Beast of burden

A pack animal or beast of burden is an individual or type of working animal used by humans as means of transporting materials by attaching them so their weight bears on the animal's back, in contrast to draft animals which pull loads but do not carry them.

Traditional pack animals are diverse, including camels, goats, yaks, reindeer, water buffalo, and llamas, as well as the more familiar horses, donkeys and mules.

The term pack animal is traditionally used in contrast to draft animal, which is a working animal that typically pulls a load behind itself (such as a plow, a cart, a sled or a heavy log) rather than carrying cargo directly on its back. For instance, sled dogs pull loads but do not normally carry them, while working elephants have been used for centuries to haul logs out of forests.

Traditional pack animals include ungulates such as camels, the yak, reindeer, goats,water buffalo and llama, and domesticated members of the horse family including horses, donkeys and mules. Occasionally, dogs can be used to carry small loads.
