Thank you for submitting your question regarding Merlin. If the rash has been present for several weeks, then he needs to see his veterinarian. He may need medication or a diet change. Sometimes irritation along the mouth can be due to a food allergy or intolerance. He should also have his teeth evaluated as I can see a retained baby tooth in your picture. This needs to be surgically extracted under anesthesia. I hope this information helps!
