Animal packs, also known as pack animals or beast of burden, are a type of transportation that utilizes domesticated animals to carry goods or people over long distances. This method has been used for centuries and continues to be a popular mode of transportation in many parts of the world. Pack animals are typically large and strong animals such as horses, mules, donkeys, camels, llamas, and oxen. These animals are trained to carry heavy loads on their backs or sides, making them an efficient and reliable means of transportation in areas with rough terrain or limited access to motorized vehicles.
