I think my horse is an ESTJ. He loves being around people and other horses -- definitely draws his energy from that; he's always checking out any changes in his environment and doesn't really see things that don't exist -- definitely a sensing horse; he's not reactive and definitely thinks about things; and he has many opinions about everything from his schedule to his feed -- a judger, if ever there was one.
Boy, this is a tough one. They show so many different personalities and sometimes, they change. But it will be something for me to have fun with, as I watch them. Love the great picture, with this article.
