I am a newbie who joined today. I have my first horse who is a 14 yr old saddlebred. I am 5'3. He is 17hh. So, he has quite an advantage. We started just walking and a little trotting on day 1. I think he had too much to eat because about an hour into riding he layed down and rolled. I had to jump quickly not to get smashed. Day 2, my saddle broke and off I went. The saddle went under his belly, and I landed on my back. Later after the saddle was fixed we rode for a couple hours and I attempted a gallop since the horse we were riding with (that he follows) was speeding ride by at 18 years of age. All of the sudden up comes the front legs, as i'm coming off, up came the rear where my back hit before bouncing onto the ground. Sam (my horse) didn't run he looked and walked slowly to me like, "what did I just do?" I cried because I was heartbroken. I couldnt understand why a horse of pure muscle wouldn't want to just take off. I did get right back on and he attempted to buck a couple of times at a trot or walk and I gained control. But I went home just in tears. I called my friend (previous owner) and she said that Sam had never done that before. Never rolled, never bucked..none of what I was experiencing. So yesterday...the previous owners came over and used their saddle...girth..and taught me a few things that Sam was accustomed to. I could not belive the difference. He galloped. He neck reined (if we crisscrossed the reins) he let me ride him. It was wonderful. Hopefully, this will continue. We did hit a tree while galloping, but that was nothing compared to the rush of the glided gallop that I love so much.
