YumYum - I've got the same problem with my Panda. She bolts on me to get to the outside and I can't catch her. She comes home when she's ready. It hasn't been too bad this winter since it's been so cold here - she prefers the inside, but now that the weather's warming up I think I'm going to have this problem again. I just try and be cautious when opening the door to come in and go out. I say a firm NO and it will usually back her up, but nonetheless sometimes she's too quick for me
