I have a half arab half/ half indian paint, but my understanding is that's very similar to calling her a half arab/half QH? Is there a distinct difference between a paint and a QH aside from the coloring? I registered her with the AHA as a half Arab, and was going to double register her with the APHA but I don't really see the point other than for breeding or selling appeal - I plan on doing neither. I love the cross, because you can totally tell when she is being an arab, or when she is being a paint, lol.
Your horse cannot be registered with APHA because Arabs aren't allowed.
Someone correct me if I"m wrong, as I dont' have stock breeds ;)
