Oh yes, Chiquita LOVES ears too! She will lick, and lick, and lick, and lick, and lick, frantically all the way into your ears!!! It is soooo gross! As for your issue with your chi rubbing his bum on the floor, I would have the vet look at him, some chi's have a problem expressing their own anal glands and they might need to be expressed again. Or it could be a sign of worms, so on the safe side, I'd have the vet take a look.
