Aw, you sound to be a very caring owner. I'm not sure what this is from here; a small lump or tumour, midge bite / flea bite / flea dirt, a spot of occular or nasal discharge, could all be on the list. A scab would soon drop off. However, I can tell you that your vet may well be able to prescribe something that will help with the midges - and at the time time have a quick look at it so that if it is attached / part of the skin, they can let you know their procedures for finding out more.
