Hmmm, I would go with Wellness. I would do a combination of wet and dry food, I might even add a splash of water. I respectfully disagree with your breeder, I would not free feed. I would give a puppy 3 or 4 small meals per day, by the time the pup is 6-7 months old I would be feeding 2 meals per day, measured amounts. Maybe an occasional bite for a snack for training purposes.
