That is a very good pointIt's not really a "last resort", I agree. But it IS more sharp of a reminder than the martingale. With my horse training background, I know that it's important to teach the animal to respond to the gentlest of commands. While using something "harsher" or just more abrupt in general can be helpful, the animal will no longer respond as well to those lighter commands. Obviously horses and dogs aren't the same, lol, but there is crossover.
