I raise guide dog puppies for Guide Dogs for the Blind, so I pay attention to any articles about raising service dogs.  This New York Times’s article, Who Let These Dogs Out? talks about a program that has prisoners raising and training puppies and then socializing them with urbanites on weekends.  The urbanites are people who can’t have a dog due to too little space or too little time.  Both the prisoners and the urbanites benefit from a relationship with a puppy.
