“Puppies Behind Bars” gives cute lil pups to hardened prison inmates, who train them to eventually be guide dogs and police bomb sniffers. The puppies teach the convicts as much, if not more. Being responsible 24/7 for a dog can turn the most hardened criminal’s life around. “This is my way of doing something to reparate,” says one murderer. Some say it’s their first taste of unconditional love. “The strongest guy in here’s going to get that lump in his throat,” says an inmate. The dogs get weekend furloughs to NYC so they can get used to city streets. No convict who trained a puppy has gone back to prison after being paroled.
