What pets do you have? I have a lab mix, and I also have a doxon. I absolutely love both of them. They are very fun to be around, but the lab mix isn't really trained to handle the outdoors. If you were to leave the door open, she'll run away and she'll think it's a game when you chase her. The doxon, on the other hand, handles the outdoors very well, and doesn't even need to be on a leash.
