The part about talking to him even though he doesn't understand is a good one! I was a drug dog handler in the USAF, these were highly trained dogs that were trained not only to detect narcotics but to track, scout and controlled attacks. I had a dog in Turkey, he was a mean sob, when I first was assigned to him, before I entered his kennel, I spent over three hours outside of it calmly reading a book to him out loud. I was finally able to safely enter his kennel and leash him up and start working with him.
