If you have ever asked “why does my dog eat grass?”, you are in good company. Grass eating is common in dogs and is often harmless, but it can sometimes point to boredom, dietary gaps or an upset stomach.
Common reasons dogs eat grass
Many dogs simply seem to enjoy the taste and texture of grass, especially young, fresh blades.
Some dogs graze out of boredom, anxiety or to get attention from their owners.
Dogs may eat grass when they feel nauseated, and some vomit afterwards, though most grass eaters do not vomit.
Is it normal for dogs to eat grass?
Occasional grazing in an otherwise healthy, current-on-prevention dog is generally considered normal behavior. Veterinary sources note that the cause is not fully understood and that there is probably more than one explanation.
When grass eating can be a problem
Grass treated with herbicides, pesticides or fertilizers can be toxic, and grazing can expose dogs to intestinal parasites from contaminated soil.
- Frequent, compulsive grass eating
- Repeated vomiting, diarrhea or loss of appetite
- Lethargy or abdominal discomfort
How to reduce grass eating
Offer regular exercise, puzzle toys and training, review the diet with your vet, and keep your dog away from lawns that may have been chemically treated.
