only because it is not ethical to do otherwise, but also because of the potential for other needs while a pet is in surgery.

What Is The Cost Of Discounted Surgery?

Dog in fenced yardDiscount spay and neuter clinics vary in their cost based on a variety of factors. The base fee for sterilization surgery is determined by the area in which the client lives. For example, Furry Friends Community Spay Clinic in Des Moines, Iowa charges $75-$95 for a female dog (depending on dog’s weight), $55-$75 for a male dog (depending on dog’s weight), $50 for a female cat and $40 for a male cat.

Clinics may also add a fee of $15 to $40 for pets that are in heat, pregnant or obese at the time of their sterilization.

What Is Included In The Cost?

As with the question above, what is included in the price of spay and neuter surgery at a discount clinic varies depending upon the clinic. Items may include the sterilization process, a 1-year rabies vaccination, distemper and any other core vaccinations and a pain relief injection for the surgical procedure.

Add on services are also offered based on the individual needs of a client and these can include: additional pain relief medication for recovery, microchipping, heartworm testing, heartworm prevention, flea and tick prevention (applied at the hospital or provided to take home,) Feline Leukemia testing, Feline leukemia vaccination, canine kennel cough vaccination, cone e-collars and cardboard carriers.

Is A Discount Clinic As Good As My Regular Vet?

This question is asked so many times by dog owners because naturally, they care about their dog’s well-being. As already discussed, all discount spay and neuter clinics utilize licensed vets to perform their surgeries. You will notice a difference between the vet that you are used to and any other vet because they are different doctors with different bedside manners; however, both will be professionally trained.

A discount clinic may be more rushed than your vet’s clinic in performing your dog’s sterilization; however, this doesn’t indicate that your dog’s procedure will be rushed. As with your regular vet, these clinics require appointments and schedule only as many patients as they can capably treat within a day.

Do Spay & Neuter Clinics Use Cheap Materials?

This is an unusual question, but it has been asked before particularly by those who have had a dog spayed at a veterinarian clinic that utilizes stitches and a spay and neuter clinic that utilizes surgical glue to close incisions.

The difference between these two methods is particularly noticeable if you are used to one method over the other; however, both are approved methods of wound closure. Depending upon the clinic that performs your pets spay or neuter surgery there is a possibility that the vet will prefer stitches or glue to close an incision. This preference is simply that, a preference of the vet.

Importance Of Supporting Spay & Neuter Clinics

Even if you choose not to utilize spay and neuter clinics, you can still support local clinics by making donations of supplies or monetary donations. These donations go into allowing clinics to provide discounted sterilization surgeries to prevent pet overpopulation.

The higher the population of homeless pets, the larger the stray pet population which increases the risk of disease among feral animals as well as increases the financial strain put on locally-owned animal shelters and animal control centers.

If you have a dog that is not spayed or neutered yet, you may want to consider getting a pet wellness plan for them. Many wellness plans cover a portion of the expense associated with “fixing” a dog in addition to many other things including vaccinations, microchipping, annual exams, teeth cleanings, flea, tick and heartworm treatments and more.

Good article but a recent study with over 9,000 dogs by the University of Pennsylvania (published in Psychology Today) experienced a GREATER amount of aggression and fear in neutered dogs. Females spayed at less than 1 year old also showed greater signs of aggression.

The study found that there are just 4 benefits of neutering and none to do with personality related behaviours.
1-Neutered dogs were less likely to leave urine mark indoors.
2-Neutered dogs were less likely to howl when left alone.
2-Neutered dogs, when off-leash, were also more likely to return when called.
4-Neutered dogs, tended to reliably fetch tossed items.
That’s it for the positive effects of neutering.

Many neutered dogs will aggressively go after intact males. This could be a reason to neuter if visiting dog runs/parks often.

Neutering Causes Behavior Problems In Male Dogs
Are There Behavior Changes When Dogs Are Spayed Or Neutered?

