Paso Fino, Peruvian Paso, or Peruvian Horse (NOT The same as Peruvian Paso) would be what I recomend. I have owned three over the years....but th eone I have th emost memorable experience with was my boy Rico.
Mom had back surgery last year and at the time she had a mare that had bad gaits.....and none of the horses I had were much better. She wasn't about to stop riding, so as an alternative I bought a little Peruvian Horse gelding from my trainer for cheap. He was only $500, a little bit younger, but he was bombproof, trustworthy, and the smoothest ride I have ever felt.
First thing yu need to know when getting one of those three breeds is that they do pine or their previous owners. For the first week or so they will most likely not want to be around you, nor will they be easy to love. They will do what you ask but their heart won't much be in it until later. When I bought Rico, I thought about trading him for something more friendly but couldn't find anything in the price range. So I waited, and about two weeks after we brought him home he started nickering to me, getting excited to see me, and we had a real bond even though Mom was his primary rider.
The next thing you need to know is that they will take some getting used to. After riding my reiners and cowhorses I really was kind of freaked out by this horse. He walked, but he walked fast.
They "Swim", if you will. They will be something that will lead the pack on a trail ride. The first timw I had Rico out we left everyone in the dust. We were stopping and waiting, doing serpentines, and all sorts of things.
And they will trust you, even if you are leading them into something stupid. I was riding on a trail, and there was a bee's nest on the gorund that I didn't see. Rico stopped, snorted, and looked at it but I didn't see it so I made him go forward. His expression was "Okay Mom....If you say so..." and we stepped right on it. I felt so bad afterward. I spent so much time putting medicine on his stings and giving him lots of love.
These horses are very
good at communicating with you. Another story I have about Rico....I bought him a Bosal (He never wore a bit) and it felt like soft, comfy leather. I put it on him and walked away from everyone. About a quarter way into the trail he started stopping and refusing my commands. I was pissed off at him, since there was nothing to be scared about. I gav ehim a good smack on the butt and he just totally shut down. He turned around with the most pitiful look and touched my stirrup with his nose.....and right where the Bosal rubbed the fur had been scraped off and there were little spots of blood. Another stupid moment for me....He had been trying to tell me, and I hadn't listened. I didn't even think about it, since that Bosal had been so soft to my touch. I made sure nothing like that happened again, but certainly that didn't make me feel better....Poor guy. In summary -
Any of these breeds will pine for about a week or two after you bring them home. They will follow you into any situation and will love you even if you do something stupid like I did. It will also take you quite some ime to get used to their gaits. You will never find a better companion than the Paso Fino, Peruvian Paso, or Peruvian Horse (Once again, NOT the same as a Peruvian Paso.)
Haha, sorry for the novel.
