There's this white crusty stuff on my Thoroughbred's tail bone, it seems like it could be dandruff but its very thick and crusty. Its really weird and im kind of concerned. I discovered it yesterday when I was braiding her tail.
My mare has a dry tail bone as well. I normally just ignore it in the winter. In summer I make sure its washed really well when she gets her bath. I even take a rubber scubber to it to get all the scales off. Then I rub in some MTG and continue its use until her next bath. The MTG is pretty much the only thing I have found that helps.
She isn't bothered by it, it doesn't seem to itch or pain her. It is unsightly when her tail is braided up though. Especially with her black tail
Thanks ill have to do that when it gets to be summer, I've never noticed it in the winter before, but then again I never had a thoroughbred mare before during the winter. Last winter I had a thoroughbred gelding but I never did braid his tail during the winter. Ill just have to take care of it when it gets warmer out.