Skyler Williams
I had no idea that spaying and neutering your pets could reduce the risk of certain cancers in them. A cat appeared on my doorstep last night and I wasn’t sure what to do about it. After reading this article, I think I’m going to keep it and definitely get it spayed.
Amanda Smith
Note: Some recent studies show that some intact males show less aggressive behavior than “fixed” dogs, especially when neutered at a young age. There have also been rare reports that female dogs who are spayed become more active, aggressive and/or anxious.
Neutering an anxious dog of any sex is the WORST thing you can do to that dog as all it does is make the anxiety worse as the hormones used to help counteract the nervousness are the sex hormones, so remove them & you add to the problem.
What do you call neutering young? No dog should be neutered until they are a minimum of 6-8 months old. I know it’s common practice in America to neuter from 6 weeks of age but this is tantamount to abuse & it has been proven that this is what is causing the overwhelmingly massive wave of joint disease in dogs that has been seen for years. Bones need the sex hormones to know when to close the growth plates, if that hormone is not present or not enough of the hormone is circulating the body, then the growth plates close at differing rates causing such diseases as Hip & Elbow Dysplasia, bowed legs from the 2 bones in the front legs growing (& the growth plates closing) at different rates, etc. etc. etc.
I think it is so important that you clarified that making surgery appointments is just like making any other appointments. We adopted my cat about a year ago, and she has been the nicest indoor cat ever since. However, we are downsizing and we want to help her become an indoor-outdoor cat, but for that, we will have to make sure she does not get pregnant, so we are thinking about calling a vet nearby to see what our options are. Thank you for this article, it helped me ease some of my fears and made me take another step in the right direction.
If your dog doesn’t have a life partner then why leave them intact? Dogs are known to roam for a partner and would you really risk your dog/bitch getting pregnant by accident whilst out walking?
No, neutering isn’t going to change anything only unnecessary pregnancy. Be responsible dog owners and neuter your pet.
For some actual science behind the objections raised by some, to some of the info in the article, go here.
There is a lot of recent data on the health (and some behavioural) benefits of NOT neutering, for male dogs in particular. It’s is true to say that dlfemale dogs who are spayed get less mammary cancer. It is kind of redundant to say male dogs who are neutered get less testicular cancer–that’s like saying leg amputees get less leg cancer. Further, testicular cancer is usually very easy to see developing and affected testicle are easily removed if that occurs.
There is also quite a bit of newer evidence that anxiety, and aggression related to anxiety(possibly the largest category of aggressive dog, in my reasonably educated view) , may be greater in neutered male dogs.
Roaming/escaping behaviour does seem likely to reduce, so that will depend on how big a problem that is for an individual owner and dog.
My male Kelpie cross is 3 and un-neutered. He’s the calmest, most grounded dog I’ve ever owned. We train several times a week, and he has generally superb obedience and concentration. I would say the biggest problem we face is that un-neutered males seem to randomly take objection to him. I don’t know, but am assuming this is partly to do with his scent being different, possibly 1) an instinctual reaction to the extra testosterone, and 2) to do with unneutered dogs being unusual these days, so it’s an unfamiliar experience and (ironically) raises anxiety even higher. Not sure–all I know is that contrary to all expectation, we’ve had a worse time with neutered males, than unneutered, so far! I don’t want him to get proactive about fighting (as in, he’s had to defend himself a couple times, and I don’t want him to start to go on the offensive-ever-especially since if s*** goes down, it’s the un-neutered male that cops most of the blame regardless of circumstances, I find) , so I am very planned and choosy about where we go, and who he socialises with, which I’ll admit is a bit of a pain.
also very ironic is the fact that he’s so extremely laid back that several trainers have strongly suggested he would make a great therapy or assistance dog- but I can only get certification if I get him neutered. Which for all of the above reasons, I’m reluctant to do! Gah:S
This article is WAY OUT OF DATE…lol…research shows FAR MORE benefits keeping them in tact. And spaying/neutering dogs will not prevent pet overpopulation (although it can contribute to the problem). Irresponsible owners will, period.
This article is opinionated and out of date. Recent results from research funded by the AKC Canine Health Foundation have the potential to significantly impact recommendations for spaying and neutering dogs “prior to maturity”. Read the landmark research findings of Dr Benjamin Hart, UC Davis. For years the veterinary community has been aware that the early spay & neuter may impact orthopedic health in dogs.
To spay, neuter and castrate all mean the same thing, regardless of gender. They mean to remove the gonads (ovaries and testes). So we only need one word because the words are not gender specific, and they do not include removal of the uterus. Removal of the uterus is called a hysterectomy. If you remove ovaries and uterus that is an ovariohysterectomy. Removal of just the fallopian tubes is called a salpingectomy. Consult with a physician or veterinarian first if you are going to write scientific medical articles so you get the terminology correct.
Iris Lacy
There are numerous benefits for waiting to spay neuter until after maturity. It’s understood for shelter populations that this be done earlier.
Amazing. It seems like humans fit the same
above categoried. We also live unnatural lives that attribute greatly to the population growth problem. So, when can we spay/neuter/euthanize them? This is extremely hypocritical.

