I have four dogs but one of them always has accidents in the house. The dog is a labradoodle. I have caught him one or two times. We have a doggy door and the other dogs don't have problems. I don't always reprimand him when I find urine on the floor because I didn't see him do it. He is now two years old. There is no medical problem and he is a rescue dog like all the others and we've had him now for over a year and a half.
