[Ravens Keeper]

I took Raven to her first grooming appointment today, and as soon as the groomer saw her, she was like "Oh she is so cute, but she has crud."
She pointed out to me that on the top of Ravens nose there was a little bald spot with no hair, and on the sides of her nose there were little bald spots.
She was saying this is common with yorkies and toy poodles. She said to call the vet. Has anyone ever dealt with this??
