I have a 7 month old pitbull american bulldog puppy who is being very difficult to housebreak and crate train. He doesn't seem to want to alert us to when he needs to go out he would rather just go where he is at (be it in his crate or in the kitchen). He doesn't seem to be able to hold it long either he can only hold it for an hour or so before he has to go. The breeders we got him from did not work on housebreaking and I don't think that they worked on crate training him either. I asked the vet if it could be medical and he didn't think that it was. He said that we just need to get him to expand his bladder. Has anyone else had the problem or a dog that won't alert you to when he has to go out?
