I think that is a win-win situation for all. The dogs obviously cannot be pets. They have great care, are not chained up, have plenty of exercise & get interaction w/the trainers/handlers and are doing what is in their nature to do...protect & guard. It sure beats euthanizing a dog, when that dog can still have a safe home. I can also see where having those dogs would cost alot less than installing new systems, new equipment & training.
Not a new idea though. The used the same idea on the eastern german side before the fence came down. I also heard about a swedish prison utilizing guard geese. You can silence 5 dogs with meat ,but you cant shut up 100 geese.
