I have a purebred mustang stallion. He is an oily soot black. His name is SootBolt. It's time to start his saddle breaking/tacking up training and he is 16.9 hh and he is very strong. the strongest horse i've ever had. b4 i broke my leg and arm i got onto his back and i was off in a matter off seconds. NOBODY can get on his back! and i've always been the one to saddle break our horses since i was 8. so i'm very very very good at it and i've only been thrown off a horse 4 times while saddlebreaking (counting this time) he is incredible fast and tall i mounted up 4 days ago and wasnt thrown i just had the saddle on him and was trying to have him let me mount up and he bolted and went straight through a fence! we finally calmed him down enough and took the saddle off we've been working with him on this since he was 1 1/2 years old and he's now 2 years old. it's very dangerous to get on him...my cousin (Jaziyon) was thrown off and broke her femur, collar bone, radius, tibia, fibula, ankle shoulder, and right cheekbone! as you can see i have no CLUE what to do and i've been saddle breaking horses for 9 years!
