I had a ornery spoiled quarter horse mare That I brought home to train. She was a nasty one. She tried to kick me and bite me because the previous owner spoiled her. She had no fear of humans and was dangerous! I set about to change that. I lounged her and watched her carefully. Working with her daily. I was putting her back into her paddock and I turned my back to shut the gate, She bit me on the back. Out of instinct and reaction I turned and readily roundhoused my fist connecting to her lower face between her nose and the bone just above this soft place. She went to her knees and never but again
The moral of this true story; don't spoil!!!
