Wait wait wait. . .
That's a pinch collar.
I have weimaraners -- we use those same collars. They are far more humane than choke chains. They do *not* hurt. I put one on my arm and pulled -- I wanted to see. It's literally a pinch.
The "traditional" choke chains can cause major damage to the dog. These don't. My dogs hear the jingle and come running -- it means walk time! hehe
Choke chains do not cause major damage. Not when used properly, which is jerking very fast a *few times* when they are young being trained.
Meanwhile, aren't you not supposed to pull hard *at all* on a prong collar? Exactly cuz you don't need to; a little effort is very effective. Problem w/that is just like everything else. People want to pull hard on it because it's a natural (NOT because "that's what they do w/chokes" - so many people obviously eschew chokes as they do prongs), esp. in a desperate situation, and the prongs will stick into the dog when used hard - which WILL happen in tough situations. It's not a good every-day wear item.
(It's not just your post, but many making similar statements about chokes.)
Chokes are the only every-day wear collar that doesn't in itself hurt the dog, tells the dog he better stop it now when it has to be applied, doesn't require in the heat of a desperate moment that you try to restrain your strength while your adrenaline is up or you'll really hurt the dog, and in desperate moment on a lead, doesn't allow the dog to slip out and run free into the path of a 2-ton car (yes, this very scenario killed our GS Grand Victor a few years ago, only months after he had won the breed honors), and doesn't wholesale choke the dog's entire throat front when pulled hard (a`la plain old boring ID collars).
And if you want anecdotes, I'll just say my 2 GS have had chokes all their lives (1 died at 11), and have/had no such problems as are always cited by anti-chokers. Never mind that tons of Schutzhund people have their dogs wear chokers just as a matter of course - not just training times. Neither have various dogs I've known who habitually wear chokers had any "throat" or "eye-popping" issues. Such are probably merely anecdotal themselves, constituting a tiny % of those who wear them, and perhaps any actual technical damage is usually so minor as to be unimportant.
