Most departments buy "green" dogs from established brokers. Brokers are many times retired K9 officers who establish a business selling dogs. They go to Europe and buy quantites of dogs from brokers or contacts there. Most K9s are unpapered. It is very common that the township and police deparments own the dogs and do not want them used in breeding, thus the papers are not transferred or even provided. I know a few K9 guys who just breed anyway, with no papers, no health clearances...they like the dog, they breed it and sell puppies for a few hundred bucks each to locals who think it is cool that their puppy's daddy is a police dog.
Civilians are rarely let into this world. Even establish breeders. I had a few friends who trained who became cops. I know a few, and a few of my dogs have found their way into the hands of LE and onto a force.
Carmen knows much more about this world.
