Hello & welcome, I am Dr. B, a licensed veterinarian and I would like to help you with your wee one today.
Any changes to the skin (ie pustules, pimples, redness, crusts/scaling, ulcers, or sores)?
Any diet change in the 2 months before this started?
Is she worse at any particular time of year?
What flea treatment did you use? When did you last apply it?
Can you take a photo of this to let me see what you are seeing? To post a photo, you can use the paper clip button on the tool bar above the text box. Or if you cannot see that on your phone/computer, then you can post them on any site (ie Flickr, Photobucket, Imgr etc) and paste the web link here for me to have a peek.
