Which of the following taxa would you not use to classify the coyote?

Explanation: Vulpes is a genus that includes foxes, which are distinct from coyotes that belong to the genus Canis. Therefore, Vulpes is not used for classifying coyotes, while the other options (Canidae, Animalia, and Canis) are relevant to their classification.
