@janbb You want barbaric? Here’s a story for you.
My grandfather broke horses when he was a young man. One day someone pointed out a horse to him that would always start bucking every time someone got on him. My grandfather said he could fix that.
So he found himself a 2X4 that was about 2 feet long and climbed into the saddle. When the horse took to bucking, Granddad clobbered the horse right between the ears with the 2X4, and the horse fell to the ground. When the horse stood back up again, Granddad was still in the saddle.
And the horse turned it’s head around and took a good LONG look at that 2X4!
And never bucked again. (Of course, they could have shot the horse…)
Like people, some animals learn. Some animals only learn the hard way. Without extreme measures, some animals will NEVER learn!
So tough love can work, and so many times it JUST TAKES ONCE!
When I was a kid, I once broke a dead branch over my dog’s back after she killed a chicken. And she never killed another chicken. (It was that or shoot the dog.)
As an adult, I made a chain and a collar for my dog that my dog could NOT get out of and hooked him up with a chain he could NOT break. It didn’t hurt him, but it cured him.
