Yes. It seems crate training is super important as safety to the dog. As to B escaping, I am not too worried as at my house there is a inner court yard that has another door leading up to my front door. Usually when people ring the door bell, they ring the outside bell. I though have to go through 2 doors, which is great especially if the dog escapes from one door, he is stopped at the other 😉 That portion I am pretty confident.
