Hi Jake. What a grand gentleman you must have. How long have you had him? When you say just noticed, do you mean today, yesterday, few hours ago? Is there any discoloration? Does there appear to be a break in the skin? Is there any indication that it is bothering him; trying to scratch at it, or trying to rub it on anything? Have you seen any discharge from nostrils or eyes? Have you seen any changes in any of his behaviors at all? This extra information will help me give you my best advice. Thanks, Patricia
