There are many different reasons for which your dog might eat grass, and, in some cases, the reason may not be obvious. One of the most common theories out there is that dogs eat grass when they don’t feel well as a way of making themselves vomit so they feel better. Evidence suggests, however, that most dogs who eat grass aren’t actually unwell before eating the grass and only 25% of dogs who eat grass regularly vomit afterward.

Another potential concern with your dog eating grass is the likelihood that he’ll be exposed to pesticides and herbicides. The chemicals used in lawn treatment can be extremely toxic to dogs, especially when ingested. Your dog is also at risk for ingesting other harmful plants along with the grass if he’s munching indiscriminately. If you’re worried about it, consider growing a tray of grass at home for those moments when your dog simply wants to much.
If your dog occasionally takes a bit of grass on his daily walk, it probably isn’t anything to be concerned out. However, if your dog suddenly starts eating a lot of grass, or if he vomits after doing so, you might want to check with your veterinarian just to be sure. When it comes to your dog’s health and safety, you can never be too cautious.
