7 Common Reason your Dog is Eating Grass

Upset Stomach

You may have heard many people say that dogs and cats eat grass when they have an upset stomach. Although there is no medical evidence to support this claim, many vets and pet owners agree with it. The grass may help your dog settle an upset stomach and relieve pain by acting as an antacid that may calm your dog.

Remember that eating grass may not actually help your dog and may indicate some other problem with your canine friend.

Dietary Needs (Fiber Dose)

The grass is rich in dietary fiber. As you all know, fiber helps soothe the stomach and induce healthy bowel movements. So, your dog may eat grass fanatically just to pass stool. If so, consider increasing fiber-rich foods in your dog’s diet.


Pica is a medical condition characterized by the urge to eat non-edible items such as paper, clothes, rocks, dirt, and grass.

It may look like normal behavior, but eating non-edible items can lead to nutritional problems, bloating, and stomach issues. Pica is usually reported in adolescent and adult dogs and doesn’t go away after some time. Take your dog to a vet immediately if eating non-edible items becomes obsessive.

Pups may also eat non-food stuff, but it is completely normal because they explore the world around them and love to munch on everything they can grasp.


Stress, anxiety, and boredom often account for irregular dog behavior like eating grass, chasing tails, and licking paws.

Take your dog out for a walk, play with him, treat him with special foods & toys, and show affection. Dogs like to play, wander around and enjoy themselves. Keeping them confined can build up negative energy and they’ll manifest it in different ways.

Enjoying a Special Treat

Your dog may like a special treat in the shape of grass. If your dog eats grass calmly (grazing) in small amounts and doesn’t get ill, there is nothing to worry about. He just loves it. Relax and let him fulfill his appetite.

Your dog is Thirsty

Dogs may eat grass early morning or evening to quench their thirst. There is a lot of dew on the grass during this time, and they eat it for water. You can avoid this by keeping your dog well-hydrated.


Your dog may eat grass out of instinct. Dogs used to roam the wilderness and ate whatever they like before they were made pets and put to use by humans.

You can do nothing to stop them if they are eating grass out of instinct. Let them eat it but supervise, so they don’t eat anything harmful or fall ill.
