Why Does My Dog Eat Grass?

Have you ever wondered Why Does My Dog Eat Grass? Over 75% of dog owners report they have caught their dog eating grass at some point.

Pica is the scientific term used to describe when dogs (or even humans) eat things that are not food, regularly. Pica is defined as “a tendency to eat substances other than normal food.” Now the question is, why?! This is a common debate and although there is not just one answer, it’s typically not a sign of anything serious. Possibilities include boredom, anxiety, lack of fiber, intestinal worms, gastric reflux or upset stomach. It’s best to check with your veterinarian if you dog is eating grass enough to cause you concern or if there are any other symptoms such as changes to their water intake or appetite for their regular food, or signs of discomfort.

Is it safe for my dog to eat grass?

For most dogs, eating grass is not a big concern. The most common conclusion turns out to be boredom. In general it’s not a health risk for your dog to digest grass, do be cautious and aware that any herbicides or pesticides sprayed on grass can be toxic for your dog. Also, when chewing and chomping up the grass from the ground, your dog could ingest intestinal parasites such as hookworms or roundworms. If you suspect internal parasites, try products like Nemacor Maxx 4 which is a broad treatment for multiple types of worms. Contamination in the grass comes through fecal residue from other dogs droppings. Sometimes a dog may eat grass due to having an upset stomach or lack of fiber in their diet. Typically for reasons of an upset stomach, it wouldn’t seem chronic. Products like NaturVet Coprophagia Stool Eating Deterrent, helps your dog fight the urge to eat their stool, if you’re concerned that might be contributing to their grass consumption.

How to Stop Your Dog From Eating Grass

No matter the reason that’s causing your pooch to eat grass, it isn’t the ideal snack. Dogs who are motivated by food or dog treats can be re-directed to a healthier alternative for a snack.


If you believe your dog is eating grass because they are bored or stressed, a great first step would be to increase the amount of exercise they are getting. Encourage them with some fun activities or toys. This can be a simple game of frisbee or investing in a new sturdy chew toy to keep them occupied.

Change Food

Dogs can exhibit this unwanted behavior due to a nutritional deficiency. Switching to a higher quality dog food can help deter the problem. Consider a dog food formula with higher fiber.

Redirect Training

You can also train and redirect your dogs attention with treats or praise by accompanying them outdoors. You can deter the behavior with distractions and reward them for not keeping their nose off the ground.

We hope the suggestions above help alleviate your concerns about grass eating and give you ideas to combat this issue with your furry friend.
