One would think that with all the training police and first responders are required to take and pass, they’d have a rudimentary understanding of the clear signs a dog will display-aggression, fear, apprehension, playfulness, contentment, etc. Dogs will tell us their state of mind by their tail, posture, ears, eyes, maul, etc. Testosterone laden LEOs who display innappropriate aggression may well light the fire that will force a pack animal to defend his or her pack and territory. Perhaps if cops carried more dog bisquits than hollowpoints, fewer senseless canine executions would occur.
