Puppies Behind Bars

Prisoner / Puppy Portrait
Tyrone sits with Happy, a 4-month-old. Tyrone has served five of 8½ years for threatening someone at gunpoint. "I've learned not to let these walls make me a prisoner of my own emotions," he says. "The program has taught me to be patient, honest with myself, and how to work without ego. My last dog, Yankee, went to a war veteran somewhere in Colorado. Just knowing that I helped to change someone's life makes me feel as if I have a purpose and a destiny. These dogs have a way of touching a person's spirit."
