Why Do Dogs Eat Grass: Reason And Solution

Why Do Dogs Eat Grass

Why Do Dogs Eat Grass-You might have noticed that dogs sometimes eat grass. But have you ever wondered why they do that? If you have a dog or you like dogs, it’s good to know about this. Dogs usually eat things like meat, milk, eggs, and even the food we eat. So, when a dog eats grass, it might seem strange. Let me explain Why Dogs Eat Grass.

Why Do Dogs Eat Grass?

Dogs eat grass for different reasons, but we don’t know all of them for sure. Some ideas are popular, but they haven’t been proven by studies. Here are some common reasons people think, along with where these ideas come from.

Dietary deficiency

Some people who have dogs and veterinarians think that when dogs eat grass, it looks like they have a disease called pica. This means that they eat things that are not food. They think this may be because dogs are missing some important things in their diet. But studies have not found any proof of this. In fact, most grass-fed dogs are already getting enough food and are in good health.

Fiber Need

When dogs eat grass, it’s like they’re eating something healthy for their tummies. The grass has something called fiber, which is like a helper for their tummies. It helps them digest food, go potty, and keeps their tummy system working well. There was a story about a small poodle that ate grass and threw up every day for a long time. But when the poodle started eating food with lots of fiber, it stopped throwing up grass.


Some scientists think that when dogs eat grass, it’s something they naturally do because their ancestors were wolves. Wolves and wild dogs also ate grass and plants. This might have been about 2-10% of their stomach contents. The grass could have given them useful things like vitamins, minerals, antioxidants, or things to fight parasites.


Some people think that dogs eat grass because it might help their tummies feel better. Like when we take medicine for a tummy ache, grass could work like natural medicine for dogs. It might help if a dog’s tummy is too acidic or inflamed. But we don’t have strong proof for this yet. Also, most dogs that eat grass don’t seem sick before or after eating it.


Eating grass can also be a sign of boredom or stress for some dogs. Dogs who are left alone for long periods of time, have limited stimulation, or lack exercise may resort to eating grass as a way to cope or entertain themselves. Providing your dog with more toys, games, walks or attention may help reduce this behavior.

Tasty food

Finally, some dogs may enjoy the taste or texture of grass1. The grass may provide a different taste or sensation than their regular food, or it may satisfy their natural curiosity about the environment. As long as the hay is not contaminated with pesticides, fertilizers, or other harmful substances, eating limited amounts of hay is unlikely to harm your dog.

How can I prevent my dog from eating grass?

There are many reasons why your dog might eat grass. It could be because they need something missing in their food, like certain vitamins. Sometimes, they might just want more fiber in their diet. Dogs also have a natural instinct to eat things. Other times, their tummy might feel upset, and eating grass can help soothe it like medicine. Boredom could be a reason too. And of course, if the grass tastes good, they might eat it.

But you have to be careful. If the grass has bad stuff on it like chemicals or things that can make your dog sick, then eating grass is not good. So, if you don’t want your dog to eat grass, that makes sense.

Here are some tips that can help you stop your dog from eating grass:

Change Food

Give your dog special food that has good things for them. This food has stuff like fiber and vitamins that dogs need. Also, let them eat veggies like cooked carrots. It’s like a treat and helps them feel better.

Dog Plant

Give your dog their own plant to eat, like burdock or peppermint. This is safe and stops them from eating bad grass.

Play Time

Play with your dog using toys, games, or walks. This helps them not feel bored or worried, so they won’t eat grass.


Teach your dog to stay away from grass. If they do this, you can give them tasty treats.

Spray Smell

Spray a smell that dogs don’t like on the grass. Things like vinegar or lemon juice. This makes the grass not yummy for them. But be careful not to spray stuff on plants that you like, or that might hurt your dog.

What are the effects of a dog eating grass?

The effects of eating grass on dogs can vary depending on the amount, frequency and type of grass they consume. Some possible effects are:

No Effect

Some dogs can eat grass occasionally or regularly without any noticeable problems. They may simply enjoy the taste or texture of grass, or they may have a natural instinct to graze on plants.


Sometimes, if a dog doesn’t feel good or eats something bad, they might eat grass to make themselves throw up. But not all dogs that eat grass throw up. If a dog throws up a lot or often, it could mean they have other health issues like a tummy problem, bugs inside them, or they ate something dangerous. If your dog throws up a lot after eating grass, it’s best to talk to a vet who knows about animals.

Gastrointestinal irritation

If a dog eats lots of grass or grass with bad stuff on it, their tummy can get upset. This might make them feel bad, with problems like runny poop, tummy ache, gas, and feeling puffy. To stop this, make sure your dog doesn’t eat grass that was sprayed with chemicals or is unsafe. Give them clean water and good food to eat.

Fiber intake

Eating grass gives dogs fiber, which helps their tummy and poop. Some dogs eat grass because they need this fiber. But you shouldn’t only give them grass for fiber. It might not be enough. Instead, pick good dog food with the right fiber for your dog’s size and age. That’s better for them.

Nutritional deficiencies

If your dog eats a lot of grass, it could mean that they aren’t getting enough vitamins or minerals. This can happen when they don’t eat well or when they have a health problem. Ask a vet to check if you think your dog is missing any of these things. They can help figure out the reason. Also, feed your dog better food that has all the nutrients it needs.

Boredom or stress

Grass eating can also be a sign of boredom or stress for some dogs. Dogs that are left alone for long periods of time, have limited stimulation or lack exercise may resort to eating grass as a way to cope or entertain themselves. To prevent this, you should give your dog more toys, games, walks, or attention. You should also pay attention to any sources of stress or anxiety that may be affecting your dog’s well-being.”

I hope these tips help you and your dog. Remember to always consult your veterinarian if you have any concerns about your dog’s health or behavior.
