i noticed this morning that my 16 week cavalier had some fur missing above her right eye to the side of her tan mark. There is even more missing tonight and i can see a very small cut or spot there. She has not been scratching the area as far as we know unless she does it in her cage at night, the rest of the time she is always with us. Is it just an irritation or is it some kind of mite? Should i pop her to the vets or just see how it goes?

I would also check her ears, my boy has an ear infection at the moment and he's got a bald patch near his eye where he's been rubbing his head along the wall!
