Ok experts, here's another question for you. It feels like Bear and I are starting to get the hang of this housetraing. Now I need to know how I will know it's time to try him outside of his crate. Also, how do I teach him to let me know when he needs to go out or is that something that comes natural? He does usually come to the door outside when he's finished doing his business to let me know he's ready to come in.
