So again, today I'm delivering to a house with a loose dog (small one, but aggressive) waiting for me to exit the truck. Owner comes out with a baby in her arms and commands the dog to sit. It obeys--until I step down out of the truck with a heavy package in my arms. Then it ignores her and is trying to bite my legs as I'm stumbling around trying to get up her steps. Finally? She gives up using ME as her training dummy and grabs the dog's collar , restraining it properly. I'm wondering, if I weren't the UPS guy, but your aged father, or your visiting sister, or your boss, would you use me to train your dog? Or would you make sure its 100 percent restrained out of respect and safety? I think I know the answer to that.
