Mule

Mules were pack animals, a cross between horses and donkeys, specifically bred for the purposes of labor.
Mules were bred with the intention of sharing the best traits of its two parent species. They were more sure-footed, hardy, and longer-lived than horses. Compared to donkeys, they were faster and more intelligent. However, they were an infertile species.

These creatures were often herded among other grazing beasts in order to protect them from wild predators, such as coyotes or wild dogs.

Mules are well accustomed to eating grass, requiring no separate fodder.
