Chokes / prongs are all part of a "kit"of tools that people use. Just like halti's, harnesses, martingales, e-collars, etc. Some are more intense than others ... designed for dogs with specific issues that you are trying to address.
Personally, I never used any treats to train my dog in ANYTHING ... nor did I use a prong or choke. I used a martingale to train my dog, and yes, she got a quick correction with the leash. I trained her YOUNG so I don't have to deal with 99% of the issues that I see crop up here on the forum (for that I am eternally grateful).
Do I think that using treats as a reward for good behaviour is the way to train a dog? No, but I'm not on here bashing people about how they train their dogs ... nor should other people be getting upset at those that use a different method AS LONG AS THE DOG IS NOT GETTING HURT.
OP - have you watched how some of these K9s are trained? watch some youtube videos that people have posted in here on SCH ... these dogs are not being abused by any stretch of the imagination - they are being corrected firmly, not with abuse / maliciousness ... and they are not getting treats popped into their mouths every time they do something right.
