Ever noticed your pup nibbling on grass from time to time? While it may seem strange, dogs eating grass is actually quite a common behavior.

But why do dogs eat grass? Let’s take a look at the science behind this seemingly odd behavior.

Theories Behind Grass Eating Habits

There are a number of theories as to why dogs are drawn to grass-eating habits. Some experts believe that dogs may be naturally inclined to eat vegetation for various reasons, such as boredom or digestive issues.

Other experts argue that dogs are instinctively seeking out nutrients found in certain types of plants and grasses—similar to how wolves and wild canines supplement their diets with plant matter in the wild.

It is also possible that dogs eat grass simply because they like its taste or texture of it. Studies suggest that some types of plants may possess bitter compounds that help relieve nausea in dogs when they consume them.

This could explain why some pups seem to eat more grass when they’re feeling under the weather or have an upset stomach.

Is Eating Grass Dangerous?

Fortunately, eating grass is generally not harmful to most healthy adult dogs; however, there are potential risks associated with consuming too much vegetation, including choking hazards, bacterial contamination, pesticide exposure, and parasites.

If you notice your pup eating large amounts of grass or ingesting toxic plants, make sure you contact your veterinarian right away for advice on how to proceed safely.


In conclusion, there’s still no definitive answer as to why exactly dogs like eating grass so much—it could be due to any combination of factors we discussed above.

That said, as long as your pup only eats small amounts of non-toxic vegetation and has no known health problems related to their habit, there’s no need for concern!
