My Chachi had demodex when he was one. It was awful!!!! At first the vet thought it was a flea allergy so he treated him with steroids. After a couple of weeks it wasnt getting any6y better so he did a skin scrape and found out he had mites. At this point Chachi was in pretty bad shape he had sores all over his back it was inside his ears and almost all the hair on his back was missing. He had to have these dips that the vet tech gave him. He was supposed to have 6 dips 10 days a-part. After the 5th one he became sick from them and we had to quit them but the demodex was cleared up anyway. He hasnt had a problem with them since and hes 4 1/2 now |
