We live in Florida a typically hot and humid place, lately it has been dry and cold. This is when Benjamin has started his new problem. He is itching and biting like crazy. He is itching so much that he he is causing himself to bleed. We don't have fleas, and we haven't changed his diet. We know that we have been dealing with extremely dry skin ourselves (lack of moisture in the air) and we believe that this is his problem. Is there something we can put on him to soothe his itchiness?
