Many pet parents get confused when they see their dog eating grass and wonder if the tendency is natural. As it turns out, dogs eating grass is relatively common behavior. Let’s delve a little deeper into the occurrence, and learn about the several theories as to why they do it:

Some experts believe that dogs eat grass as a natural instinct inherited from their wild ancestors. Wild canines would consume vegetation as part of their diet, which could include grasses, herbs, and other plants.

Dogs may eat grass to induce vomiting or aid in digestion. When they have an upset stomach, they may instinctively seek out grass to help them vomit and relieve discomfort. The grass may help them expel something irritating or indigestible from their stomachs.

In some cases, dogs may eat grass if they have a nutritional deficiency. They may be trying to supplement their diet with nutrients that they are lacking, such as fiber or certain vitamins.

Dogs may eat grass out of boredom or anxiety. Similar to other repetitive behaviors seen in dogs, such as excessive licking or chewing, eating grass may be a way for them to alleviate stress or occupy themselves.

Dogs are naturally curious animals, and they may simply be exploring their environment when they eat grass. They use their mouths to investigate objects, textures, and tastes, and grass may be one of the things they are curious about.

Some dogs may simply enjoy the taste or texture of grass. It’s possible that they find it refreshing or satisfying to chew on grass, similar to how humans might enjoy chewing gum or other non-food items.

Eating grass could be an instinctual behavior related to self-medication. Some experts believe that dogs may eat certain plants, including grass, to help expel intestinal parasites or toxins from their system.
