if you look at the hairs on his back on the half nearer to the rump you will see some pearly guard hairs. they are pure shiney pearl white. under them is a mocha coffee color. in a downy soft fur. the guard hairs are thick and silky. I've never seen a distinction of hairs like this with two distinct colors and seriously different textures. are there any breeds known for this or is this a random type thing. lol. he's always had them but it's a lot easier to photograph as he gets older and the under color gets darker.
