rain rot at one time and the spots were the regrowth hair
I'm super curious about this. My barn owner had a thoroughbred stallion that had a couple good sized gold spots on him, he was a nice red chesnut. I didn't know if it was scarring or what, but he had one colt out of a bay mare. The colt is also chesnut, with random gold spots and a dark spot on his forehead above his star
We joke he was trying to be an appaloosa, but I have no idea what its from.
