I have had my little guy for about a month now and he is 2 years old. I have brought him to the vet for his update shots but since i had gotten him he eats alot of grass and gags a lot and sometimes blows chunks. I did change his food when i had gotten him but he never has had the runs and he drinks and eats just fine. He is on flea meds and is a clean loved dog that has no way of getting into anything bad. Does anyone have any idea what could be wrong with my little enzo?
