Why do dogs eat grass? Surprising reasons and tips


Dogs are known for their curious appetite, and one of the mysterious things they do is eating grass. But have you ever wondered why they do it? Eating grass is a common behavior among dogs, and it can have various reasons behind it. In this article, we’ll explore some of the surprising reasons why dogs eat grass and provide tips for pet owners to keep their furry friends safe.

Reasons Why Dogs Eat Grass

Digestive Issues

One of the most common reasons why dogs eat grass is to relieve digestive problems. When a dog’s stomach is upset, they may try to induce vomiting by eating grass. Grass can act as a natural emetic, causing the dog to vomit and expel whatever is causing their stomach discomfort.

Nutrient Deficiency

Another reason why dogs eat grass is that they may be lacking essential nutrients in their diet. Grass contains fiber, and some dogs may eat it to supplement their diet with this nutrient. Additionally, some dogs may crave fresh greens, which are a natural source of vitamins and minerals.

Boredom or Anxiety

Dogs who are bored or anxious may resort to eating grass as a way to occupy themselves or relieve stress. This behavior is usually harmless and can be resolved by providing more exercise, mental stimulation, or affection.

Natural Instinct

Lastly, eating grass could be a natural instinct for dogs. Dogs are descended from wolves, who ate grass as part of their diet to aid digestion and obtain nutrients. Although today’s dogs are domesticated, their wild instincts may still drive them to eat grass.

Risks of Eating Grass

While eating grass is not harmful in itself, there are some risks associated with it. Dogs may ingest harmful substances, such as pesticides or fertilizers, that are used on the grass. Additionally, some plants are toxic to dogs and can cause severe health problems if ingested.

Tips for Pet Owners

If your dog eats grass, there are some things you can do to keep them safe:

  • Supervise your dog when they are outside to prevent them from eating potentially harmful plants or grass that has been treated with chemicals
  • Make sure your dog’s diet is balanced and provides all the necessary nutrients
  • Provide your dog with plenty of exercise, mental stimulation, and affection to alleviate boredom or anxiety
  • Talk to your vet if your dog has frequent digestive problems or eats grass excessively


In conclusion, eating grass is a common behavior in dogs that can have various reasons behind it. While it’s usually harmless, pet owners should be aware of the risks associated with it and take steps to keep their dogs safe. By understanding why dogs eat grass and providing them with a healthy and safe environment, we can ensure that our furry friends stay happy and healthy.
