  • Potentially harmful fertilizers, herbicides and pesticides – When your dog starts eating grass, make sure it’s in an area that wasn’t recently treated with chemicals. Consult your veterinarian about what lawn treatments are toxic and what to do if your dog ingests any treated grass or plants. 
  • Ingestion of more than just grass - While eating grass is okay, be make sure your dog isn’t eating things that can be unhealthy or cause digestive blockages like, rocks, leaves, sticks and, yes, even poop
  • An underlying health issue – Eating grass can be a symptom of a potential health issue, in conjunction with other clinical signs such as diarrhea, weight loss, lethargy and vomiting.

Purina behaviorist Dr. Annie Valuska recommends incorporating a “leave it” command into your training, to stop your dog from eating grass (or anything else they are not supposed to have).