It seems there is a chance for complications with or without fixing them? Incidences for cancers vs. hip dysplasia, overtaxed adrenal glands, decreased metabolism, etc. I find this article very biased and I personally feel it is wrong to subject an animal to that. It’s about as great a farce on health as removing foreskins which barely has any health benefits whatsoever. I would also find it ideal to keep every edge I can get to maintain their health and weight which the sexual organs contribute, too. Not just exercise alone. Although, I do agree it helps in helping the homeless population, I think you should better inform people of the otherwise of the fence. Spaying/neutering feels like an extreme and dated practice that typically older generations go through to remedy problems, not grow up dealing with and not properly developing. It’s an archaeic practice people just go along with when a simple vasectomy or tube clipping would be sufficient. At least, to allow the pet the natural hormone source that they have evolved to actually require for proper health growing up.

It’s called “responsibility” and obviously you are opposed to it. . So just don’t be a pet owner and you don’t have to worry about it
It’s good to know that spaying and neutering your pet is an important part of having them be domesticated. I agree that domesticating animals has changed the way we need to do things. It’s also good to know that you can prevent certain types of cancer from developing by doing this, like you said.
Louise McNally
This article is blatantly untrue. All the research shows that animals DO change for the worse after spaying or neutering. Dogs become more aggressive, not less. All the information is out there, so it’s totally unacceptable to spout these lies. In Norway it’s illegal to spay or neuter a dog unless there’s a pressing medical need.
Peggy Found
You are Wong. We had our dog spayed and she did not become aggressive. Our children have had several dogs and all were spayed and none were aggressive.
The anecdotal example of your dog does not make this commenter wrong. The facts are out there. I’d refer you to studies dive on over 15,000 dogs referred to in this article.
Louise: you are right. From a health perspective the best time to neuter a male is NEVER. The idiotic reasons for neutering mentioned in this article are infuriating. A lot of these so called ‘problems’ that are supposedly ‘fixed’ by neutering a male are fixed by responsible dog ownership. Most of the reasons mentioned are blatant lies or at least majorly distort the facts. It is your typical reference cherry picking, lets only mention one research result supporting your position while disregarding the other 20 results that disagree with your position.
My 9 month old Beagle was normal until she got spayed. Sure, she chewed and ate things she’s not supposed to, but that’s how puppies are supposed to be. Since she got spayed, however, she is in permanent Ms. Hyde mode. She rips up every last thing that isn’t mailed down, eats every last thing, has destroyed furniture, rugs and has become far more aggressive than she should EVER be. We’ve had her looked at and they said “oh, she’s fine, she’s just being a puppy.” Wrong. What this article fails to disclose is there is a percentage of female dogs, when spayed, that seem to go completely bonkers and become machines of utter destruction. My dog is not bored, she is not lacking in stimulation or play time. Her operation, which I’m now starting to regret, flipped a switch in her head that seemingly has no off switch. What the veterinarian failed to mention to us is that the dog was in heat when we had her operation – until AFTER the operation. Meanwhile, there were no visible signs of her having gone into heat before she had the operation. I lack the scientific or medical background to fully understand the ins and outs of this kind of thing, but something tells me you shouldn’t be performing a spaying on a dog while they are in their cycle. Someone out there, please explain to me what exactly is going on with my dog, otherwise I may have no choice than to put her to sleep. She’s had all of her shots eats right, gets plenty of exercise and always has something fun to do. I cannot turn my back on her, though, because as soon as I do, she begins to destroy my house, yard and attack my 7 year-old son.
Michelle Schenker (Admin)
Hi Chris, So sorry to hear your dog is acting up. We have added a few additional notes to our article based on your feedback and some research. While we did not find much on this subject, most report reduced aggressions, anxiety, etc. We did find this one study that I thought you might find interesting. Take care and if anyone in our community has any helpful advice, please share.
That research was done in 1997 and the article in 2009. That’s a decade ago.

