How can I get Murray to ASK to go outside? We've had him for 2 weeks now, he was a rescue (3-year-old collie mix). He is housetrained, he knows he should potty outside but I've noticed he has never once asked to go out. We always initiate it, or our other dog Bear does. When we go out, Murray will go out and potty. But he has a few accidents, not just pee accidents either, and I know it was because we hadn't brought him outside in a while, or it was during the night. How do you get your dog to bark, or do something, so we know has to go??
