Flews, or the thick fleshy lips of certain animals, has several synonyms that can be used interchangeably depending on the context. In zoology, the term "labia" is often used as a synonym for flews, particularly when referring to the lips of carnivorous mammals such as dogs or wolves. Another synonym is "jowls," which is commonly used to describe the sagging skin under the lower jaw. "Muzzle," on the other hand, generally refers to the entire snout of an animal, including the lips, nostrils, and jaw, but can also be used to describe the flews specifically. Other potential synonyms for flews include "cheeks," "chops," and "face".
