That is a nice looking hoss, they are my favorite breed of gaited horse, maybe it is the body looks like a stockhorse to me. Is there a need for four or how ever many assocation there are for the same horse. KMSHA, RMHA, KMSHA, and there are several other I think.
There is the RMHA,KMSHA,UMHA,AGHA,MPHA,& I think that's about it!lol. She can be registered eveerything except MPHA,but I just havent gotten around to doing any of them except RMHA since it the only important one.
But no, not many horse are registed MPHA (its kind of going under), but RMHA is an actual breed registration. The rest are just open to naturally gaited breeds.Most people just register them that to be able to show in the Association shows.
I don't know much about that breed and the shots can't be used for a confo critique but I will agree with Vidaloco. I looked up some photos online of some of them and it seems that generally speaking she seems to fit into the typical breed characteristics (color included).
