How can i stop my dog from urinating in the house after we took him out but refuses to go
Sounds harsh, but leave him outside. It you got to, leave him on a chain. Let him stay outside. If he pees on the floor, rub his nose in it, spank him mildly, and put him out in the yard.
When you take him outside to pee, ensure that you leave him there for a few minutes so that he realizes that you are being firm with him. Eventually he will learn to pee outside and immediately he does, reward him with something that he likes.
