Origins of behavior

An ancestral habit

Dogs' ancestors, wolves, had a varied diet that included not only meat but also plants, fruits, berries and grass. It is therefore possible that our dogs have inherited this attraction to grass.

Food craving

Some dogs may simply like the taste of grass. This phenomenon, called “food craving,” refers to an intense need or desire to consume a certain food. If your dog only eats grass occasionally, there is usually no cause for concern.

Underlying health conditions

A dog that frequently eats grass could suffer from health problems such as kidney or liver problems or parasitic infestations. In such cases, veterinary consultation is essential.
