Question: is bobtail the name of the horse?
Answer: This is sometimes misheard as “Bells on Bob's tail” or “Bells on Bobtail,” as if Bob or Bobtail is the name of the horse. But bobtail actually refers to the style of the horse's tail—a tail cut short, or a tail gathered up and tied in a knot, which you sometimes see in dressage events these days.
