Dog eating grass (caption: Why Dogs Eat Grass & How To Stop)Our dogs often do things that we struggle to understand. One of those things is eating grass. While we may feed our dogs a perfectly well-balanced diet and provide them with all the stimulation they need, they may still take to consuming grass.

Puppies eating grass is common too. There are many theories behind why our canine friends impersonate cows chewing cud, and we are going to take a shot at the reasoning behind them.

Article Overview

Should I Worry About My Dog Eating Grass?

Most owners research dogs eating grass to determine whether or not they should be worried about it. The consensus is that grass eating is not generally a problematic behavior. There are a few incidences where it should not be allowed, and we can often deter grass-eating with a few simple fixes.

Be Careful In These Cases

First, let’s focus on situations where you should prevent grass-eating at all costs. The most critical concern is when the grass has been treated with chemicals. In most public locations, a warning sign of possible pesticides or chemicals must be displayed to alert owners to keep pets off the grass. Not only can dogs ingest these chemicals by eating grass, but they may also lick them off their paws after walking on contaminated ground.

When there’s treated grass, ALWAYS steer your dogs away from the affected area. Reports show pesticides are among the leading causes of pet poisoning in veterinarians’ offices.

Secondly, when a dog consumes grass and vomits, immediately stop them from ingesting more. As with humans, repeated vomiting can damage internal organs and teeth. When a dog consumes grass and then throws up quickly, there may not be anything physically wrong, but it is important to determine any underlying concerns.

Keep A Watchful Eye

Dog in GrassEven when a dog eats grass and shows no indication of physical illness, it is still crucial to keep an eye out.

In addition to pesticides and herbicides, grass can also hold fecal residue containing parasites such as hookworms. These parasites can live in even a small amount of waste residue. When consumed, the parasite can take up residence in the dog’s intestinal tract, causing an active infection that must be treated.

Theories On Why They Do It

So, why do dogs eat grass exactly? Theories vary from psychological or physical concerns to natural instincts. And the reasons may differ vastly between two dogs.

Natural Instinct

Many believe that dogs eat grass because it is a natural instinct. Remember, dogs are omnivores. Before dogs were domesticated, they fed naturally on anything they could scavenge, and as a result, they received the majority of their dietary needs from single prey. Today we feed our dog’s scientifically balanced food, but dogs used to eat the entire game (meat, bones, organs, and stomach content). Dog rolling on ground in poop (caption: Why Do Dogs Roll In Poop?)This resulted in a well-balanced diet, including plants that found in the preys’ stomachs.

Dogs no longer hunt for their food, but some still possess the natural scavenging instinct. Like some dogs rub themselves in feces to disguise their scent, some instinctively eat grass as an alternative food source.

Still today, wild dogs eat fruiting plants, vegetation, and grass. But for domesticated dogs, grass is the most convenient item to satisfy this innate drive. While this makes it difficult to deter this behavior, it also doesn’t cause ill health effects. So, in most cases, it’s okay to allow your canine the odd graze from time to time.

A Psychological Condition

Some believe that grass eating is a sign of psychological imbalance in dogs. However, this is Sad dog in the dark (caption: Is Your Dog Depressed?)generally not the case. There may be some incidences where severe anxiety turns a dog to grass eating as a compulsive behavior. When anxious dogs become extremely upset, just like people, they may turn to tasks that comfort them and for some dogs, this includes eating grass or chewing anything in sight.

If a dog shows evidence of extreme anxiety around the time of their grass eating, this may be a viable explanation for their behavior. There are numerous methods of tackling anxiety in dogs depending upon the source of the anxiety. For some dogs anxiety that causes unusual behavior can be treated through desensitization therapy, increased levels of exercise, vet approved herbal remedies, increased levels of companionship, nontraditional therapies or prescription medication.

It is important to consult a licensed veterinarian to find the right anxiety solution for any dog experiencing anxiety to find a treatment that would work most effectively for an individual dog.

To Induce Vomiting

One of the more common theories behind dogs that eat grass is that they do it as a means to vomit. To date the majority of research into dogs that eat grass finds that in most cases dogs do not display signs of being ill before eating grass and the majority of dogs that do eat grass do not vomit after doing so.

