Hello & welcome, I am Dr. B, a licensed veterinarian and I would like to help you 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.
If you would still like assistance, can you tell me:
How long have these been present?
Are they itchy for Cupid?
When did you last treat for fleas? What brand did you use?
Is the hair falling out over these lesions?
Can you take a photo of this? If you can do so and post them online, it will let me see what you are seeing. To post them, you can either use the paperclip on the tool bar. 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 address here for me to have a peek.
