Dog fans seem to have that oddly purblind (dog-like?) inability to see why non-fans don't have an appreciation of, or even sympathy for, the entire inventory of dog antics. It's a simple one: keep your dog on leash or keep it fenced in so it can't get out of your yard un-tethered. End of story. If you hit a dog roaming or chasing on the street, it's the owner's fault, and go after him/her for compensation.
