Puppies Behind bars
If the Philippines we have the dancing inmates, in one correction facility abroad they have a project called puppies behind bar. The project let inmates train dog to be of service to humanity. Dogs are trained as sniffing dog, companion dog for the blind, and as companion dog for war veteran.
In this system, they are bringing back the humanity to the prisoners. They are letting the prisoner feel that they are still a important part of the society.
