Many dog owners have noticed their dog eating grass and vomiting at some point. You might be wondering why my dog is eating grass and then puking. Is it normal to eat grass? or Is grass safe for my dog to eat?

In this article, I will answer all your questions,

The most common reason for dogs eating grass is nutritional deficiency. When dogs eat unusual and non-food items (such as grass), which is technically known as Pica, it indicates that your dog is not getting enough vitamins, minerals, fibre, or chlorophyll (both of which aid in digestion).

Aside from that, there are a few more reasons why your dog is eating grass and how you can stop it.

Common Reasons Why Dogs Eat Grass

1. Your dog enjoys it

The most straightforward explanation for why dogs eat grass is that they enjoy the taste of it. Dogs may enjoy the texture and flavour of grass in their mouths.

Canines, as natural scavengers, are programmed to seek nutrition wherever it can be found. It’s possible that your dog enjoys the taste or texture of grass. Or it could be meeting a nutritional need that his regular food isn’t, particularly fibre.

2. Your dog is Bored or Anxious

Eating grass is just a fun way to pass the time. Boredom can be alleviated by providing adequate mental and physical exercise and stimulation. Every dog owner should have a routine for exercising their dog.

Taking your dog for a walk or playing intense games like tug of war or fetch can tyre your dog out and reduce the likelihood of boredom.

If you force your dog to sit perfectly, he will become bored and anxious. You can keep your dog entertained by providing him with chewing toys or bones.

3. Your dog is Nutritionally Deficient

One of the most common causes of your dog nibbling on grass is a lack of a well-balanced diet. If your dog’s diet does not provide enough fibre, he or she may eat grass to meet his or her body’s fibre needs.

Consult your veterinarian for a diet plan tailored to your pet’s specific needs.

4. Your dog is having a Upset Stomach

Many times, dogs will eat grass to self-heal an upset stomach. Grass acts as a medicine, allowing your dog to get some relief from their upset stomach.

However, most studies have found that this is extremely rare — less than 25% of dogs vomit after eating grass, and only 10% show signs of illness beforehand.

The grass blades tickle the throat and the lining of the stomach. This helps the dog vomit, and your pet is relieved of the discomfort caused by indigestion or an upset stomach.

5. You dog is fulfilling Roughage needs

Dogs require roughage in their diets, and grass is an excellent source of fibre. Because a dog’s ability to digest food and pass stool is affected by a lack of roughage, grass may actually help their bodily functions run more smoothly.

So eating grass is just a way for them to make up for what they’re missing in their diet.

6. Your dog is suffering from some Medical Condition

Dogs can have a variety of GI problems, including gastric reflux, pancreatitis, and inflammatory bowel disease. If your dog is eating grass and exhibiting other symptoms such as a loss of appetite, decreased energy, diarrhoea, or constipation, it’s time to see your veterinarian.

How to Stop Your Dog From Eating Grass?

This isn’t a big deal if your dog eats grass on occasion. The most common reason for dogs eating grass is boredom or nutritional deficiency; if this is the case, simple routine and dietary changes can resolve the problem.

However, if your dog is eating grass, throwing up, or otherwise feeling ill, you should take the following steps:

  • You should feed your dog a well-balanced diet to ensure that he or she is getting enough nutrients for proper body functioning. Your dog may be eating grass due to a lack of fibre. To address this issue, feed your dog fiber-rich foods such as pumpkin, ground flaxseed, lettuce, apples, carrots, green beans, brown rice, strawberries, and blueberries.
  • You should exercise and train your dog to keep him physically and mentally stimulated. This will keep your dog from becoming bored. If your dog is not bored, he or she is less likely to eat unusual foods such as grass. Playing games like fetch and tug of war will physically stimulate your dog, while games like finding the treat and puzzles will mentally stimulate your dog.
  • You should take the treats with you when you go for a walk with your dog. You can use treats to distract your dog from eating grass. If you can keep them excited about getting a treat in exchange for performing a behaviour, you’ll keep their attention on you rather than the grass.
  • You can teach your dog the “NO” command to keep him from eating grass. Your dog will learn not to do certain things if you practise the command on a regular basis. When your dog obeys a command, you should always reward him with a treat or petting. Rewarding is the most effective way to accelerate the learning process.
  • You should avoid growing any toxic plants in your home. If you already have a toxic plant in your home, make sure to keep it out of reach of your dog.
  • If your dog is excessively chewing on the grass and throwing up, you should see a veterinarian right away. If the dog is eating more grass than usual, there could be an underlying medical condition. Most of the time, grass-eating isn’t a big deal. However, if it has become a compulsion or they appear sick, you should consult with your veterinarian.

Is it safe for my dog to eat grass?

Yes, grass is completely safe for dogs to eat. It does not always imply that something is wrong. Dogs eating grass is quite common (it has also been observed in wild dogs and may be completely natural), and grass does not usually cause too many problems. In fact, most veterinarians regard this as normal dog behaviour. However, this does not imply that you should allow your dog to freely eat grass from a field.


It is critical that you keep your dog away from grass in public parks and along roadsides—anywhere that may have been treated with chemical pesticides, herbicides, or exposed to environmental toxins and/or fertilisers.

However, if your dog is eating grass instead and throwing up all the time, you should consult with your veterinarian as soon as possible.

Final Thought

It is perfectly normal for a dog to eat grass, but you should keep an eye on what and where your dog is eating it.

Positive reinforcement training with a reward, exercise, and a well-balanced diet will all help.

As pet parents, we want our pets to be fit and healthy, so if you have any questions or concerns about your dog’s behaviour, you can freely consult your vet for the best advice.
