We used the air can training. Our Cali got a shot of air any time she approached the door whether we were inside or out. The air can went outside when we left. Even if we are inside and she starts to the door, the air can goes off and we say "no". She now knows what no means. Once we put on her harness and leash, she knows it's OK to head for the door. It took about a month but soon the training paid off. Occasionally we still have to do a reminder, but not often. Coming in from the outside requires just cracking open the door enough to be sure she isn't poised for a dash. Chuck
