Aggressive Dog

Most of the time, when you see an aggressive dog it wasn’t born that way. Owners of dogs just may not fully understand how to train their dog. This lack of training often leads to aggressive behavior in dogs because they are responding to situations using their instincts, and not proper training since they have never been taught differently.

Dogs become aggressive for a number of reasons. Normally, their aggression is born of fear or possessiveness. An owner who fails to see the signs of aggression as they develop will soon find themselves with a dog that is completely out of control. This is the owner’s responsibility, and does not mean that the dog is a “bad dog.” It just means it is time for some aggressive dog training tips to help you make your dog sweeter.

The Steps of Aggressive Behavior

If you pay attention, you will know that your dog is aggressive long before their behavior becomes serious. Here are some tips for looking for aggressive behaviors in your dog and how to end them.

Body Language

Dogs tend to use body language to intimidate; therefore your dog may try to situate himself so that he is taller than other animals. His hackles may rise, the dog may lock his gaze and display more control over the mouth muscles. Other forms are a tightly closed mouth, or lips stretched over the teeth. Your dog will be tense and will show signs of physical dominance.

Alpha Dog

Dogs are pack animals. In a pack, there is always a leader or “alpha dog.” If no leader is established then the dog will establish itself as the alpha and will be guided by instincts and how much control he has over people, other dogs, and situations. Even though dogs are pack animals, some dogs are naturally born shy and their aggression is the result of their fear. These dogs can be particularly vicious because they are often small dogs that the owner leaves unchecked, assuming the dog to be harmless because of its size.

In your home, you need to be the one to establish yourself as the alpha dog. You establish physical boundaries as well as behavioral boundaries. To do this, you must first teach the dog that you are the one in control.

Aggression is Not a Form of Punishment

Many dog owners punish aggressive dogs with aggressive behavior themselves. Rather than the dog learning to behave from this form of punishment, they learn that aggression is an accepted response. Remember that some aggression is born of fear. When you beat your dog, you might establish some fear and that may cause the dog to stop doing whatever it was punished for, but you also build a foundation for aggression to be acceptable. Sooner or later that fear you created may come out in aggressive behavior that is beyond your control. Instead, use specific methods to teach your dog what is acceptable and what is not.

Rather than using punishment to establish control, you can limit the dog’s abilities and following the pack order. Keep in mind that the alpha dog gets the best of everything, and first choice to decide what the best of everything is. The alpha dog is followed, not led. When you rely on punishment only, you are responding (following), rather than leading.

Leash Training

In order to establish yourself as the alpha dog in your home, you may have to use a leash inside your home. This is so that you can control where the dog is able to go. For instance, if you do not want your dog on the furniture, simply step on the leash when he goes to get on the couch. Prong collars and harnesses work well for this type of training because they do not choke the dog when he is being guided, but they do limit what he can do.


If your dog is the alpha dog, he sleeps in the best possible place. In most homes, this means he would sleep on the bed. This is fine once the dog understands he is not the alpha dog and that the alpha dog is allowing him to sleep in the bed, but you have to establish the pack relationship first. Your dog has to start at the back of the pack and work his way up. This might mean your dog has to sleep in a crate until he understands the chain of command.


The alpha dog has first choice when it comes to meal times. Since you are starting your dog at the back of the pack, he will be the last one fed. You may even find that you should crate him during meal times. He can progress to eating at the same time as you once boundaries have been established.


Playtime is one of the best times to focus on training your dog. Toys should be kept up so that when your dog gets a toy, you are the one to give it to him. When playtime is over, the toy is put up. If your dog takes off with a toy and you chase him, you are letting him know that he is the one in charge, not you. Instead of chasing the dog, wait for him to bring the toy back, then put it away and never give it to him again. (Please note, this does not mean not to give him a toy at all. It just means to get rid of that particular toy.)

Collars and Muzzles

Collars and muzzles can be very helpful when it comes to training your dog. They may seem like harsh forms of punishment at first, but they work better than regular collars because of the way they are made.

Prong Collars

Prong collars are among the best tools a trainer can use. A normal collar will choke your dog if you pull on it. A prong collar will cause superficial discomfort similar to what a pup feels when his mother nips him in the back of the neck, indicating that his behavior is not acceptable. We recommend the Starmark Training Collar as it is a little softer than the traditional metal prong collar and it has great reviews from professional dog trainers.


