my wife got me a Rottweiler about ten years ago. He's real mellow and laid-back. Her aunt is a dog groomer and cautioned us against getting a cable to tie him up but I did anyways. We were having our family reunion at our house and we were up on the deck and had him tied up in the yard. A toddler from the neighbors house wandered into our yard and Harley walked around him and when I looked down, the cable was wrapped loosely around the child's neck. If Harley had taken off running, the child would have been decapitated. I told Harley "stay" and he did and I walked down. Needless to say the cable got thrown out that day. I'm a retired cop and have been in more than my share of confrontations but that one still makes me pause when I recall it.
