No but they have old ones. And actually I'm not going to, because, no offense, but I've been told I'm wrong on like everything I've said about colour on this site... Also even on facts of my own horse's breed
Just like I said... Old. And not to say they don't occur in other horses, but there are ones that occur way more often in mustangs than domestic horses. Like some dun factor markings, like the Nokota (not necessarily a mustang), one of their most common colours is blue roan... rare in most breeds. And also dorsal stripe under the belly too.
And huh, just a thought, up where I am I know a lot more about horses than most people do, though by comparison in age I am young
Well I don't mean nokotas in particular. I mean indian bred horses because a lot trace back to spanish horses. Especially ones like Kigers because they were isolated and had no interference with any other breeds for who knows how many years
Lobo dun does not exist. It is not a colour. It isn't real. Who ever told you that it was, didn't know what they were talking about.
Nokota mustangs are not the most isolated breed in the world. That honor goes to Icelandics. And guess what. They display colour the same as every other horse. They have been isolated and breeding only to other Icelandics for just over a thousand years.
