Cindy.... Here is the fine line that you will find between horsemen. Those prone to severe treatment of their animals claim they work because they claim to have solved the most horrible behavior using these extreme tactics. What they don't realize is that the horrible behavior often didn't happen without a reason.
Horses can be made to comply out of fear and pain. You can beat them into submission. But fear also brings with it many other instincts of self-preservation that are dangerous behaviors. The rougher the cowboy, it seems the more extreme behaviors they are forced to confront. I have never had a horse that would bite me when I got on, but then I have never had a horse that through pain or rough treatment ~resented~ my riding that much.
In other words, you will get better work out of a horse that trusts in your leadership than you will a horse that only fears you. What is trustworthy leadership? You know this... Firm, in charge, clear and consistant rules, kindness in reward and fairness in punishment.
I watch and I see different styles. I had to find mind. My horse has shown me his teeth a couple of times and got popped. I read all kinds of stuff to do if they bite you but I've decided the first time he does I'm just going to bite him back:') (how is that for staying on topic on a horse eating thread?)
