My dog eats grass and vomits. Is this a health issue or just behavior?

Updated On September 23rd, 2025

My dad’s dog, Némó, a 10 year old male Hungarian Vizsla always eats grass. Sometimes he vomits it up, but he is constantly sating grass and has been for the past few years. Could it be a health problem? Or just behavioural?

It could be either - some dogs with gastrointestinal disease will eat grass and the occasional vomiting could be a sign of nausea. It’s also possible that this is simply a preference that Otis has. I would recommend having him examined by a vet to make sure there is no concern for a gastrointestinal problem. They might recommend checking blood work as well.
