I know there is appy in there- from the mottled skin, striped hooves and sclera, but other than that? Your guess is as good as mine. My farrier and vet both feel she is part clydie, I can see that. Her legs and feet are thicker than my big quarter horse.
I do feel she is a bay also- but the dorsal stripe threw us for a loop- and with all the white coming, both spotting and now roaning on her butt, she is going to be odd looking for sure.
