i did this a few times.
the first time. "the horse is a kids horse and well broke" he was soo slow. that the other horses left him in the dust.. and that was only walking. nothing else. after they walked off and left this trudging guy, he decides to throw me in a briar patch...
the 2nd time i decided to be a bit smarter. they said "this horse is CRAZY and you can't get near her nor put tack on her or she will start running and bucking" well her ground manners were immpeccable. but her hair was so gnarled it took me 3 hours to get the knots out.. anyway i tossed a saddle pad on her.. and she stood perfect.. i tossed a saddle on her.. still perfect. she took the bit like a wonder. however she didn't know her directions that well. i decided to try more of a halter then a bridle so that it shows her the correct direction. she picked it up quickly and learned to used the bridle (this is us riding in a round pen) about my 3rd time on her we took her on the trail. and she was a PRO. walked right through water. lead, followed, trotted, stopped. and it was only her 3rd ride. we came to a clearing and a breeze came through the leaves and it scared her. she went crazy bronco and me i was still hanging on to my reins and my foot was caught in my stirrup. she drug me about 50 foot over gravel and rough rocks. i got back on her all bruised and bleeding, my shin sollen the size of a soft ball. and she continued on perfect the next 4 hours. not a single problem. she is now the best horse EVER.
3rd time.. a little less smart. the owner worked with him and he rode fine for the owner. he wanted to see how he did with me. the horse had clearly been abused. because the sound of a pop scared him (owner was riding a different horse popping him) the owner had only had this one for about 2 weeks (the one i was riding) he reared straight up (now unlike most people i am more comfortable with a rear then i am with a buck..) i tried to tell him the popping was scaring him. but he continued on.. as he kept popping his horse to go the one i am was on grew more nervous. eventually he went under a low tree and the sound of the leaves spooked me and we played ring around the tree while bucking and rearing. after being gauged in the stomache with my saddle horn i bailed..
moral of the stories? PLAY and mess and teach the horse and just be around them before getting on their backs! and even then.. always expect the unexpected..
