Why do dogs eat grass?

Dogs and puppies like to eat things, and outdoor items are no exception. Naturally, your best friend likes to snack on various things, but why grass? Nold points out some reasons why your dog may eat grass.

“There are many theories of why dogs eat grass including boredom, a dietary deficiency, and to help ease an upset stomach by stimulation of vomiting. However, I think in most cases dogs eat grass just because they like it.”

Every dog is different and some may like grass more than others. Whether you have a puppy, adult dog, or senior, at one point during their life they may attempt to snack on the grass. Just make sure to monitor them when they’re outside.

Is it common for dogs to eat grass?

Puppies are curious. It’s not surprising for your new best friend to explore their new space, including what’s in their backyard. So, of course, they may want to try grass. In fact, “eating grass is a normal behavior for a dog,” says Nold.

Also, this was supported by a study from 2008 (Appl Anim Behav Sci. May 2008; 111(1-2):120-132) which found “68% of dogs were reported to eat plants on a daily or weekly basis with the remainder eating plants once a month or less. The grass was the most frequently eaten plant by 79% of dogs. Only 9% were reported to frequently appear ill before eating plants and only 22% were reported to frequently vomit afterward.”
