My 10 month old english bulldog was neutered on 2/24 at the Humane Society of New York and two weeks later he developed this red spot with hair loss on his rope wrinkle across his nose. We immediately took him to the vet and were told she thought it was ringworm. I did some research and I thought it looked like demodex mange, but I didn't take him to the vet and my boyfriend never relayed this. The vet took a skin sample and told us she would give us the results in two weeks. She gave us some topical ointment to apply - though it hasn't gotten better, it hasn't gotten worse either. I also noticed some redness on his chin and they looked like pimples. We called the yet yesterday and she said to bring him back because she thinks it might be mites (which irritates me because I'm not even a vet and I suspected this). My question is, is there a correlation between lack of testosterone and demodex mange? Also, is there a possibility this could be a hormonal allergy? I guess I will find out today if it is mites, but I want to have all of my info ready because I am not in the mood to shell out another $150 in two weeks because they were wrong again. Thanks for your help!
