That would be the one in the Buck B story.
Yes, that woman was a hoarder and created that dangerous foal, but I also continue to disagree strongly, as to how Buck handled that situation
He was no different than CA needing to produce 'instant results.
For an aggressive stallion, the idea of roping a hind leg, the having a rider ride him, controlling the horse with that rope on a hind leg, pretty much sets such ahorse up to 'get that person, soon as opportunity arises, and exactly what that horse did, to the person who had ridden him
First thing, JMO, would have been to geld that horse, let him sit in a pasture for a month, and then start working with him. Maybe the same end result, with the horse being beyond rehabilitation, but I do see CA being really focused on, while trainers like buck, seem immune to any negative feed back.
Okay, going off topic, but just had to get this off my chest!
I raised a filly, weaned at one month, and she was one of the best horses I ever raised. She herself was very easy to train, and produced many great minded horses.
It is not the bottle feeding/hand raising, but rather the failure to introduce the same learning curve that foals learn from their dam and fellow herd mates, treating that foa llike a baby, having that foal consider itself human and at least equal to that human, if not through natural un corrected testing-superior
