Thank you for your question about Oreo. Dry skin on the ears of guinea pigs is very common, and you may also see flaking of brown debris from within their ears as well. This flaking is their normal cerumen (ear wax) and it just tends to be brown to black in color, depending on the color of your guinea pig. For the dryness, I am not sure why you are seeing it only on one ear - sometimes if one ear is black (or dark in color) and one is white (or light in color) that it is easier to see the dry skin on one versus the other. To help with the dryness, you can rub a small amount of Aquaphor ointment on the ear. This medication is used for eczema in humans and can help hold in moisture. Apply it very sparingly, and if Oreo is bothered by it at all, I would recommend discontinuing it. Less commonly, guinea pigs can get skin infections of their ears. If you see that the flaky skin becomes crusty, red, swollen, has a smell, or if Oreo is bothered by the ear, I would recommend taking him to a veterinarian. They would be able to evaluate the ear and may take samples of the skin surface to look at under the microscope. If they determine it is an infection, they can prescribe treatments such as antibiotics and pain medications. I hope that gives you a place to start, and good luck with your new pet!