Interestingly however, one study reveals that there is some variety in the method in which dogs eat grass. Researchers find that dogs that eat grass slowly rarely vomit afterwards. Dogs that eat grass more rapidly almost always vomit. This finding raises the question as to whether dogs that do eat grass rapidly are doing so to relieve stomach discomfort after eating something that does not agree with them.

Dogs that take part in grass eating as a means to vomit will not be regular grass eaters and when they do eat grass it will, according to this theory, be a rapid feeding that almost immediately results in vomiting.

To Improve Digestion

Open probiotic container with measuring spoon (caption: Best Probiotic for dogs)Other people believe that dogs eat grass as a means of improving their own digestion. Just how can grass improve a dog’s digestion? Grass provides “roughage” or fiber that may otherwise be missing from a dog’s diet and in these cases dogs eat grass to supplement fiber that is missing from their regular diet. Dog’s bodies, like humans, have specific nutritional needs and when a dog is not receiving those specified needs some functions are not going to perform normally.

In the case of a lack in fiber, a dog will not be able to digest and excrete waste products properly and this may lead the dog to feed on grass to increase their fiber intake and make their stools easier to pass. Learn more about probiotics to help improve your dog’s digestion.

To Gain Attention Or Out Of Boredom

One reason for dogs eating grass that often goes unspoken is the potential that a dog is simply taking part in a forbidden behavior as a means to gain attention or out of boredom. In cases where owners are simply not providing their dog with enough interaction and exercise, the dog may try to gain interaction with their owner through engaging in forbidden behaviors. As with younger children, attention is attention and it is possible that a dog that eats grass is trying to tell its owner that it needs more attention from them much as the naughty toddler who draws on the walls would do.

Dog jumping agility course pole (caption: How To Get Started In Dog Sports)In some cases a dog will entertain itself by being destructive and chewing through furniture, in other cases a dog will entertain itself by finding something – anything – to do and this can include eating grass. Of all of the explanations for grass eating that require solutions, these two are among the easiest to fix.

If you suspect that your dog is eating grass to get attention or stave away boredom, create a routine that involves your dog in more interaction, physical exercise and mental stimulation. These things can be achieved through allowing your dog to live within your home with you (dogs are pack animals and were never meant to live solitary lives,) walking your dog frequently or placing them in a daycare setting and enrolling your dog in training or sporting activities.

Maybe Your Dog Simply Enjoys Grass

Another theory for why dogs eat grass that often gets overlooked is the idea that dogs eat grass simply because they enjoy it.  As humans eat strawberries because they enjoy the taste, some dogs eat grass because they enjoy the way that it tastes. Just as humans eat hard candy because they like the way the texture feels in their mouth, dogs can eat grass because they like the way it feels in their mouths.

There is no way to determine whether a dog is eating grass simply because they like it other than ruling out all other possible theories. In the case of a dog that eats grass because they enjoy it, grass-eating will seldom if ever cause vomiting. However, that does not mean that it cannot. Vomiting is an unpleasant experience but for some dogs the sensation or flavor of eating grass can be too much to make vomiting a deterrent from grass-eating behavior.

There will be a notable difference in a dog that eats grass because they enjoy doing so and a dog that is eating grass to induce vomiting. Dogs that show signs of feeling under the weather before eating grass are more often than not, not eating grass because they enjoy doing so – think of this like eating a chocolate bar when your stomach is aching.

Pica As Evidence of Dietary Imbalance

In humans, the condition known as pica is the compulsion to consume items that are not edible. In humans, pica can drive people to eat rocks, dirt, Styrofoam material and basically anything else that should not be eaten. The most common explanation for pica in humans is a mineral deficiency and this leads many researchers to believe that the very same could be true for dogs that eat grass.

Dog eating out of bowl in grass (caption: How To Change Dog Food)Many people believe that a dog with a dietary imbalance will turn to grass eating in an attempt to supplement their body with any missing nutrients, vitamins and minerals. Most commonly when this reason is given as a reason for eating grass, it is believed that the dog is attempting to supplement fiber. When dog owners suspect that grass eating is caused as a result of a low-fiber diet they should switch their dog to a food that has higher fiber content.

