Hello & welcome, I am Dr. B, a licensed veterinarian and I would like to help you with today. I do apologize that your question was not answered before. Different experts come online at various times; I just came online, read about your wee one’s situation, and wanted to help.
Again I do apologize that my colleagues could not aid you sooner, but can you tell me:
How long has she had these signs?
Where on her body is she chewing her fur?
Any changes to the skin (ie pustules, pimples, sores,ulcers, dander, crusting, etc)?
When did you last treat for fleas and what product did you use?
Any diet change in the months before this started?
Any changes to her breathing or does she seem sore anywhere (ie around her rectum, back, legs, etc)?
