Why Do Dogs Eat Grass?

June 1, 2020

Why do dogs eat grass?It’s summer and the grass is green in most parts of the nation. Have you noticed your dog eating grass? Or possibly you see it at the other end, when picking up doggie doo. Maybe like me, you wondered why your dog would eat grass to begin with. Here are some myths and realities about this behavior.

Myth #1: Your dog is sick

This is simply not true. In fact, according to PetMD, less than 10% of dogs who have a symptom of eating grass are found to be sick by a veterinarian. It seems there are additional myths out there assuming dogs eat grass to throw up to heal an upset stomach. Again, this is false. Grass does not make your dog throw up and your dog is not sick because they eat grass.

Myth #2: Your dog is bored

If your dog is outside for long periods of time, they may sleep if they are bored. But for the most part, they will not eat grass. To avoid boredom, be sure to have plenty of things to do when outside such as playing Frisbee with them and being outside to play catch or run with them. For summer activities, add a kiddie pool this summer to cool them down. If you have plenty of chew toys inside, throw a couple outside to see if he plays with them.

Myth #3: Your dog has some sort of nutritional imbalance

Some say your dog is asking for more fiber when they eat grass. This is hard to prove, but if you want to examine if this is the case for your dog, consider switching to a high-fiber dog food variety. If you notice less grass eating, this may be the case. However, most say this does not change the grass eating habit of their dog when they do this.


Most veterinarians consider dogs eating grass as a common behavior. It has been observed with dogs in the wild as well. In a small scale study, dogs were found to eat grass because they enjoy the taste. Does your dog enjoy vegetables? If your dog is like mine and likes carrots and celery, maybe they enjoy the taste of grass as an additional vegetable in their diet.

The real truth: dogs are pretty smart and don’t eat or things that may harm or hurt them. Score one more point for the dogs!
