So Corky is 1 1/2 yrs old and he has been house broken for awhile no issues really, but we just got back from camping where we would be gone and everytime we came back he was put on a leash and taken potty to a certain area. No problems. At home he is contained in an invisible fence with a shock collar. Before vacation he would go out do his doody and come in, no problem.. Since vacation he acts like he is afraid to go potty outside on his own and will only go if i put him on a leash and walk him. He has gone pee in the kitchen every day since our return and refuses to pee outside when I let him out. He just runs to another door and wants to come in. I have stood outside and repeatedly told him to go, and he will after a long time, begrudgingly piss! I am really frustrated with him. Also, since he was a puppy when he pisses he humps his butt while he goes, I call him a little pee pumper, but I am wondering if he has an issue peeing? Anyone had anything like this bizarre problem?
