Mliponga: I'm assuming you don't realize that POA is the pony-version of an Appaloosa? POAs are given temporary registration until they are 4, at which point they are measured to make sure they are within the "pony" range, still. If they are not, I think (not sure here) that they might be elligible as an Appy (prob not, though - think bloodlines play large role, Appy not just color breed?). I would say some sort of other pony: he doesn't have a POA face... it is more pony-ish. I would think shetland, with how small you say he is. Super-cute, though! He's got the round pony build, instead of the "little horse" build of the POA, which is what makes me think Shetland/POA or something along those lines.
