Wanted to update you on my basenji's ear rash problems! Her ear flaps had turned black, tiny bumps appeared, edges & tips became crusty & sore. After 18 months of stupid vet visits, lots of money & meds, the 2 vets knew nothing. I did lots of research & tried many remedies, which sort-of worked, but not totally. I finally found a dog dermatologist. He said it was Vasculitis wherein blood vessels constrict & affected parts, starting with ears, begin to wither away from lack of blood & oxygen. Said it was from rabies shots. Said reactions usually appear 1-3 months after rabies shots. He said stop using the vet's meds asap! Then he prescribed Gengraf oral tabs 25mg. I researched Dog Ear Vasculitis, & seems like he's right. Anyone ever heard of Ear Vasculitis?
