I have a dog staying with me at the moment. She cant stop scratching under her arm and its red. The owner told me that she has had problems with allergies in the past and has just come off steroids. She also suffers from pancreatitis but he said since they changed her diet and took her off the steroids shes been fine. She seems fine in herself. Would you advise to put anything on it? Ive tried sudocreme but she licks it off.
