Puppies Behind Bars (PBB) trains prison inmates to raise service dogs for wounded war veterans and explosive detection canines for law enforcement. Puppies enter prison at the age of eight weeks and live with their inmate puppy-raisers for approximately 24 months. As the puppies mature into well-loved, well-behaved dogs, their raisers learn what it means to contribute to society rather than take from it. PBB programs bring the love and healing of dogs to hundreds of individuals every year. The dogs bring hope and pride to their raisers, and independence and security to those they serve.
