I'm hoping maybe someone here has had a similar case and can help shed some light on this. I have an 8 yr. old male neutered dachshund. For more than a year he has had 2 large bald spots on his head. Skin is very shiny. No redness, no oozing. Just a large bald shiny spot. Then in the last 6 months he developed much smaller areas at various sites on his body. He had a moth eaten appearance. Never any itching at all. None of the spots seem to bother him in the least bit but he looks awful. Has had several skin scrapings and been placed on long term antibiotics. Nothing. Recently he was anesthetized and had 2 areas biopsied. They went pretty deep because he had sutures. Two specialists were consulted about the results or shall I say "lack of" results. One even asked my vet if he had been burned which of course the answer to that is absolutely not. There was nothing found in the results but the report says that his hair follicles are still present and in good condition. Just no hair is growing! The smaller spots that had appeared in the last few months are filling in but the large spots on his ears and head don't appear as if the will ever grow back. My other dachshund has always obsessively licked his head and ears but never his body. All blood work is normal. My husband and I are going nuts over this wondering what is wrong. Anybody?
Not hypothyroid, had him checked. Would a fungal issue have shown up in the skin biopsies? They did say maybe it was from some type of allergy. But how would I be able to tell from WHAT? I have another dachshund who does have skin allergies and if she is given regular dog food she becomes very itchy, licks her feet, and develops horrible ear infections. Chucky, my guy missing hair, does not display any of this. But you do have me wondering about a fungal issue.
I don't know whether a fungal infection would show on a biopsy. Usually the skin is scraped and then cultered in a special medium for ten days. As far as allergies go running an allergy profile is the way to determine whether he has them and to what specifically. Doesn't have to even be food related, it could be environmental.
Could it be as simple as maybe that your other dog is overgrooming him since you said she obsessively licks the areas where he is missing the fur?
