I had very limited contact with canines and handlers, but I will speak from one experience. We were an airmobile unit but attached for temporary duty to an ARVN (Army of the Republic of Viet Nam) division. Also attached were various support units. This included a canine attachment. I was walking past a tree where a canine handler had leashed his dog while he contacted his higher, highers, to find out what he should be doing. The dog snarled and barked at me and I was having none of this. I approached in a master/dog posture and told him to shut up and sit down, which he did. I offered my hand BELOW his muzzle for him to sniff, which he did. I sat down next to him showing no fear, (animals sense fear) and scratched his head and belly when he rolled over. I opened a can of C rations, "Beef slices, with gravy" ( more like hockey pucks in 40 weight oil) and shared it with him. (Poor dog). When I got up to leave he whined cause he was sad I was leaving. I didn't have to "string him up " and break a couple ribs with punches and kicks" The dog knew I was boss, and also knew I was his friend. Anyone who has to beat an animal to prove his superiority does not have the wires in their head connected.