Keep in mind that even when switching your dog’s food as a result of nutritional needs, food changes should always be done slowly. Dogs have particularly sensitive digestive tracts and making a rapid alteration in your dog’s diet will cause gastric upset and leave your dog feeling very uncomfortable. We have an article dedicated on how to switch dog’s food safely.

Another method that some dog owners recommend is adding raw or lightly cooked vegetables to a dog’s daily diet in order to increase fiber content.

If you are considering this as a method for preventing your dog from eating grass it is important to speak with your veterinarian to find vegetables that will not have adverse effects on your pet’s health. Certain human foods can prove fatal to dogs so it is important to fully understand which vegetables and fruits are safe for dogs to eat before supplementing your dogs kibble with any nontraditional food.

Video: Why Do Dogs Eat Grass?

This short video from Better Homes & Gardens summarizes why dogs tend to eat grass.

How To Determine The Reason Your Dog Eats Grass

One of the most difficult things for grass eating dog owners, is identifying why their dog eats grass. The first step in making this determination is usually a visit to the dog’s veterinarian for a blood draw, fecal testing and urine testing to check for any potential abnormalities that may be causing their grass eating. As the dog’s owner, it is important that you take note of your dog’s demeanor when they do eat grass so that you can inform your dog’s veterinarian of any unusual behavior that could help to identify the cause of your dog’s behavior.

A good example of this is noting if your dog shows signs of nervousness or physical sickness before eating grass. Most often when veterinarians find no signs of sickness that could be causing your dogs behavior.

Train Your Dog To Stop

Your vet might suggest making dietary changes, undertaking training methods or simply ignoring the behavior with a watchful eye to ensure that the grass being eaten is not tainted. But many of the situations outlined above give simple to follow ways that grass eating can be deterred by addressing underlying problems.

In some cases however, where grass eating is simply the result of a dog’s natural instinct to eat grass or because a dog likes the taste of grass, owners may try to train their dog to stop their behavior. While in these cases dogs generally do not experience negative effects from grass eating, this behavior can prove to be dangerous for pet owners living in areas frequently treated with pesticides.

Dogs that are food oriented can quite easily be trained to stop their behavior with treat rewards (here are some recommended treats for training). Taking the dog out to use the bathroom or for a walk with treats in hand is the best way to tackle training these types of dogs, any time the dog is tempted towards grass use a treat to distract them towards the walking path instead.

Dogs that are less inclined toward food and more inclined towards affection can be trained using the same method but instead of treats utilize positive verbalizations and petting to reward desired behavior. Another method that is more commonly utilized is teaching the “heel” command. A dog that has successfully mastered the heel command will walk by its master’s heel regardless of distractions when walking.

If your dog needs some help, we suggest reading our article on Doggy Dan’s online training course. And if they still aren’t feeling well, they could have an issue unrelated to eating grass so read more about tips to cure their upset stomach.

My dog grazes on grass almost every day. I strangely have not been worried about it until now. It started a few years ago and now it’s a daily thing. He isn’t pedantic about it, but he acts like a cow lol.
I’m going to ask my vet, just in case, but I don’t think there’s a problem. Being a Labrador, renowned for eating anything and everything, it makes sense that he’d love it so much.

I never consider the fact that dogs eat grass to provoke themselves to burp when they feel sick. My son noticed our neighbor’s dog has been eating grass lately and burping it after. We will let him know so he can take his dog to a vet for evaluation because he might be sick.

My 2.5 yo Golden’s been eating grass since I got him as a puppy. I’m now wondering if it may be part of a food allergy. This week’s he’s had a major allergy event. His whole snout is swollen with bumps and we ended up at the vet twice trying to figure out the cause…

I think he might be allergic to the food he’s been getting for the last 2 yrs. one thing I noticed is that ever since I got him he loves to rub his snout in the grass and roll around on the lawn after every meal. Perhaps his food has been his face itchy all this time. I thought he was just happy to get to go outside. It didn’t seem like anything to worry about until recently when I increased the ground turkey to kibble ratio in his diet – by two fold. Couple of days later an his whole snout is covered with allergy postules.

