Beasts of Burden

Donkeys are long-eared, horselike creatures. They are surefooted and sturdy, and can be taken into dungeons or caverns. The statistics presented here could also describe burros. A light load for a donkey is up to 70 pounds; a heavy load, up to 140 pounds.
Draft Horses include large breeds of working horses such as Clydesdales. These animals are usually ready for heavy work by age three. A light load for a draft horse is up to 350 pounds; a heavy load, up to 700 pounds.
Riding Horses include smaller breeds of working horses such as quarter horses and Arabians as well as wild horses. These animals are usually ready for useful work by age two. Riding horses cannot fight while a rider is mounted. A light load for a riding horse is up to 250 pounds; a heavy load, up to 500 pounds
War Horses are trained and bred for strength and aggression. They usually are not ready for warfare before age three. A light load for a warhorse is up to 350 pounds; a heavy load, up to 700 pounds.
Mules are sterile crossbreeds of donkeys and horses. They can be taken into dungeons or caverns. A mule is similar to a riding horse, but slightly stronger and more agile. A light load for a mule is up to 300 pounds; a heavy load, up to 600 pounds.
A Pony is a small horse, under 5 feet tall at the shoulder. Ponies are otherwise similar to riding horses and cannot fight while carrying a rider. Ponies can be trained for war, and the morale in parentheses above is for a war pony; this does not allow them to fight while carrying a rider. A light load for a pony is up to 275 pounds; a heavy load, up to 550 pounds.
