What core biological feature firmly anchors the red fox in the *Canidae* family rather than *Felidae*?

Answer

A longer muzzle and different tooth structure adapted for crushing

The definitive placement of the red fox within the dog family is cemented by its core biology, which is less apparent externally than appearance or behavior. Canids, including the red fox, typically possess a longer muzzle compared to felines, and their tooth structure is generally adapted for crushing and processing a more generalized diet. The text notes that their dentition reflects an omnivorous tendency typical of many canids, contrasting with the highly specialized dental structures of many true cats.
