This is a subject that will yield a different opinion from everyone that you ask. There are some excellent dog foods on the market we can give you some suggestions, but bottom line is getting a high quality puppy food and see if your puppy does well on it. We suggest you do not go hoping around from one food to another. If you find a quality food that your puppy enjoys, and he is doing well on it, stay with that food.  It is our recommendation that you keep your puppy on a Puppy food till at least 12 Months of age before you put your dog on adult food again a high quality adult food.
