Cowboy dad, The collars have been out for a few years and are gaining popularity. They are being used mostly for cribbing and other such vices. My friend used his dogs collar, he raised and trained field trail dogs. He should have marketed it back then (10 years ago). I no how RPETRACEK feels The cattle prod has crossed my mind before (I knew you were joking). It just gets frustrating when they do things that can hurt themselves or others.
