Q. What is the best food brand to give my Yorkie (currently a puppy)
A. Or Purina but the main thing is to make sure that what ever good your puppy eats is agreeing with him and not cause any vomiting or diarrhea. Try a small bag of food in what you want to try that way your not invested in a huge bag until you know it is a proper fit.
A. Most brands are good. Main thing u want to loo for in any pet food is the nutrition index. With a puppy u just want to make sure that he is happy eating the food, if he doesn't like it then you should switch, and that it doesn't cause any gastro intestinal upset or irregularity. The main ones that any vet will recommend are science diet/hills, royal canin
