I once worked with a guy whose method of getting his horse ready for the day’s work was to go and cut a branch, about 2.5 to 3 feet long, and around 1.5 inch in diameter, wedge himself into his saddle and proceed to beat the horse until it started to buck, once it was bucking he would continue to beat it till it stopped bucking. Most of his horses were afraid to get on and off the truck, so to get them off his methods were similar. To get them off- open the gate to the truck, climb on top of it and beat them until it was more frightening for the horse to stay inside than get off. To get them on- try to drag them into the truck, when they got their heads in and wouldn’t go further he would tie the reins/lead rope to the inside of the truck, climb out of the truck and get behind the horse with a piece of rope leather belt, and flog the horse till it was more afraid of staying outside of the truck than jumping on. He was worse to his dogs. If they barked while tied in the back of the ute he would beat them with a shovel or grab them by the tail and back legs and jerk their whole body back hard as if he was trying to snap their necks on their collar, which was chained to the head board of the ute. He was a real piece of S!@#.
The person who taught me to ride said the worst he ever saw was at two different places he went to look at buying a horse. At the first place, he arrived and saw a horse tied in a round yard with a piece of rope the likes of which, in his words, was so thick and heavy “it could be used to tie a battle ship to the docks”. He said the rope was so heavy the horse wasn’t tied up so much as just weighed down by the sheer size of the rope. He went from there, horseless, to the next place where as he drove in he met the owner/horse breeder driving down the road in his 4WD dragging a horse along tied to the back of it. He asked the guy what he was doing; apparently, it was how he taught all his horses to lead. My friend offered to teach him to teach his horses to lead without needing to drag them down the road. The horse breeder got offended and assured my friend he know what he was doing and didn’t need no help from the likes of him.
