I'm sorry that your question wasn't answered in a timely manner and I regret that I'm not allowed to correspond with customers by phone. Can you upload a photo of these spots to our conversation? You can use the paperclip icon in the toolbar above your message box (not if you're using the chrome browser) or you can use an external app such as imgur.com or dropbox.com. I can be more accurate for you if I can see what you're seeing.
Is Billy pruritic (itchy) and licking these spots? Are the spots isolated to his haircoat or do they involve the skin or both? Do they come and go?
