Hello how may I help you? I have a question about feeding my dog. Sure, what kind of dog do you have? It's a basset hound puppy. Great! What is your question? How much dog food should I be using in a week? You should feed a basset hound puppy 2 cups a day so 14 cups a week I guess the entire 20 pound bag each week is a little bit too much? Yes, that is way too much Maybe that's why he seems so lethargic? That is definitely a possibility. Be sure to visit your vet however if you feel there may be a problem
