What commonly characterizes the role of a draft animal?

The role of a draft animal is commonly characterized as that of a work animal. Draft animals, such as horses, oxen, and mules, are specifically trained and utilized to perform heavy labor tasks, most notably pulling loads or plowing fields. Their strength and endurance make them well-suited for these types of work, contributing significantly to agricultural practices and transportation in various cultures throughout history.

In contrast, other options highlight different roles that animals can play. Companion animals are primarily kept for emotional support or companionship rather than for labor. Service animals are trained to assist individuals with disabilities, focusing on tasks that help enhance their quality of life. Show animals are bred and trained for exhibition purposes, often competing in shows for aesthetic or breed standards rather than for work. Therefore, while each of these categories has its own unique characteristics and purposes, the defining characteristic of draft animals is their primary function as work animals in various labor-intensive roles.
