True, but dogs can be bait distracted pretty easily MOST OF THE TIME. I say it like that because there was this one time when I thought the dog would take the bait and leave me alone, and he would have none of that. I got bit good as a result.
Dogs are also easy to defeat by sensory deprivation/irritation. Pepper spray sometimes works. So does a good ultrasonic transmitter. One of the quickest ways to disable a dog, and most any other organic deterrent, is a laser sweep across the retinas. Quiet, quick, easy, and repeatable.
