OMG what a load of crap. Have you actually used one? No. I have years of experience with them and this is not possible because they do NOT stab into the neck at all, as the collar tightens they close together. I'm saying it's nicer on a dogs neck because a boxer hitting the end of the lead IS going to injure it's spine or neck very quickly. Prong collars are nicer then correction chains on strong dogs because they can only tighten so far like a martingale and do not put the same pressure on the neck as the chain. I've seen dogs do security work pulling into a prong, if it caused that much damage and pain that would not be possible. Stop reading hysterical websites made by people who have no idea.But there is also a slight risk that your dog will continue pulling to get away from the pain and end up unconscious due to a pierced windpipe. I don't care if you say that the risk is small.
As for a dog that panics and tries to run, NOTHING will happen. Nothing more then a martingale will do. A prong collar is not rocket science at all, that's just another fallacy about the equipment that it is 'last resort' only or for the minority. Put prong on dogs neck so it's snug but not tight higher up on the neck but not right up under the chin, attach leash, hold leash properly and only small pops required, then redirect the dogs attention back to you and reward for good behavior.
