He has a doghouse and blankets but he won't sleep in the doghouse he just drags everything out and lay outside. I have a shed but I have two other dogs who are smaller in kennels. He's my roommate's dog and he won't let me put him inside with the other two dogs(that are also his). I need to be able to prove to him that the dog is cold. Because I feel bad for him. I have bought blankets for all of them. He says "dogs don't get cold"
