Experts can be wrong. The cost of the collar would have been nothing, if it alleviated your problems.
Plus they might not have been aware Sportdog made the 400s, which is a *lot* stronger than the average training collar. No way your dog would have ignored this pain. He would have panicked, tried to figure out where it was coming from, looked to you, and that would have been the moment you needed to seize control.
Again, I haven’t seen your dog, but I had two, from a “breed” which was reputed to be untrainable (another I had of the same “breed” was the best trained dog I ever had - so much for the experts), they were out of control, and wholly ignoring me, the prong collars, my commands, and everything else.
Within minutes of being shocked, I was in control and they were going down with no questions and staying there. And within minutes of being together, they weren’t fighting.
Those dogs knew no pain, but they were easily controlled with the collar. Just file it away that it’s possible - it could prove useful someday.
“No way your dog would have ignored this pain.”
LOL. He’s been near unconsciousness a couple times when he wanted to kill something. What is the setting just shy of “electric chair” with that? Can you recommend a way to get rid of the burning hair smell? Peddle your collar to someone else. I’m familiar them. They are not suited for my dog’s situation.