A muzzle is a great tool to use if you have a dog that snaps or tries to verbally intimidate other animals. This is usually what happens with shy dogs who are nervous in a situation. You must ease your dog into new social situations a little bit at a time. The muzzle can be used in social situations, but to train the dog correctly, put the muzzle on the dog for about an hour before a pleasurable activity such as eating or play time. Then the dog will come to associate the muzzle with pleasant activities and will apply this feeling to social situations.

Aggressive Dog General Training Concepts

When you are training your dog, be sure to reward him or her for good behavior. You can do this with a toy, a treat, or lavish praise. This lets the dog know he has pleased the alpha dog and may be moved from the back of the pack soon.

Have patience and introduce your dog to new ideas and settings a little at a time. If your dog is nervous around people, only expose him or her to people for a short period to begin with, petting him and reassuring him all the while. Your dog feels safer with an alpha dog indicating that all is well.

Growing up, Kimberly used to get the sniffles when she was around dogs. Thankfully, she grew out of her allergy and is now able to play and snuggle with dogs as much as she wants! She and her husband adopted Sally, a four-year-old hound mix, in early 2017, and she has brought so much joy into their lives. Life as pet parents has been very rewarding.

If you need to puppy house training for all habits, you should let him to join the best way to dog training classes in the market of Singapore.
I just recently bought a 2 month old puppy, we have 3 other dogs plus the new one the two oldest are fine with the puppy being around but my second youngest myloh who is a year and a half old is acting really aggressive around him, he tried to attack the puppy and barks constantly. I have tried taking them both on walks where myloh is in front and blue(the puppy) is behind that didn’t work and i currently have then separated from each other by a gate I front of the bedroom for since the puppy is mainly in there. But myloh barks at the meet sight of the other dog. I tried group training him but that didn’t work. I comfort him every time he sees the dog so he knows it’s okay but he just barks non stop I’m afraid he’ll never be accepting of him. I’m at a point where I don’t know what else to do please help!!
I recommend having a session together with your older dog and your puppy(Who i think is myloh but im not sure if thats the right dog) the older dog having a muzzle on and you playing with both of them or taking them on walks *Make sure to always keep the muzzle on when doing this until he stops barking* i would have another person walk one dog, if he keeps barking i would contact a professional dog behaviorist, this does not include petsmart or petco or anything like that, go to a place where dog training is all they focus on. Probably dont just bring them in i would call first because they may want to have them come in when no other dogs will be there.
My Male yorkie who is not even 2 yet has become aggressive towards my husband and is now growling at me
Other than that he can be a very good dog
Same situation to me. Just now. My dogs are brothers. I have this dog named chingoo who is chubbier than his brother named Brancho. Both are a year and 5 months old. Chigoo is always irritated, everytime he sees his brother, or if he did something like biting or eating something he is not allowed to eat and i am trying to take that thing away from him, he openly gets mad at me. Just this evening, he bite a neighbor. He is so aggressive. I don’t know what to do. Please help us. I don’t want to give up on him….
My name is Denise I have a question regarding aggressive play between my 2 dogs the puppy (6 mints ) plays extremely rough with biting. The other dog (2 years) is becoming less tolerant what can I do to decrease the biting during their play before something happens
Hello. I have a couple of issues with my dogs that started a few years ago. I have three siblings that I have had since they were puppies. I live in an area that is over populated with porcupine. My female seems to be the leader, sounding the alarm when she smells one one our property and all three of them with rip it to shreds. I have spent thousands in vet bills (probably close to 20,000) because they will not stop. I have tried shock collars, bark collars, muzzles, and wireless electric fence. They will not stop. My female also is aggressive towards other dogs. She has cause two injuries so far, but has attacked other dogs up to 10 times. She can strike at any moment, it could be right away or after she has played nicely with a dog for hours without issue. I have leash and muzzle for her for in public places and when around new dogs but she still gets very tense and growls when leashed and muzzled. Things I have tried walking her with a muzzle on leash with other new dogs and corrected her with “no” and making her submit when she does this. She continues to do this. The last incident occurred with a dog sitter when I was not in town. He has her unleashed and unmuzzled in a public area and she saw another dog and sprinted to it and attacked, causing injury to the dogs skin (skin flip). I don’t know what to do. I am thinking about rehomeing her but how can I when she has this issues. I would really love some guidance on this. She is an alpha. When I have her out she is always on leash, when other dogs are around the muzzle is on. I really do not want to have to put her down, but it is getting out of control. My life revolves around these dogs but she really can not be trusted. Any advise would be helpful. I am constantly stressed out, when I go anywhere I don’t enjoy it because I am constantly worried about if something has happened with my dogs because they are either attacking porcupine or she is attacking other dogs.
I have the same issues and feel the same way you do. I have had personal one on one training as well as group training for my dog. He is very over protective of his territory and/or me. I will not put him down. He is muzzled in public and leashed. I have put him on CBD oil (for dogs). Right now he is the only dog in the family. At this point I would be fearful of bringing in another dog but it might help. He has settled down a little since I have put him on CBD oil but I don’t feel this is the only answer. I am looking for advise as well.
Thanks for the article, my girlfriend and I have recently adopted 3-4yr Stratford terroir/Schnauzer. He is the most loving dog toward people I have ever been around. He does suffer from boundary issues, if my gf and I are sitting on the county he wants to be right in the middle or on top of us, he doesn’t sleep with us though. But if we are on the couch he will army crawl to us to make sure we are paying attention to him. However, saying he doesn’t get along with other dogs is the understatement of the year. Recently he got out while my gf was answering the front door and our neighbors where walking his dogs at the same time and what insued was a chaos until I was able to run down the stairs and grab him up. Luckily no dogs where hurt. But we don’t want to wait for another dog to be injured. We have talked to local trainers but they insist us bringing Teddy to a group training class which I’m worried will be just bring more chaos. Any suggestions…. please help.

