Interestingly, grass eating is also tied to canine ancestry. Wild canines often consumed grasses and plants found in the stomachs of their prey, which helped balance their diets with fiber. Domestic dogs have retained some of these instincts, but today, psychological triggers such as boredom and anxiety primarily drive this behavior.

Some dogs eat grass when their stomach is unsettled because the irritation triggers vomiting and provides relief. Others do it out of boredom, habit, or mild anxiety.

Anxiety and stress relief are another possible reason for this behavior. Dogs, especially those with separation anxiety or other emotional issues, might eat grass as a way to calm themselves down.
