You’re playing with your pup and they stop to eat grass—again. A quick look around the park, and you notice another doggo is doing the same thing. What’s the deal? Before you deem this as a cause for concern, here’s what researchers currently know about why dogs eat grass, and more importantly, if it’s safe.

Why Dogs Eat Grass

There’s an old theory that eating grass may be a sign that your dog’s diet is missing certain nutrients. However, lots of researchers say this isn’t the case. After all, almost all dogs eat grass sometimes, even the ones on well-balanced diets.

Commercial dog foods that contain the phrase “complete and balanced” should give your dog all the nutrients they need. Just make sure you are feeding them the right food for their age and size. For example, a puppy should receive food that’s designated for puppies, and a senior dog should get food that’s meant for seniors. These are adjusted for the nutritional needs of the life stages.

Anyway, it’s hard to know for sure why dogs eat grass, but the leading theories include:

  • Liking the taste and texture
  • Craving the “roughage” of grass that is rich in fiber
  • Boredom
  • Trying to get your attention by doing something “naughty”

Should You Worry?

You don’t usually need to be concerned if your dog is eating grass. The exception is if the habit is causing them to vomit, or if it’s combined with other symptoms like:

  • Weight loss
  • Bloody stool
  • Lethargy

Grass itself isn’t “bad” for your pupper, unless Rover is eating it in excessive amounts, or if you’ve recently sprayed the lawn with weedkiller or pesticides. If you know your dog regularly eats grass, you might want to avoid using pesticides on your lawn just to be on the safe side.

If you’re still concerned about your dog’s grassy diet and its potential effect on their health, check in with your veterinarian. (Speaking of a healthy diet, here are human foods you shouldn't feed your dog.)
