Well, as the saying goes, If you hear hoofbeats, don't think zebras. After consulting with my vet, and a day and a half of washing his nose with warm water and applying quadritop ointment twice daily, most of the funky skin is gone. His nose is looking normal once again.

I hope that does it for you. I had a nine month old pup with the same issue...vaseline/vit E "fixed" it for a while, but the rough skin would come back and then she lost pigment as well. Good luck!
