I have a question about my horse's fur! His coat looks healthy and shiny, but when you look at it, the fur goes in different directions making little patterns. He is a chestnut, but the patterns almost look like a paint, where you can see spots and swirls but it is all one color. It almost looks like big hives, but nothing is raised, and he seems to feel fine. Has anyone ever seen this before? He is a Percheron/TB cross. It is mostly on his barrel, and some on his neck.
