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.
Again I do apologize that my colleagues could not aid you sooner, but can you tell me:
Are you seeing any pus, discharge, or is there odor from the non-healing comb?
What does her stool look like?
What color are her gums/oral tissue? Pink, pale/white, or yellow tinted?
Any access to toxins or history of injury?
Any belly distension, leg issues, fever, or breathing changes?
Can you take a photo of her comb for me? If you can and post them, it will let me see what you are seeing. To post them online, you can use the paper clip icon above your text box. Or if you cannot see that on your phone/computer, just post them on any site (ie Flickr, Photobucket, Imgr etc) and paste the web link here for me follow.