So, my thought is that if his snout and lips are itching enough to roll around on the ground and try to scratch them on a regular basis then I bet he’s got an itchy throat and tongue as well. Perhaps his grass fetish has always been him trying to scratch an itchy in this mouth and throat. Unfortunately I can’t find anything online to back up this theory.

I guess it’s time for prescription dog food…

Every dog I have had has ate grass on time or another. Sometimes threw up the grass other times it came out of stool. My question is my dog Delilah is on antibiotics the vet gave her for a rash she has, and the 3rd day on this med she is eating grass again. I have heard grass cuts the lining of their stomach. Is this true & should I be concerned?

My 10 week old pup is eating grass compulsively. He coughs and gags or vomits after eating it and is now constipated. I can’t take him walking because he hasn’t has his parvo shot yet so I’m at a loss at how to stop him from eating the grass without keeping him inside all the time.

Hi Aimee,
Until you have the parvo shot, you might consider walking him on a leash in your yard. This would allow you to pull him back when he tries to eat grass.

Personally, watching my dog eat grass and observing her bowel movements, I have ascertained that the grass acts as a lubricant and helps pass fecal matter.

Hope this helps others to understand their dogs need to eat grass. My dog does not eat but one particular grass and she will seek out that one grass always.

Regular lawn grass does not attract her at all. She sniffs the air until she finds the grass she wants.

My dogs eating grass is not a problem – usually. But a serious fetish occasionally. He’ll go a few months before he gets another “attack”. If there’s no grass to be had, he’ll find something – almost anything. And when he gets his fill of whatever , it’s over til the next attack. Maybe months later, or maybe in a couple days. So far, I can usually quell this obsession with green beans. Can’t figure out the why!

I have two dogs a Schipperke and a toy poodle. If we feed them to many treats or the wrong foods they go out around the neighborhood looking for a particular type of grass to eat. I am trying to find out which type of grass it is so I can grow it for them and they don't have to go hunting it. I think it is like Tums are to humans.

I looked this up because my dog's stomach has been growling and gurgling this evening, then I found her outside eating grass. She has done this same thing, most always accompanied by the growling/gurgling stomach, several times in the last five years. I have to think the dog's stomach is upset or gassy (with all that noise) and this is instinctual for her to eat grass to aid herself in clearing up whatever upset she has going on in her little belly.

I found that my dog is very sensitive to certain proteins causing her stomach to growl and gurgle very loud. Sometimes you can hear it across the room! It took me 3 years of food testing to finally find duck to agree with her pretty well. She does not have food allergies, or runny stools. Just a bit of a sensitivity. She eats grass like a goat anyway but, on those occasional bad days, she begs to go outside over and over just to eat grass even more.

My dog eats grass continuously if given the opportunity. She also begs for fruit (oranges, bananas) loves carrots , radishes, broccoli, asparagus, lettuce, tomatoes etc. you can see the pattern. Sometimes she will be sleeping and she will wake up and have an anxious way about her and she will lead me to the fridge and beg for carrots. What is her problem…tummy problems? Appears that way to me, my concern is she getting her proper nutrients. She isn't loving her dry kibble but does eat a portion of it everyday.

This was a very well thought out article imho.  I have heard that dogs eating grass is a pretty big concern for pet parents. The author actually examines several of the more common theories as to why dogs eat grass. It seems to me that science has not really been able to come up with a solid answer, so I guess we are left to our devices.

One of the most common theories is that eating grass is natural instinct for dogs. The theory goes that dogs (before being domesticated) were, and still are, natural omnivores. They would eat the bodies and bones of their prey, which often included the contents of their stomach. This meant that the dog actually ate some plants and greenery as part of their well-balanced diet. Dogs still possess this scavenging instinct, even they most no longer have to hunt for their food.

It is this natural instinct which can lead to some interesting behavior. This includes those dogs who rub themselves in feces to hide their scent and even dogs who feel compelled to eat grass. I guess this sounds plausible, but you would think more dogs would be eating grass.

