Since there don't seem to be a lot of bugs in your area, it sounds to me more like allergies. Cincy gets scabs on her skin from itching, and she will chew/lick all the fur in areas off. They have been much better recently, and her fur is fianlly growing back. I don't know if it has been the food, vitamins, Benedryll or combination, but we finally seem to have found a "program" that has her allergies under control.

Hope Nebo feels better soon