Thats so sad to read. I sure hope things have gotten better?
I find this article lacking in newer scientific research. The part about behavior does not meet current research. Females especially in large breeds should have one heat especially if they have a tipped urethra. Larger breed males in particular have increased incidences in several cancers. You can do a ovarian sparing spay and keep hormones normal for females with no chance of pregnancy and you can do a vasectomy in males. To give people a quarter of the truth without the other options is just pushing an agenda. I have intact females who are contained in our home while cycling. In 20 years never had an oops. I have also had intact males which I kept separate and again no oops. Not luck but a firm understanding of reproductive systems and health. I choose to do ovarian spays on my girls and have been pleased with their energy, athleticism , decreased number of fatty cell lumps and increased quality and quantity of life. Dogs are mammals the laws of hormones don’t change. Women who have surgery induced menopause take hormones because they are essential, Dogs need to mature physically and psychologically. If one insists one removing all hormones at least wait until long bone growth is stopped by adult hormones and correct musculature is formed. Especially in large athletic dogs.
roger c
in humans to prevent a pregnancy they cut and tie tubes instead of an entire hysterectomy. why don’t they do this in dogs?

Roger, great question! For female dogs, the answer is more straightforward than with males. If a female dogs’ tubes are tied (tubal ligation) only vs. spaying (removal of the ovaries), then she will continue to produce hormones which will result in her normal “heat” or fertility cycles. During her cycle, she will also be more interested in mating which could lead to more aggressive and uncontrollable behaviors.

The more aggressive behaviors from the continued presence of hormones also apply to male dogs when only a vasectomy is performed. A vasectomy removes part of the sperm channel to prevent the sperm from ever reaching the outside world (or female egg) but leaves the other parts intact. Neutering removes all of the sexual organs in a male dog, eliminating the hormonally driven behaviors as well.

All of this being said, this is becoming a more controversial discussion in the veterinary world due to higher risks and costs associated with full sexual organ removals vs. less invasive surgeries such as vasectomy and tubal ligation. There is also some information supporting benefits of the sexual hormones that we are removing from most pets with spay/neuter procedures.

Blatantly untrue. First of all neutering does NOT remove ALL sexual organs obviously. And there is a LOT more information supporting the decision to leave males intact
Spay and neuter is definitely important! Far too many animals end up homeless, in shelters, euthanized, abused, etc. Spaying and neutering your pets could potentially help decrease the amount of suffering animals. I currently have 2 dogs. One was a rescued female doberman mix. She was dumped on the side of the road starving and someone had taken her off the streets and I ended up taking her into our family. She was spayed recently, along with being fully vaccinated and she received a clean bill of health from the vet as well thank goodness. For those owners who find that spay and neuter costs too much, I strongly recommend a low cost clinic. I had taken her to an SPCA clinic and they spayed her, ran tests on her, gave all of her vaccines (rabies included), and microchipped her, and sent us home with pain pills for her. she was actually pregnant as they did add a $10 fee for her being pregnant). If I remember correctly her spay was $65 plus the $10 pregnancy fee, vaccines were $50 all together, microchip was $15. The tests they ran we’re free.
They did a wonderful job with her. And she healed up extremely well. I will be taking my male blue heeler mix in next,and then our kitten we recently rescued!

