I just figured out why my Pom's fur keeps getting discolored. It's the dog tag. We got a new town dog tag (new one every year), and this year's is somehow rubbing off on his fur and turning his creamy white fur into an ugly dirty gray. I don't wanna take it off forever 'cause I'm afraid he might need it (He does have another tag with name, phone, and address, but I dont know if the town requires the town tag).
So I thought maybe I can give it a coat of clear nail polish or something to keep it from rubbing off. Is this a good idea? Or is there something else I could do...
