Thankfully my senior pup who is also 13 was paper trained at a pup and when he got older and can no longer hold it in throughout the night he will use the papers. I don't know how easy it will be to train a pup who has no experience with pad/paper training will be, its worth a try. You are welcome to check out my web site with the instructions that I give all my new owners and how I myself have successfully paper trained all of my pups.
