My Pit/Walker Coonhound mix was an escape artist -- she climbed fences of any height, opened gates, and also opened doors and windows. She even went so far as to jump out of a second-story window on the 4th of July while we were gone for the fireworks. Luckily she only tore off a toenail doing it. She was picked up by local law enforcement, who took her to the pound and put her in a kennel. He turned around to radio in my details so someone could contact me about her, and she was already sitting perfectly by his side begging for attention.
