Dunskins will usually have the dappling that the buckskin usually presents, however duns can get dapples as well. I would still say Dun. Also if he had a injury that caused scaring on his dorsal his dorsal might turn white so it wouldnt show like a true dun. Stunning boy though hope to see what he grows up to be!
I think the dorsal will come back as his hair returns. And his coat becomes Healthy again. There is definitely a dorsal there it's just missing some hair but there is definitely a color difference and it's not like my bay colt who has counter shading. I think his coat is about to change some and as it returns it will go back to the chocolate shade it used to be. I'll take a picture of his back tomorrow. Posted via Mobile Device
