I think some dogs are just never to be trusted. With my Maddie, when we are going out a door for a walk or into the backyard to play, she will ALWAYS sit and stay until she is released to go. But... ALL bets are off if no one is around to give the commands. I had some work done on my house and twice workmen left a door open that we never go out, but she saw it open and off to the races!!! My only saving grace is that if I holler "wanna go for a ride" she turns tail and races back to me for a car ride. That girl loves a good car ride!
