Workers at an animal shelter in the UK became perplexed when they found many dogs running loose out of their cages each morning. After ruling out lazy employees and practical jokes, they set up surveillance cameras and discovered that Red the greyhound had figured out how to pick the lock to his cage. Then, AFTER helping himself to treats in the kitchen, he would also bust out some of the other dogs (those he was known to get along with the best) to play.
