Thunder's tail can get REALLY bad if I let it go, so to initially get it manageable, I scrubbed it up with shampoo during his bath, rinsed it, making sure it was all the way through to the stubb part lol, and then just put a bunch of cowboy magic in and rubbed it in all the way through so it's not just on the outside, then let it sit for a bit. Then I took my brush that is similar to the pic at the top, but not so many bristles and its oster and brushed from the bottom to the top stopping when I hit a tangle. I do try and help the tangle through with my fingers as well as my brush. If it's turns into a mess of knots, then stop before it gets too bad and add more detangler. Before you know it, the hairs are flowing smooth :). I tried coconut oil today, and ill probably go out there tomorrow to see how it turned out.
