HI and thank you for your post! I see the pictures which show hair loss around the tail base and ears. If he had been itching these areas, I would be suspicious of flea dermatitis. All it takes is one flea to induce a flea allergy. Fleas love to hang out around the areas and the tail base region. Using a good quality flea preventative product will help treat and prevent fleas. If fleas have been completely ruled out, a fungal or bacterial infection may be at play. Seasonal allergies is another possibility. The areas are darker due to chronic inflammation and may return back to normal skin color once healed. Percy's veterinarian can run a few simple skin tests to rule out fungus, mites, or a bacteria as the cause. A flea preventative product will help rule out fleas as the cause. I hope this has helped answer your question. Best of luck to you and Percy.
