Hello, I am afraid that the expert you have requested is not currently available. Still I am Dr. B, a licensed veterinarian and I would like to help you with your wee one today.
How long has she been refusing dry food? Will she eat wet food?
Did her teeth fall out, break, or were removed?
Any pawing at her mouth, dropping food when eating, drooling, vomiting, or gagging/retching?
In regards ***** ***** nose, any sneezing or nasal discharge?
Can you take a photo of this scab? 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.
