Poor Coco! There are a number of things that can cause red, itchy patches on the skin along with a greasy coat (seborrhea) - the most common possibilities would include allergies, a bacterial or fungal skin infection, or skin mites (mange). If your vet has not been able to make a diagnosis, I would suggest requesting referral to a veterinary dermatologist or seeking a second opinion from another local vet - there are tests that can be done to help determine the problem, which is important in order to make sure that you are treating it effectively.

    It looks like coco has been very itchy. I would be concerned that coco is suffering from allergies. The most common type of allergies are flea, food and environment. I would recommend taking coco to a veterinarian for skin medications. Make sure you are applying flea prevention monthly.