You are right to be nervous about starting with a group class. We would recommend that you find someone who will do individual training sessions with you until you have the behavior a bit more under control. Then, you could consider a group training class.

Hi, we have joined the Rover dog sitting family and have our first aggressive dog. He was not aggressive when we did the “meet and greet”. I feel sorry for the dog because he was not trained as a puppy. He is now 4 1/2 years old. For the safety of the other dogs I have to keep him separated and that doesn’t seem fair to him..Any suggestions?
Hello. My dog is 6 years old and he is very mean to strangers. He really hasn’t ever been exposed to other people much so I think that is part of the problem. I recently brought him to my college apartment with me and with 2 of my roommates he is completely fine but with the others he has bite one. I’m really just looking for recommendations on how to change this behavior so that my roommates aren’t afraid of him.
Hi, I have an adopted street dog from Mexico. He is 2 years old and weighs about 13 lbs. The rescue dog is a very sweet, affectionate and calm dog until the Yorkie comes over. Before I got this dog my daughter lived with me with her dog. Her dog is a 7 year old Yorkie. The Yorkie grew up in our home and recently moved out with my daughter about a year ago. Over the last year I get her dog on some weekends to sit. Problem is both dogs are very territorial. They are both trying to be the alpha. It’s my house, I am trying to lay down the rules that I am the alpha not them. The rescue dog can get quite mean, snapping and growling and even physically attacking the Yorkie. My daughter is going on vacation for 2 weeks the middle of September and I am dreading having these 2 dogs together. I have been reading Cesar’s books and Sophia Lin’s book but not having much luck. Any suggestions that would help me would be greatly appreciated.
Hi I need help! I have a 25 month old dachshund who HATES bed time. As soon as he know we’re are going to say I s hedtome it try to pick him up to carry him to bed he turns awfully aggressive.

We have two Shih Tzus. One is almost 10 and very gentle and laid back. The other we rescued from a box in a parking lot about 4-5 years ago. At the time the rescue, according to our vet was about 2-3 years old so now is about 7 probably. The rescue is also a lot smaller than our other one. They are both male. They got along famously until about 6-8 months ago and our little rescue started acting out aggressively – started the stare down thing the would basically attack our older one. No provocation what so every. It seems to be getting worse and now happens several times a week if not more. It seems the little one really would not hurt the older one, however, now we have an older dog that is skittish and pretty much afraid of the little one. I know Alpha dog. But my question is how do we remedy this. My husband said, after a pretty serious attack last evening, now the two have been playing like best buddies today. Don’t know what to do and do not want to get rid of the little guy. But we can’t have our older dog cowering all the time either. Help!!!!
try putting both of them on a leash bring the big dog outside first then a few minutes later bring the little one out if the little one lays down or rolls or anything like that than the little dog knows that the older dog in the alpha but make sure to have the older dog standing until the little dog gets down .
We have a terrier mix with a lot of behavior issues. It stems from my grandma and dad who have terrible dog training ideas. I try to train him, but I can do very little and then they undo everything I have done.

