I watched prison dogs and Police dogs being trained, before I supplied them with suitable sniffer dogs. I would not supply to the Army, but having a friend that has one retired and two active working Police dogs, and watching them from the start, I have no qualms at all about the way they were trained.

hi i work part-time with police dogs and i can say that in my area the dogs are trained with positive reinforcements!! we do get some handlers who are not natural dog people but they soon learn how to get the best out of the dogs, all of our dog handlers really love their dogs and keep them when they retire
