Why Do Dog’s Eat Grass?

Have you ever taken your dog out for a potty break and turned your back, only to discover them
chomping on a large mouthful of grass? While you might panic and think about the vomit you’ll be
cleaning off the carpet later on, this behavior is not always cause for alarm. But why do they do it and
how do you know when it is actually a problem?

Some dog owners and veterinarians assume that grass eating is a form of pica, or eating strange items,
sometimes caused by a diet deficiency. Many diet deficiencies are rooted in missing vitamins, nutrients,
or minerals that are absent from daily intake. For example, it could be your dog’s way of getting more
fiber, which helps them pass gas and stools, and also assists other bodily functions.

But if a dog’s diet is complete and balanced, eating grass may not be related to a deficiency at all—it
might actually be instinct. Dogs’ digestive systems, dietary needs, and cravings have evolved to fit the
lifestyle of domesticated dogs. While canines in the wild weren’t getting their primary source of nutrients from grass, eating an entire animal provided an optimal diet, especially if the animal’s diet consisted of various plants. Dogs are omnivores and naturally crave the act of eating grass as part of their genetic makeup, dating back to when they hunted their own prey. Of course, they might also just enjoy the taste and texture of grass in their mouths, especially when new grass is emerging for the first time during spring.

Is Eating Grass Bad For Dogs?
The consumption of grass can be a sign that your dog is attempting to relieve an upset stomach and
some pups do vomit soon after eating it. That said, fewer than 25 percent of dogs actually vomit from
eating grass and only 10 percent show signs of illness prior to eating grass, meaning most are not likely
eating it because they’re sick. But while it’s not typically harmful for dogs, eating grass can cause
intestinal parasites that are easily picked up from animal droppings and stool. It’s also important to note that the herbicides and pesticides sprayed on your lawn can be harmful to your pup.

When Should You Take Action?
If you notice them eating grass more frequently or excessively, be alert of potential underlying illnesses that your dog is attempting to self-treat. Also look for vomiting, diarrhea, weight loss, decrease in appetite, blood in stool, lethargy, or lip licking.

Why Do Dogs Eat Grass?
Always monitor your dog when there are house plants nearby, as certain varieties can cause toxicity if
they’re chewed or ingested. While chewing on the lawn is a common behavioral action in many canines,
you can train your dog out of the behavior to help provide peace of mind.

It’s always best to consult with your vet if you think your dog has chewed on a toxic house plant or
possibly ingested too much grass orsmall amounts of chemicals. The vet will be able to perform
assessmentslike fecalsamples, blood tests, or even physical examsto determine underlying conditions.
If your dog doesn’t exhibit any symptoms, but you feel that they may have ingested too much grass,
keep them hydrated and allow time for potty breaks. Have your dog fast 8-12 hours before introducing
food slowly. After 12 hoursif your dog continuesto show signs, check in with your veterinarian
