I don't have a problem with appropriate use a shock collar. In the right hands and right circumstances they can be literally life savers (explain that to the yogurt nitters!). However hes obviously had the collar for a while on this dog, If it keeps escaping, and or ignoring it then its not working. Which should have been a signal to try and find other methods of containing or training the dog. For 2 grand he could have built a decent fence, or that most complex of devices, a bloody chain!
