The kids are paired up as trainers. Primary, Support and Sitter, so 3 youth for each dog, usually selected from different "hoods" "gangs" and "race" to promote teamwork and a commonality. . They're interviewed for participation in the program. They must have good behavior and maintain "points" to participate. All the kids on each unit are allowed to interact with the dogs unless they are inappropriate, but the trainers are in charge of caring for, training and managing the dogs. i have 1 dog on each of 3 units this go-round. 2 YOP (youthful offender program) units, a transitional unit,15 or so kids. 9 month program where the youth learn life skills and a trade prior to monitored release. ! female unit, 1 male, open dorm setting, very strict. Dogs roam about with supervision, sleep in a crate or on a mat with the primary. 3rd unit is heartbreaking. Boys unit. Highly restricted. no more than 10. These boys have committed violent crimes. They sleep in cells and have a day room. They never leave the unit. They have a large exercise area. Their classroom is in the unit. Those are the kids I help the most. They've been failed. If they have parents, one or both are in prison. Generations of gang affiliation. If they don't commit the crime, they get killed. The juvey gets a lesser charge., Nuff from me. Hope I explained without going overboard. If I help just one to learn a different way.
