I purchased Patches as a grade gelding, but his previous owner & trainer thought he was probably an arab/paint cross. He has an extremely thick mane and is only 14HH, so my farrier thinks he has some sort of pony in him (she thought maybe hackney?).
Also, I know there are DNA tests for dogs that can help determine breed. Is there anything like that for horses?
I also don't see really any arab in him, especially looking at the head. I'm thinking mostly paint, maybe with some breed of pony way back which contributed to his size. Whatever he is, though, he is pretty adorable =)
