One of the gentlest and most intelligent horses I have ever known was a Belgian and her colt, owned by a friend of mine in Fort Bragg California(which is really not a fort but a small town and home to a sh** load of liberals). Friend wasn’t a liberal and is dead now, but the memory of those two gentle horses, so huge, pulling wagons for carolers to ride on at Christmas eve and in town for tourist on holidays lives on.
A friend of mine had a 17 hand Mule, she was too big to comfortably pack, this horse is a foot taller at withers, yikes you would need a step ladder, good thing the draft breeds are good natured
