well that was a sharp response to someone looking for help. I guess we all can't be starting to learn about our horses. I guess you were just blessed knowing everything without haveing to LEARN...
Would you prefer to be dead, or crippled for life? This isn't a game. These are large animals with free will, capable of doing intentional or unintentional great damage to themselves and others.
I started the right way...with a well-respected and successful mentor. Did a two year apprenticeship with them and passed an elaborate test to become a licensed trainer. I kept my mouth shut, watched, then researched and studied at every opportunity. I continue to watch, research and study, though admittedly the mouth opens far more often now because I've got something to say based on a lot of experience and knowledge.
You asked a question and I gave you the best possible answer from my 25yrs of experience. If you want to learn to swim, you don't jump into the ocean, you start in a kiddie pool with water wings and work your way up.
If you aren't in a position to learn under better circumstances, then you're best to wait until you are. Since you're unlikely to listen to that, I've told you how to stay alive and be as safe as this situation allows for.
