Dog Eating Grass Frantically – What Are The Reasons?

What Are The Reasons?

Is your dog eating grass? Do you wonder if it’s a good thing or a bad thing for him? There are several reasons why dogs eat grass, and some of these may be signs that something is wrong.

If he eats the grass just to munch on it, that can be one thing. However, if he seems to be having digestive issues and can’t keep anything down (including his favorite treats and dental chews for pets), then there could be something else going on. 

Read on to find out more about why is your dog eating grass frantically, how you can help alleviate the problem, and the red flags to look for.

Why Is Your Dog Eating Grass Frantically All Of A Sudden?

Upset Stomach

Dogs often use grass to soothe upset stomachs from overeating or eating too much. Because it is hard to digest, grass can soothe upset stomachs and cure any bubbling that may be occurring.

They may also feel more energetic and can throw up. This helps to get rid of bad food, which is often the solution. Sure, it’s not the nicest solution, but it works!


Dogs eating grass can be a sign of parasites. If you see your dog eating grass and then acting lethargic and low, it may be because he has worms and other parasites in his stomach.

If this is the case, try to get him to eat some yogurt with live cultures in it. These help fight any bad bacteria or parasites and can help your dog feel better if he is suffering.

Imbalanced Diet

Dogs eating grass can mean there is something wrong with their diet. If you have been feeding your dog the same type of food and he all of a sudden starts to eat grass, it may be because his body needs more minerals and nutrients than what’s in the food.

This doesn’t mean that your dog isn’t properly fed. It just means that its body needs a change, so you should try to switch up the food a little bit.

Before changing your dog’s diet, be sure to talk to your vet first and see what they recommend. You may find something better for your dog that doesn’t include as much grass-eating!

Fiber Deficiency

Dogs eating grass can also be a sign that they are lacking fiber in their diet. Dogs need a lot of fiber, and if they’re not getting it from their food or through other outside sources, then they may turn to grass.

If you feed your dog high-quality dry food that has a good amount of fiber in it, he should be fine. However, you can also give him carrots or peas to make sure that his digestive tract is working as it should.


Dogs eating grass and licking their bed can be a sign that your dog is bored. If you have a yard for your dog to run freely, but he spends the day inside alone, boredom can set in quickly. To fix this, play with him more in the yard or take him on walks so he can get out some of his energy.

If your dog seems to be bored a lot, you can also try giving him an interactive toy that he can use alone or with you.

These toys usually have a treat inside and a release where the dog has to move it around to get the treat out.

This will keep your dog entertained for long periods and provide him with the exercise he needs.

Actually Like The Grass

Finally, some dogs legitimately like to eat grass. It may not be because they’re lacking something or your dog is lacking nutrition. It may just be that they like the taste and smell of it.

If this is the case, then there really isn’t anything wrong with letting your dog enjoy a grass snack here and there. Just try to make sure he doesn’t eat too much of it to avoid any tummy aches.

It’s a good idea to keep an eye on your dog when he’s munching on the grass to see if something is going on. Otherwise, just let him snack away!

Red Flags You Should Look For When Your Dog Is Eating Grass

Dog Eating Grass Frantically And Panting Excessively

When your dog eats grass, he should be able to eat it at his own pace and mind his business. If he is eating the grass much more quickly than normal and then panting excessively, there may be something wrong.

This can mean that something in his stomach needs to come out or that he has an upset stomach because of something else.

In the case of something in his stomach, he may vomit or even get diarrhea. If your dog is eating grass and you see any signs of throwing up or having a bowel movement, call your vet right away to find out what’s wrong with your pet.

Dog Eating Grass And Coughing

If your dog is starting to cough when he eats grass, it may mean that there is something stuck in his throat or down his esophagus.

If you suspect this is the case, try to take him on a walk or let him outside so he can relieve himself. He will probably start to cough, which could be alarming if you don’t know what’s happening.

Once he has had time outside or some exercise, bring him back inside and keep an eye on him. If he continues to cough, take him to the vet as soon as possible.

Dog Eating Grass And Vomiting

If your dog is throwing up while eating grass, it could just mean that there was some food stuck in his system, and he’s getting rid of it.

It can also be a sign of several other things, such as worms or even more serious issues like cancer. Another reason could be poison such as pesticides as grass can absorb these.

If you aren’t sure what’s wrong with your dog and he is eating grass and vomiting, schedule a visit to the vet.

