Dogs eat grass for various reasons. Sometimes it’s just a simple matter of curiosity or boredom. Other times, they might eat grass when they have an upset stomach to help themselves vomit. Some experts suggest it could be due to dietary deficiencies, seeking more fiber in their diet. In my experience, dogs often exhibit this behavior when they aren’t feeling well or when they need to balance their digestive system. If this becomes frequent or leads to health concerns, consulting a vet is crucial. In general, occasional grass nibbling isn’t unusual, but persistent behavior might need attention.
