You don't have enough room to take him outside? I don't understand that part.

I will say that paper training sometimes causes problems. Such as, you can never leave a newspaper or anything similar laying on the floor for the rest of the pup's life, or it may be made into a toilet Are you paper training because you're not home a lot? I would strongly suggest just training him to go outside. He's an older puppy so he won't have to go outside as frequently as a baby.

Please don't let your husband turn him into a backyard doggie
