    Has vet stumped

    In early fall, when I stayed for her grooming, I noticed my 10 yo rough collie Billie had a patch on her ear (back of the ear, in the middle) that was devoid of hair. She has so much fur I never noticed it until I saw her wet from her bath. It got a little larger but does not seem to bother her in any way. I thought demodex mange but the breeder said it doesn't run in the line, and the vet said that's not what it is anyway. It has, however, spread to her other ear, same place. Does not itch and she seems completely unaware of it. It has not spread to my other three collies. It doesn't have any crustings or anything, just looks pink. The vet's words were "I'm stumped, frankly." A scraping showed nothing, and a blood test showed nothing glaring. Any ideas?

    Sounds like ringworm to me -- or it's something the dog is rubbing against that has something fungal. It can be tough to diagnose (your vet may have used a typical light to try to diagnose ringworm but it can sometimes just be a weird variety of it and won't 'glow' under the light).  I would probably use something anti-fungal on it to start with.
