My rat terrier is such an escape artist! We used to put him and my Mom's dog out front(where it is fenced) when we went out in the back(not fenced) when my son went to play. One day I was sitting next to my son's pool with him in it, and Kipper flipping out wanting in the back with us. All of a sudden, Kipper jumped, and started CLIMBING the 6 foot fence. I don't know how, but I always thought he was half rabbit or something because he can jump 4 feet in the air. And before we could move, he was over the fence, ran around the pool 3 times then he was down the street. Had to chase him. Everyone says wait, he will come back. Nope, not Kipper! He will keep going til he's tired, then he can't find his way back. I have a friend down the street when he notices Kipper runnning, will take out his pitbull, one bark from the pitbull, Kipper drops to the ground and doesn't move, so I can get Kipper and bring him home.
