Hair loss?

For some reason, Darcy has started developing bald spots on the backs of both ears. They match! There is no redness, no sores or wounds. I have no idea why she would be losing hair on the backs of both ears

Any ideas? pics to come in a little while.

could be a mild allergy .... could be a mite issue...

best bet call and describe to VET not the receptionist

I hope it isn't mites....
I will call the vet tomorrow...thankfully I have the most wonderful vet in the world

Here are pics anyway:
