Amazing video: Dog Escapes Shelter Pen Nightly to See His Friends!

This dog observed and learned how to unlock all pens in the shelter and would then escape nightly and let his "best friends" out of their pens. Each morning he would be found back in his pen with all of his buddies hanging out with him. The staff was so perplexed, they had to install security camers to figure out what was happening; they finally did and the footage is amazing!
