Well, I own a beautiful Quarter Horse gelding called Mr. Lopez. He's about thirteen. He's has a lovely walk and a great canter but he just /can't/ trot. I mean, It's like he can't decide to trot or not. It's all over the place, fast and then slow and its extremely bumby. You can't sit to it and rising to its even harder. It's like he never learnt how to trot. My mum's horsey friend even jumped on him and couldn't sit to it. I don't know what to do about it.
So if anyone can give me some advice? It'd be greatly appreciated~!
