Why Does My Dog Keep Eating Grass?

So weird.

Dog eating grass

Have you ever been walking with your dog when she suddenly stops to tear a chunk of grass out of the ground to munch on?

So many questions might run through your head:

“WTF is she doing!?”
“Why is my dog eating grass?”
“Should I stop her?”

You might have heard that dogs eat grass to make themselves vomit, or to make up for some sort of nutritional deficiency. But to stop you from worrying, here are some insights from a New York City veterinarian — who assured us that this is pretty normal.

“Grass or plant eating is a widely recognized normal behavior amongst domestic dogs,” Dr. Stephanie Austin, a veterinarian at Bond Vet, told The Dodo. 

According to Dr. Austin, grazing shouldn’t cause any alarm for dog parents.

“Rarely does this cause problems and rarely is it indicative of any problems,” Dr. Austin said. “Often the dog is just having fun.”

Does eating grass hurt my dog?

While there is an old wives’ tale that some animals try to make themselves sick by eating grass, Dr. Austin said the stories don’t hold up.

“The only time we’re concerned is if a pet ingests a plant that is potentially toxic to them,” Dr. Austin said. And since some toxic plants can be hidden in grass, it’s good to know what to look for. Common toxic plants include:

- Aloe
- Calla Lily
- Chamomile
- Daisy
- Eucalyptus
- Geranium
- Holly
- Needlepoint Ivy
- Oregano
- Poinsettia

So in general, there’s no need to be concerned when your dog eats grass. Just keep in mind that if she does swallow a bunch at one time, she might vomit from nothing more than a bellyache.
