Hello how may I help you? Can you answer a pet food question for me? I sure can! What kind of pet? It's my dog Rex. I really don't know how much I should be feeding him each day. I don't know how much I need for an entire week. It would be even more helpful to know what breed of dog Rex is. He is a Scottish Terrier. Great. Is he a puppy or adult dog? He is just about 1 year old. Okay. I believe 15 pounds of dog food a week would be enough. That's quite a bit of food for a little dog. Should I really be feeding him that much? You will have extra left over for the next week.
