Zander has that on his butt, actually! Just looks like I left the rake marks on him. Lol. And that's definitely true. I know it's common in Alaskans. I'm just not sure which breeder brought it into Sibes, though. They are out there and spreading in performance lines definitely, but not able to be shown and somehow, some one is breeding them into the conformation lines. I just can't trace it back since there are so many people in that group now. Shady Sibe people.
