Why Dogs Eat Grass?

Most dog owners have seen their dog eat grass. So, why dogs eat grass?

You might even feel confused when you see them doing that and get worried about it, ask yourself: Is he hungry? Is he Bored? Is he Sick? Will eating grass hurt him?

But eating grass it’s actually a very normal behaviour, so let’s understand why dogs eat grass.


Some dogs eat grass simply because they like the taste and texture. Other dogs tend to eat grass when their stomach is upset or gassy. The grass helps induce vomiting in order to expel whatever might be bothering your dog.

Why Is My Dog Eating Grass?

There are a variety of reasons why your dog is eating your grass.

Some people propose that dogs might turn to eat grass when they don’t feel well as a way to make themselves vomit, and then feel better. Others dispute this idea, on the basis that dogs are not proven to be smart enough to decide to treat an upset stomach by eating grass.

Evidence suggests that most dogs that eat grass aren’t unwell beforehand, or at least they don’t seem so. In fact, fewer than 10% of dogs seem to be sick before eating grass, according to their owners. And grass-eating doesn’t usually lead to throwing up – less than 25% of dogs that eat grass vomit regularly after grazing.

Other suggested reasons why your dog might be eating grass include improving digestion, treating intestinal worms, or fulfilling some unmet nutritional need, including the need for fibre. One published study reports on a miniature poodle that ate grass and then vomited every day for seven years. Three days after putting the dog on a high-fibre diet, the owner reported that the dog stopped eating grass entirely. And, of course, there is also the possibility that your dog simply likes the way grass tastes or feels.

Is it harmful to my dog?

Even though it is a normal behaviour and grass will not harm them, you still need to mindful of chemicals used on grass that may irritate your dog’s stomach or cause health problems.

When gardening at home, be sure to look out for products that are safe for use around animals or keep your dog away from areas where non-safe products may have been used.
