The thick hanging lips of a bloodhound or similar dog.He cocked his head quizzically and his tongue nervously lapped at his flews....
A Newfoundland's drop ears also keep out water, and very loose flews allow him to breath while carrying something as he swims.
The wolf ran his tongue along his flews like a person wetting their lips before the on take of some great feast; to break some fast that plagued his bitter soul.
