I adopted two adult Germany Shepherd dogs and they are both slightly over a year old. The two girls were rescues and always stayed in a larger kennel so they crapped, and peed, ate, and slept in their kennel. I feed them and they are outside for several hours. They then come in and first thing they do is pee and crap. This is going on months. Anyone have advice on housebreaking an adult dog who has been a rescue since they were puppies?
