One thing you can do to help his coat is to bathe him every 1-2 weeks with Murphy's Oil Soap. Use your fingers and gently "scrub" him while he is soaped up. (Murphy's does not produce much lather so don't expect it.) The massaging will loosen dead hair and help it fall out. This stimulates new hair to grow. Murphy's has natural oils including coconut that help moisten the skin and keep it healthy.