I have tried to have honest conversations with them, but they respond with statements like “you don’t know what you are doing/talking about”, “this is how we always raised dogs”, “you’re just being mean to the dog”.

When he bites, they say that it’s his only form of communication. Then they pick him up and praise him for letting them know he was bothered about something. When he barks, they sit there and scream at him. He will sit next to them and whine until they pick him up like a baby and rub him. Ifbhe doesn’t eat his food, they give him their food.

I’m at a loss as before I can train the dog, I have to train people who have no interest in learning or changing.

Any ideas?

I just got a Rottweiler/Labrador/Mastiff. He is almost 4 months old but when I try to punish him or do anything he gets more aggressive. When he bites i put his paw in his mouth that didn’t work so I also tried to push his tongue just a tiny bit, roll his lips so he bites them instead and I’ve even tapped him on his nose. He just gets angry and it gets worse. He will bite harder and in places where I can’t see him coming. He gets aggressive when I touch him or try to pet him or kiss him.
You are not teaching him anything but aggressive behaviour by doing those weird actions? He needs professional training otherwise you will have a very dangerous dog that even you cannot handle.

I have a (almost) 3 year old shihtzu who is very agressive with us and strangers. He was friendly as a puppy and when he turned around one-ish he started to bark excessively around strangers. After a couple hours with the strangers he would adjust and be fine. Things have gotten way worse and although he doesn’t bite strangers we’re afraid he might at some point get the courage. He barks extremely aggressively and lunges at strangers and dogs and even our iguana who has free roamed the house alongside the dog since we got him. When we try to take food or a chew bone away from him he bites in rapid hard bites and shakes. When we try to correct his behaviors he bites as well. We’ve tried various methods and products including the doggy dazer, shake and break, and even a spray bottle, but nothing is even making him flinch. We’ve done different training methods and try to establish ourselves as top dogs but just when we think he has the concept he starts to protest and argue again and starts back where he was before. We’re considering using a shock collar. Please help!
I have a 3 year old Chihuahua. He is aggressive to people and dogs outside of the apt. He gets nervous when people come over and barks at them. But after a little bit he will be fine with them. But when i take him outside and he sees people and other dogs he barks aggressively and tries to go after them. He did that this morning and i blocked him then he bite me in the foot. Just wondering how i can help him. Pls help
Help. Our dog is 9 and just became aggressive this past year. He charges us and visitors and snarls and nips. He had spinal surgery 2 years ago so we are afraid of hurting him but now afraid of him. Oddly when at vet or grooming he doesn’t have to be muzzled though we recommend it. We would be afraid to TRY to muzzle him ourselves! At end of our ropes. Any help appreciated!

PS He was neutered many years ago but still shows mounting behavior to our female. He is also aggressive with and started fights with her. She is a sweetheart who tries to protect us. HELP My husband is considering drastic I can’t speak it action.

Need help please. Adopted a 2 year 6 months old male dog from Stray Rescue St Louis. He is very aggressive towards people and others dogs, he lived in this shelter for all these years. I do not know what his background is. I am very worried. I do not want to take this dog back. He is very good in our house. No pee or poop or tearing things up. He has learned commands. We have had him almost 60 days now. I live in a Condo and there are always people and dogs out. I keep treats in my pocket to distract him. Please help.

