I'd call it piebald because I'm English and have never got all these fancy terms for coloured. I don't think it changes from breed to breed but Americans have names for all the patterns which are filtering into other countries so where as a piebald would be a piebald they're now a tobiano black and white. I think that's how its working.
Sorry guys!! I was very mistaken...my bad :) BUT I can asure you that the horse is real
Ok but I think that you should post another pic of it with crap on its flanks and its head down, with floppy ears and it's eyes closed or else it is forever going to be in my head as Barbie's horse LOL!
I don't think she's a Palomino....she's red. I heard she's a strawberry roan? I think she probably looks Palomino because she's sun faded. But thanks I didn't know she was an overo. Not really familiar with paint patterns yet. : /
