Well Jump, I agree with you. Especially now days, when many of these horse registries are simply registries; not actual breeds. You run into this often in the gaited world. A Spotted Saddle Horse is any gaited horse of color. A Kentucky Mountain Horse (like mine) is usually a Walker, although some come from Trotters. My horse actually has 3 registries. I was told he was a Walker, but he fox trots and racks, and is not registered as a Walker, but as a Mountain Horse. (I have been told that Rocky Mountain Horses and Kentucky Mountain Horses are the same except for color... at least that was 1 opinion!) I was fortunate, did extensive tracking and got lucky; found the original breeder, who was "up in years" and no longer in the business.
It didn't matter to me his breed. Like you, I love my horse no matter what. But my findings help me understand what I could and could not expect from him in the way of gaits. Now that I know what I am working with, we are doing better on and off the trail! Good luck.
"Do you give the horse its strength, or clothe its neck with a flowing mane?" (Job 39:19)
