I have seen a couple of crazy horses though. Don't know if they were born or made that way but loco.
That is actually a pretty good book that we got for ecurbh to read. My 'cowboy' friend Bob recommended it. It is all about studying and correcting behaviors, and he liked it because despite the cutesy name, it speaks to adults. So many of the "learn to ride" books are geared toward kids that it is hard to find books that don't overly talk down to adult learners.
I've seen a bunch of crazy horses, and it doesn't matter what made them that way.
If you're working from a remuda of quarter horses, you take 'em as you get 'em.
Most horses who whip their head around as you climb in the saddle aren't intent on biting you. They might nip at your pants leg to let you know they're not interested in going for a ride right now.
There are some who will chomp down on that leg like they want to eat it!
Sometimes a good lick between the eyes with a lead headed quirt will stop that, but sometimes more drastic measures are required.
At the Boy's Ranch we had a palomino who loved to rare up like Trigger.
The chest strap did no good at all.
One day he went over backward and fell on the boy, breaking his back.
We put that horse down with a .30 caliber through the head.
The proud cut gelding tore the top of a boy's head off when he purposely ran under a mesquite limb.
We found him in the pasture, and got him to the hospital.
He's still wearing a steel plate in his head today if he's alive.
My son's eye was torn out when he was riding a stallion he thought he could handle.
They put the eye back in, but the scar down his face is still there.
There are some crazy horses, and anyone who thinks there's not are as crazy as the horses.
There! That's my two cents!
Flame away! I'm gone!
