This chihuahua was caged all his life. When he got free he did this!

Dogs have been friends with humans for nearly ten thousand years. The two species have grown close together and have both benefitted from working together. But not all humans are nice. The people who owned this puppy mill have committed an act of indescribable cruelty.

Fortunately for the dogs, there are groups out there like The Humane Society. These groups strive to rescue dogs from situations like this and to rehabilitate the dogs they rescue so they can find loving homes.

This video focuses on a dog named Billy. Billy was rescued from a puppy mill. This little Chihuahua was just skin and bone when he was rescued. Even though Billy had been mistreated his whole life, he was not depressed or aggressive.
