"Our Pom Darby has BSD. For over a year we have watched his hair recede and his skin turn black, down his back and sides and tail. We tried everything we could find that people had suggested, and exhausted our vet's ideas. We had figured this was how he would be. Up until about 6 weeks ago, he was pretty much hairless down the back and sides and tail, except for some guard hairs.
It's been frustrating. We even contacted his breeder, who told us she has never gotten a report of BSD in any of her dogs.
We noticed that Darby was really itchy on the black skin. If you touched his back, he would jump and arch and beg to be scratched. Not only was the skin black, but it looked dry and scaly. My wife remembered using baby oil on babies for "cradle cap," which she said this reminded her of (except for the blackness, of course).
So just to try to relieve his itching, she rubbed a generous amount of baby oil into the skin on Darby's back. She let the oil soak in for about four hours. Then she followed that up with a coal-tar shampoo.
To our surprise, the black started flaking off as she washed him! So she continued to work it gently until no more would come off. The amazing part is that a few days later, where the black had flaked off, he started growing new undercoat. Now his undercoat is about a half inch long, and still growing fast. He still has a few patches of black on his shoulders and hips, and down his tail. so we are continuing this treatment about once a week to see if it will all come off.
Anyway, I thought I would share this with you. Maybe it will help others.
