Understanding Your Dog’s Behavior

The reasons can vary from dietary needs to dealing with an upset stomach. But don’t worry, they’re not turning into little lawn mowers.

Possible Reasons Why Your Dog Eats Grass

  1. Nutritional Needs: Dogs, unlike their feline counterparts, are not strictly carnivorous. They may eat grass to supplement their diet with fiber or other nutrients they are lacking.
  2. Stomach Upset: Your dog might be eating grass to induce vomiting when they’re feeling unwell.
  3. Boredom: Yes, your dog could be eating grass out of sheer boredom. Dogs need stimulation, and if playtime or walks are lacking, they may resort to this behavior.
