My guinea pig has a patch of what looks like dry skin on her right ear. I haven’t really noticed her scratching at it, but it never seems to get better. Anyone have any ideas of what this could be? My husband tried putting a small amount of hand creme on it to see if it would help and it just looked really red and sore the next day so we won’t try that again. I’ve looked up some information online and saw that they can get mites and fungal infections, but what Piglet has looks nothing like the pictures of those - as it doesn’t seem to be that pronounced yet. Any advice would be greatly appreciated.
