So my boyfriend said my 5 mo old aus shepherd needed a friend and I agreed. He told me he wanted a pit bull puppy. I said a puppy would be ok since he would grow with my aussie. Well he came home with a 9 month old pitbull!!!! The "puppy" is already 45 pounds and my dooney is only 25!!!! He is upset that I will not allow his dog the same house set up as Dooney has (which is a crate that has the door up to the doggy door so she can come inside if she gets hot. He thinks I am being unreasonable. However, the puppy although only playing is far too rough for my aussie. What do I do?????????
