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 is she overgrooming specifically (ie neck, belly, etc)?
Are you seeing any changes to her skin (ie pimples, pustules, scabs
, sores, ulcers, redness, dander, or crusting)?
Even if you do not see them, when did you last treat for fleas? What did you use?
Any recent diet changes in the 4-6 weeks before this started?
Any changes in routine, pets, people, or anything in or around the house?
