It’s a question that only you can answer, because you are the only one who is in a position to gauge, on a daily, monthly, and yearly basis, how your dog responds to what you feed him.

That said, we can give you some tips to guide you into the right section of your local pet supply store – that is, past the lowest-cost, lowest-quality foods; past the higher-cost but still low-quality posers; and into the area where the top-quality foods are found. Take note: They are expensive, perhaps prohibitively so, especially for families with several large dogs to feed. But you can’t expect to pay hamburger prices for filet mignon, and it’s the quality (and thus price) of the ingredients that set the top-quality foods apart.
