This. I have a head halter for Abrams purely for a public relations reason: when he's being a reactive idiot upon first leaving the car, he's less "scary" on a head halter than on a prong to people who are in thr area. He HATES it. Not much shuts him down, but he despises that head halter. And, honestly, it makes sense for him. He's less sensitive around his neck (thick, loose skin, I used to use his scruff as a hand hold when I needed him to move and he wouldn't comply as he doesn't wear a collar in the house/yard, etc.) but his muzzle is very sensitive. I can get him to back away from me purely by laying a finger at the bridge of his muzzle and applying light pressure. Holding his muzzle shut or grabbing around his muzzle to hold his head still is *extremely* aversive to him to the point he will flail and panic if it goes on for more than a few seconds, especially if he is worked up about something. (He could care less about being held under the chin, or by the head itself.)
A head halter, for him, is 10x more aversive than a prong. And I'm sure he is not the only dog where that is the case.
This is a dog, who if he wants to, could probably drag me. He has good leash manners, but I know there will be a time where something causes him to pull because I cannot control the environment. And when he does, I need to be able to effectively stop that from happening before he or I (or what he's reacting to) gets hurt. A prong is my safety net, and he's perfectly happy to wear it. A head halter? Not so much.
I'm not saying thay head halters are horrible, evil things. They aren't. But neither are prongs. I got into an argument with my friend last night (very briefly before we both said "this is dumb, let's not fight") because she was adamant that a prong was cruel and abusive because the prongs "dig in to their neck" and "cause unbelieveable pain". Um. No. Not at all. We ended our discussion with her saying, "Well, Abrams is just a masochist." That is probably true.
