Thank you for the information, but I did also look at shock collars and did research. From my research, from experts, it was said a dog like mine needed a dominant dog collar and not a shock collar. His drive and focus are too strong and pain would not, will not deter him. I agreed with that assessment after working with my dog extensively.
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.
Kidding!!!! ;)
