The horse with a bull neck has a short, thick, and beefy neck with a short upper curve. The attachment to its body is beneath the half-way point down the length of shoulder. This trait is fairly common, especially in draft breeds, Quarter Horses, and Morgans.
With a bull necked horse, it is generally more difficult to maintain balance if the rider is large and heavy or out of balance, which causes the horse to fall onto its forehand. Without a rider, the horse is usually fine.
A bull neck is desirable for draft or carriage horses, so as to provide comfort for the neck collar. The muscles of the neck also generate pulling power.The horse with a bull neck is best for non-speed sports.
