He is on purina pro plan for puppies.
Any particular reason for choosing this food? Its an ok food, but still contains corn and corn products pretty high in the ingredient list. Corn does have some benefit, protein and fiber, but more often than not is used as a filler. I know a lot of dogs do just fine on Pro Plan, but do be vigilant of skin, coat, bowel and apetite issues. Smooth coat dogs and many pure bred dogs seem to have higher instances of sensitivities to food ingrediants than many mixed breed dogs in my own observations. I manage a pet food store and talk to as well as see LOTS of dogs and issues every day. Sadly, most people are more apt to come to a store like mine to fix issues with their dog than go see a vet, I always recommend they do and preface all my recommendations with "I'm not a vet or RVT, but..." Again, its far and away better than Dog Chow or other commercial foods, but there is a whole 'nother world of premium and ultra premium diets out there that can save money over lesser foods and future vet bills.
I have owned working/hunting dogs my whole life, my two now are mixed breed rescues (not enough time to do justice to a hunting dog nowadays), have bred dogs and been involved with family members who have been breeding dogs for 40+ years.
I am up to date one most dog foods and how they compare to each other, also how each facet the complex needs of dogs relate to features of most foods, so if you have any questions feel free to ask, but remember, I am not a vet or RVT, I can just help you wade through all the marketing hype and confusing information out there about dog food.
Again, great looking pup!
