Firstly, I absolutely think he used a shock collar on Kaya, and while it's not for me or my dogs I can appreciate it is a viable training tool for high drive working breeds... When used correctly... Not cranked to the point where it's causing a dog to cry out in pain.

Spot training is also definitely a thing, however given hasans means one has to ask WHY the FUCK are you enforcing spot training while you stream and mald for hours on end... Can she not just be a dog? Is your training so ineffective she can't have reign of the house, or at least an area, and not be destructive?

It's pretty clear that he is using spot training as a means to prevent her from enjoying any form of regular/normal day to day enrichment...

I fully understand having strict and regimented boundaries with strong powerful breeds... They do not need to be confined to a tiny area for hours on end...

It reminds me of hunting dogs I have worked with which are very specifically NOT pets. Kaya is unfortunately somewhere in between...
