* A horse with a very short tail: This could be due to genetics, injury, or a cosmetic tail cut.
* A horse with a tail that is held high and straight: This could be a result of the horse's conformation or its temperament.
It's important to note that horses with short tails or tails held high aren't necessarily "bang tails" in a specific sense. If you're interested in learning more about a specific horse, it's best to ask the owner or a knowledgeable horse person for more information.
