Now, if parti's all had the irish spotting gene, like some of the Biewers have, it would be possible to list the markings in a set standard. Irish Spotting gene has a predictable spotting pattern, characterized by white legs, white on belly, chest, chin, muzzle and tip of tail.

i find this interesting, would it be the same in a bridled dog. brindle seems like it comes in so many patterns.
