Why do dogs eat grass?

Answer: Instinct to induce vomiting

Dogs confuse grass with meat — Wrong. Dogs distinguish grass from meat. Grass-eating is deliberate behavior—often to relieve stomach discomfort or induce vomiting.

Instinct to induce vomiting ✓ — Correct! Self-medication behavior! Dogs eat grass for multiple reasons: (1) Digestive upset—induces vomiting to expel irritants. (2) Dietary fiber—helps move intestinal contents. (3) Instinctive behavior—inherited from wild ancestors. (4) Boredom/anxiety—behavioral comfort. Not harmful unless grass treated with pesticides. Wolves/wild canids also eat grass and plants. If frequent, may indicate diet deficiency or GI issues—vet checkup recommended. Normal occasional behavior!

Sharpens teeth on grass blades — Wrong. Grass doesn't sharpen teeth—chewing bones does. Dogs eat grass for digestive relief, inducing vomiting, or adding fiber to diet.