After 10 years my westie bitch has started to rip up carpets and chew at doors. We’ve tried everything from tranquilisers to thunder jackets, but nothing works.

Would spaying help to calm her down?

I had my beautiful baby girl American bulldog spayed at the humane society on 8-19 and she started acting like herself again by day two. On 8-21 she was being leash walked down the back alley to potty when the neabor dog started barking and of course Pandora got excited and started pulling to get to the fence. When doing so she hemeridged and ultimately had a stroke and died almost immediately!! I have never been so heartbroken in my life as she was my best friend and we spent every moment of every day together since she was six weeks! Wherever I went she went and now since all I can think is that having her spayed was the worst decision I could have made! I don’t understand how a dog as heathy she was could die from this that easy? I followed the post recovery to a tee but after she passed i became obligated to do my own homework on the subject and this procedure is definitely far more delicate then they perseve it and in turn it caused my beloved Pandora to cut her life so prematurely! It cut me so deep that I’ll never forgive myself for having it done and I’ll never forgive the humane society for making this procedure seem so common and standard! It is Def far more dangerous and risky then they say it is! I have never had such a close bond with a dog and now I’m totally weiry about ever getting another dog bc the heartbreak is so severe and I doubt that I’ll ever get over this nightmare! I worked with her so much and had her trained so well just to have her life taken and my soul absolutely shattered! Point is if u ever have this surgery done please REALLY DO YOUR HOMEWORK BF HAND SO U CAN LEARN ALL THE PREVENTATIVES POSSIBLE! NOBODY SHOULD EVER HAVE TO SUFFER THIS KIND OF LOSS! I LOVE YOU PANDORA GIRL FOREVER!
It’s really a sad story! Brought tears to my eyes.,but I bet if you look at all the statistics Of all dogs that have been spayed, the results are not fatal. I would surmise that in a rare case something like this could happen.

Can a male dog perform the duty to feamsle..get hung upbut no way he can get her pregnsnt
I am not sure why people on here believed their dog changed after surgery.

I have had beagles growing up all my life. None of them spayed until I moved out on my own and got a female beagle. The first beagle died of cancer at 10yrs old and was not spayed. The other died of cancer at 12yrs old and had an enlarged heart for a couple years prior, was not spayed. The other is currently 8yrs old and has seizures a couple times a year and hasn’t been spayed. The other who hasn’t been spayed is 2yrs old and has seizures and had a bad reaction and almost died with a distemper inject. These are conditions from 4 beagles not spayed.

My beagle we spayed at around 4 months old. She is great, although at the time I felt guilty putting her through it, we are so glad we did. She is smart, energetic, lovable, and also playful. It’s almost like she continues to have her playful puppy habits (running in backyard, playing with her toys, always chewing on bones) but listens much better.

She will be three soon, not only is she really active and healthy but she and we don’t have to deal with spotting. This was my experience with spaying my dog and having a dog spayed for the first time, very glad we did and do not regret it. The only worries was any complications during or after the surgery. Everything went fine, she was tired the first day, but the next day she was up running around playing. Of course we made sure she didn’t jump or go up stairs for two weeks, and that went by fast. Here I am almost 3yrs later sharing my experience.

