His feet are a bit big for traditional cob and his back is a bit long for a shire, I would say Clydesdale x cob, maybe quarter clydie? I wouldn't think there was lots in there as he's lost the paint effect in his legs and his back is still quite long for a clyde
I do love these guess the breed. Do you know his breeding or is he a heinz horse?
I think cob x highland maybe as he has a dorsal stripe that you can't quite see in the pic - tehe but then I've met the gorgeous boy himself! Tho is head is huuuge (full of brains obv) so I'm not sure where that comes from exactly!
