Is eating grass normal or abnormal for your pet ??

I have had people tell me that when they eat grass it can be a sign of worms, parvo or some other intestinal or digestive problem. However, my vet laughed that off sort of and said that it's actually very common for them to graze or snack on it occaisionally and as long as there are no present symptoms of another issue or they seem fine, it's not anything to worry about.
