Why is my dig always do itchy!!? She doesn't have fleas...?

Is she scratching at her ear's specifically? That might be caused by Ear-mite's.. If she's scratching wildly around her body it could be her type of fur is irritating herself,not much you can do there...I'm still going to lean on the Ear-mite theory. I'm not really sure how to solve ear-mite's, but that's why we alway's have google!