Hi I need some serious help my dog has been attacked 3 times and I got him done and all of a sudden he has turned on other dogs and cats and some humans and I don’t know why or what I can do to stop this
He’s afraid. He wants to scare them before they get him. You will need to work with socialization to rebuild his confidence.
Paige Pflieger
My dog, beau, is a chow chow/lab mix and is very agressive towards other people and dogs. He has now bit multiple people and almost jumps over the bar in our kitchen when people come over. He goes absolutely insane. I love him with all my heart, but if this continues, we’re going to have to send him to a shelter. I’m not sure if it’s genetics or learned aggression, but it’s possible it’s both. He’s an non-neutered male dog, but neutering is so expensive I don’t know if we can afford it. Any suggestions on places or shelters that are known to do the procedure for a reasonable price?
Hey there! I’m not sure if everywhere has these, but where I live there’s a pet clinic called the Angels of Assisi and they do nuetering with microchipping for only $60. I say do some research and see if there is a place similar near you 🙂
We have two male dogs: a 3 yo lab and a 10 month old lab/husky mix. They got along so well. Older lab gently guiding and correcting lab/husky when he became aggressive or possessive. When my son brought his female (11 mos) lab/pit mix home from college everything changed. Female runs up to our lab, biting at his mouth when he barks. Our lab/husky has grown to 90-100 lbs. He does the same thing to our lab. I noticed this when I accompanied my husband on the dog’s morning walk (one hour) unleashed in open land area. I was appalled. My husband seemed un-alarmed and stated that’s just what they do. My younger son and I took the dogs today and leashed both younger dogs for part of the walk. There was no biting and we encouraged their correct behavior. The younger two pups will be signed up for behavior training tomorrow, but my 3 yo lab is not eating as much nor playing. I’ve been trying to figure it out. I thought the additional pup was to blame but the aggression must be too. Am I too late in correcting and training the other two dogs? I feel horrible. He was always so happy. He’s brought so much joy to our family.
I have a 10 year old male miniature poodle that is very sweet to people, including strangers but is extremely aggressive to our puppy. He does not immediately growl and snap when he sees her, but only when she comes near his body and tries to sniff him. She doesn’t bite or try to harass him at all, but he still gets extremely aggressive and tries to bite her. Also when I was holding him, I began to pet the puppy and he immediately started growling. I think he’s possessive over me. I have no idea how to correct this behavior and I desperately need help! If anyone knows how I can fix this, please reply.

Can moving cause a year old dog to become aggressive towards people and animals she’s not used to being around? If so how can I get her to feel happy and safe in the new environment?
Tabitha Moore
I have a 4.5 year old Mini Schnauzer female, she is a real sweetheart with people. She lives with 2 other females & they all get along. My problem is when we walk in public & she sees anyone especially dogs she becomes uncontrollable. She squeaks & pulls no matter what I do she will not stop. She gets the other 2 going, I know she is the problem. If I allow her to come in contact with the dog she will nip at them. What can I do to stop her? She will see anything dog or human coming within hundreds of feet, so this behavior starts rather early & lasts until they pass. Please help
Paula Gomes
I have a 3yr old chihuahua that I rescued 2wks ago she loves us and my other dog too. When I take her out she’s an aggressive barker and shows her teeth to other dogs wanting to jump on them. How can I change this also I had a visitor who had a sweet small dog and my chihuahua wanted to just rip her apart as a result I put her away. What should I’ve done differently? I can’t afford trainers but I do want to keep my dog.

It sounds more like you need a animal behavior specialist. My dog is 5 and she behaves similar to how your dog is but she has never growled at me or any members of my family. She barks at everyone and doesn’t calm down. I contacted an animal behavior specialist and he said the first step is admitting that you have an aggressive dog and then a behavior specialist can help you. And you need to exercise her like crazy. Do you play with her or did you play with her a lot as a puppy?

I love all my dogs the same.

please help.


What kind of training have YOU personally done with this dog? Sounds like you’re not the leader, or below the leader. Try muzzling, and working with the dog in a new environment. This could mean walking around the neighborhood, or going to a new park. Put your dog on a corrective collar (Prong, gentle leader, training choke chain), and just work with him. Giving him rewards when he does the desired task you’ve given him, and giving him corrections when he has not. If this doesn’t work, I’d consult a trainer before making any drastic decisions. Everything is fixable, you just have to make the time and financial sacrifice to do so.

I have the exact same problem! I adopted a shelter dog. She HATES MY GUTS! Barks uncontrollably, and would have literally eaten me up if my dad hadn’t been here to hold off from me. I love my dogs, too. HELP!
Mary Anderson
Colleen, was he your first dog? Did you get younger dogs? Was he more your dog? Sounds like jealousy? Read my last post, I am having similar issues
