Bald Spot

[user 14499]

My chinchilla has developed a small bald spot on his nose. I googled what this could be and some people said it was just from rubbing his nose between bars on the cage, but other sites said he may have a fungal infection! I don't know if I should be worried or not. He generally sticks his nose between the ~1 inch gaps in bars often when he hears me opening the bag of hay. He is acting normal otherwise. Should I be worried?

It looks very typical of a fungal infection, most commonly ringworm. The nose is one of the most common places it pops up. Is the skin dry/scaley at all? If you search the forum for ringworm treatments you will turn up plenty of suggestions. If those don't work then I would make an appointment with a chinchilla experienced vet.
