In this Nov. 26, 2012 photo, inmate John Barba looks at a calendar as he sits in his 6-by-9-foot cell that he shares with Dill, a veteran assistance dog in training, at Western Correctional Institution in Cresaptown, Md. Dill is one of three dogs assigned since September to inmates at the maximum-security prison for basic training as service dogs for disabled military veterans. The inmates, who are also veterans, are among the state's first prisoners to join a national trend of training service dogs in correctional institutions. Professional trainers say prison-raised dogs tend to graduate sooner and at higher rates than those raised traditionally in foster homes because puppies respond well to the consistency and rigid schedules of prison life.