The first main conclusion reached by the author is that generally speaking, when a dog eats grass it is not usually a problem. Of course, this is not to say that you want your dog to be eating grass which has been doused by harmful chemicals. The idea here, as I understand it, is to simply keep an eye on the type of grass which is being eaten. Many dogs do eat grass from time to time. Usually there is nothing to worry about.

In addition to keeping a watchful eye on the grass which is being consumed, the good dog owner will also watch the pet for any additional signs of trouble. Even if your pet is not displaying any direct physical symptoms, there still may be an issue down the road. One of the problems to be aware of is that there can be a lot of bacteria in the grass. There may be fecal matter from other dogs, cats and other animals. It is quite possible for your four legged friend to ingest a hookworm (or other type of worm) which can lead to a potentially serious and costly intestinal treatment.

I also started doing some further research on my own about this topic. It turns out that dogs eating grass is a VERY common problem. I am amazed. But then again, I guess that wild dogs or those who have not been adopted and are out roaming around would probably be tempted from time to time with eating grass, especially if they were not able to find enough food and were hungry. One of the problems, though, is that so much of the grass in our country has been treated with artificial chemicals that can be dangerous for dogs. It seems that ingestion of pesticides and herbicides is one of the most common forms of pet poisoning. Additionally, even if the dog does not eat grass, they may carry these chemicals on their feet and then lick their paws later.

Obviously, if your dog eats grass and then vomits, this could be a problem as well. However, the author is quick to point out that repeated vomiting is more of a problem than something which only happens occasionally. Repeated vomiting can damage the internal organs and the teeth of a dog, so be very careful in such a situation.

My dog eats grass when she’s had something that upsets her stomach as she has ulcerative colitis she has also eaten grass when she has something stuck in her throat fur when grooming. The grass she eats when her stomach’s bad digests as if she knows exactly what she’s doing. When something is in her throat the grass can stay in her throat for 2 days then she regurgitates it back up in a woven ball, this also happened when I had another boxer that swallowed stones. He would throw the stone back up covered in woven grass that was not digested after a couple of days. I’ve often wondered about the two ways dogs do use grass but I do not stop my dogs as I think this is like self medicating.

Sounds like you dog may be sensitive to wheat. Just as more and more people cannot digest or tolerate wheat because wheat dna has been altered and is not longer digestible.

Try your pet on no wheat diet for a month and see if she stops vomiting.

My dog eats only one particular grass she seeks out by smell. It seems to act as a lubricant for her bowel movements. So I let her eat all she wants. No vomiting ever.

She drinks a lot so like people, she must crave the chlorophyll to clean and lubricate her system. Just my opinion.

I heart dogs, and have owned two different dogs. Fortunately, neither of them ever ate grass (at least that either myself or my family was aware of). However, after reading this article I now wonder quite a lot about the whole issue of dogs eating grass. I was not aware that this was even an issue, due to my own personal experiences. Yet, the author indicates that this is a fairly widespread problem.

The first question a dog owner might have regarding the issue of eating grass is whether or not this would be harmful to your dog. Personally, this was the first thing that came to mind. The author actually handles this subject quite well. A dog owner should definitely be concerned if the grass being consumed by the dog has been treated with any type of chemicals. If your own yard has been treated by a landscaping company or lawn/yard service, you may want to ask if anything they use could be considered harmful to pets. Additionally, the author also points out that in public areas such as parks, if the grass has been treated with anything it must be displayed. This can include pesticides and herbicides.

The author of this article actually goes into some interesting theories which have been proposed about why some dogs eat grass. First off all, it is noted that grass eating is generally not a problem for most dogs and not all dogs eat grass. Since not all dogs eat grass, my guess is that this is why there is so much interest in the subject. After all, if only some dogs barked, then this would probably be an area of study as well.

The theory which I think makes the most sense is that dogs will eat grass in order to relieve stomach discomfort or to help with digestion. The grass may actually provide some type of roughage that helps to aid the digestion of their food. It is akin to a person needing to eat more salad or vegetables to help their digestion.

It may also be possible that some dogs are eating grass in order to vomit. There is actually a scientific study which backs this theory. If a dog is having a lot of stomach discomfort they may go out and eat grass very fast. Then, after vomiting they feel much less discomfort.
