Hello how may I help you? I have a golden retriever puppy. Great! Do you have a question? How much food will it eat in a week? Do you feed canned food or dry food? Dry food. Are you feeding a puppy chow? I'm feeding him puppy food. You should figure on one 20 ounce bag a week. Should I get my puppy dog treats as well? Yes, your puppy will enjoy that.