Wait until she’s 10 to see if she has cancer. No studies prove that it does.
I understand the benefits of spaying and neutering. But there are also downsides to taking away a dog’s ability to produce sex hormones. It’s important to understand both the pros and cons. Few vets give you information about the cons.
I spayed my dog and had negative changes in behavior, in her physical stance, in her playing habits. She can no longer chase a ball. She can’t find me to come to me when I call her. What could have caused this?
i know it has been a while ago but did your dog ever end up going back to its normal habits?
My dog changed drastically when I had her spayed. I regret it so much. She is the opposite of many things she was that I loved so much. If your dog is not having problems, especially if she is very feminine (or your male is a real “man”) as mine was, don’t risk losing that. Her intelligence is extremely diminished. She went from graceful to spastic, from very alert and involved to indifferent.
I have come across this article as my dog has just started her first season. I am quite concerned with what I am reading. I asked my vet and another local vet about spaying my dog and was told by both, that they wouldn’t spay her until she had gone through one season. Further to this, my vet actually advised me, on medical grounds, to allow my dog to have two seasons. Apparently the hormones released in her body during this time may help cure her little “accident” problem (she sometimes has a little wee while sleeping) without her needing to have medication. Are you telling me that this information from my vet is wrong? I have no desire to have my dog have puppies, (I once owned a cat who had been a breeding cat prior to my owning her and I saw the damage her last pregnancy did to her) I am only trying to look out for my dog’s well being.
There is a lot of research now that suggests it is much better for the dog’s health to wait to spay or neuter. The benefits are many – decreased risk of incontinence, decreased risk of certain bone cancers, hip and bone abnormalities… you can look up the studies yourself (UC Davis conducted a few). I for one am waiting until my dog is at least a year old before I spay her. The risk for certain female cancers increases, but the decrease in risk for other potentially physically debilitating issues is worth it to me.
I know it’s just under two years since your post but after reading that article from start to finish, I was mortified. The claims that the writer makes are horrifying! If you spay or neuter a puppy as young as she claims you should, it could end up with all sorts of bone defects not to mention other problems. I really hope you listened to your vet & let your dog have at least one season before having her spayed. Dogs need a whole year to put themselves together – for their growth in every way to be as healthy as possible. I’m having one of my girls spayed in a few weeks and she is almost five. The only reason she’s being spayed is because she’s started to get heavy seasons and becomes very hormonal, clingy & miserable.

I’ve had dogs all my life, my mother used to breed and I’ve also bred (from health certified and KC reg’d dogs), my pups have always gone to good homes that I have always kept in touch with – with a guarantee that if for any reason their owners can’t keep them then they will always have a home back with me – so not all pedigree dogs will end up in shelters. Maybe it’s 30% in the USA but here in the UK it’s rare to find a well bred pedigree dog in a shelter – & even then the breeder or breed clubs will usually work hard to pull them so that they go to knowledgeable homes. The writer is also incorrect where she states ‘Finding homes for all of the puppies bred is a great thing; however, as far as animals in the shelter are concerned, it is not such a great thing. The individuals that took in those puppies are individuals who could have saved a dog from a local shelter or rescue group. This means that there is now one less home and one less second chance for a dog in need.’ A lot of people won’t get rescue dogs because of their unknown history and they’d rather buy a puppy or an older dog that has been ‘run on’ (to see if it is up to show or breeding standard) from a good breeder – because that breeder will know the temperaments of the parents and can also usually tell the character of the pup by the time they are ready to go to their new homes – and most certainly not at 8 weeks – mine NEVER leave until at least 12 weeks!

Even with intact males in the home it’s possible to keep them separate from bitches in season, without accidents and without either sex getting stressed and if you have an intact dog (of either sex) then you should, as far as I am concerned, have a fenced in garden with a fence that is at least 6ft high to prevent your dogs getting out or others getting in.

Apologies for the rant but this writer obviously knows nothing at all about dogs and has downloaded snippets from the internet, deciding to try and make herself look like an expert. I’ve met plenty of them in my time & they always know better than someone who is a breeder of 40 or even 50 yrs standing (incidentally, the term ‘breeder’ doesn’t mean someone who is constantly breeding – most of us only breed to further improve on our breed and because we need to keep our show lines going (show dogs are still very pampered pets that are allowed to be normal dogs and get muddy etc). We rarely have litters – sometimes 1 or 2 a year and sometimes 1 in 3 years)! I’ve been breeding many years but still look to my mentors & peers for advice when I come up against something new or different as does every other breeder I know!
