I mean.I mean. That's okay? You don't have to be impressed. My point was - and still is - that you can work a bitesport dog without shock collars - or any correction - and do it quite successfully. Whether or not you're personally impressed, she's competitive at Nationals with quite high scores on her dogs. Just pointing out that e collars are a choice, not a necessity, in 99% of training. Including venues where they're still in frequent use by high performing dogs and trainers.
The judges are impressed.
And the judges are who's opinions matter, so.