When You Need To Contact The Vet


If your dog is eating grass and suddenly has diarrhea or starts to vomit, you will need to contact the vet. Some of the causes for these symptoms include infection, parasites, poisonings, or major illnesses like cancer.

These symptoms can lead to major irritations or indigestions, so it’s important that you get your pet appropriate veterinary care as quickly as possible.

If you suspect that your dog is having trouble with his stomach because of something he ate, call the vet first before taking him for a walk. This way, you won’t aggravate an already sensitive situation which can be dangerous for both of you.


If your dog isn’t acting like his usual self, is lethargic, and doesn’t want to move much or go on walks, this can also be a sign of illness.

If your dog is eating grass while lethargic, this can mean something more serious than an upset stomach. He may have intestinal parasites or even a more major illness like cancer.

Lethargy is also one of the early signs of poison ingestion, so if you notice him eating grass and acting differently, it’s really important to get in contact with a vet as soon as possible.


If your dog is eating grass and then starts to shiver or act like he’s cold, this may be a sign of poisoning. There are several types of poisons that could cause these symptoms, so if you notice him doing this, get in touch with the vet right away.

Don’t give your dog any medication without talking to the vet first, though.

If your dog is eating grass and exhibiting other symptoms like shivering, vomiting, diarrhea, lethargy, or any other issue that concerns you, contact the vet immediately.

How to Stop Your Dog From Eating Grass Frantically?

Find The Source Of The Problem

You will need to find out why your dog is eating grass frantically. There are several reasons for this, but some of the most common ones include intestinal parasites, an upset stomach, and poisoning.

Make sure he’s getting enough food and water.

Sometimes dogs start to eat more grass because they’re not eating or drinking. If you think this might be the case, check your pet’s food and water. If he seems to have enough of either one, you might want to take him for a walk or play with him more to tire him out.

Some dogs act like they’re hungry even when they’ve just eaten, so it could be that your dog is not actually hungry but wants more.

Bring Him To The Vet

If you can’t find the source of your dog’s behavior, contact a vet right away.

In many cases, when a dog is eating grass frantically, it’s due to an upset stomach. If you notice your pet doing this, but he has recently had a meal and isn’t vomiting, then there may be something stuck in his system that he can’t eat or pass.

If your vet rules out an intestinal blockage, infection, poisoning, or major illness, then your dog may have a minor irritant in his stomach. 

Usually, they’ll prescribe a medication to help settle the inflammation and pain which will also reduce his appetite for grass.

Balance Their Diet

Your dog’s diet may be balanced, but sometimes dogs can develop sensitivities to certain foods. If this is the case, your vet will suggest changes in his diet to help keep him healthy.

He may need to eat less of one type of food and more of another. So you should introduce healthy fats in your dog’s diet.

A balanced diet of all-natural food can also help to promote a healthy digestive system for your pet – and alleviate your pup’s need to eat grass!

Keep Your Lawn Mowed

Keeping the lawns around your home nothing but a green carpet can help minimize your pet’s need for snacking on grass.

This will also minimize his risk of eating something other than grass, which can lead to illness or poisoning.

If you think logically, the less grass there is to eat, the less likely your dog will be tempted to eat grass!

The following things can help alleviate your pet’s cravings for grass:

1. Small, frequent meals throughout the day.
2. Limit or restrict his access to grass in your yard or nearby areas where he can go and snack on it whenever he pleases.
3. Give him natural supplements like green tea extract, which can help reduce nausea.

Do Dogs Eat Grass When They Are In Pain?

There are multiple reasons why your dog may eat grass. If you notice him eating a lot of it and showing signs of pain, then these could be related.

Vomiting and diarrhea can also lead to the need for grass-eating, as can nausea and indigestion. A lack of appetite is another sign that something could be wrong with your dog.

Your dog might also be eating grass to stop or prevent vomiting, which is a common symptom of conditions like pancreatitis, intestinal obstruction, and food poisoning.


If your dog is eating grass, look at the reasons why he’s doing this. Did you see him eat anything else? Is it something that tastes good to him? Monitor his behavior for any changes, and contact the vet if you notice anything unusual.

It could be boredom, an imbalanced diet, or an upset stomach that makes him eat it. Either way, find out the reason why and look for ways to prevent it from becoming a regular habit.  

If you have any questions or concerns, you should always visit or call your veterinarian – they are your best resource to ensure the health and well-being of your pets.
