That is all i can say.. is wow, there is no words to describe how hurtful that video is, Not all equestrian's are like that, and i feel like they are blaming the whole equestrian community. I would never do anything of that sort to my horse, and anyone who does, need's to be more educated..
I do find that they need to more educated on tack and equipment, (person who made video) About martingale's and whips and spurs etc, they only harm, if they are used inappropriatly. They were not made to specifically inflict harm upon an animal, or living animal.
Hopefully people know better than that
