I agree with KigerQueen, I don't like a mountain of a horse standing on his tiptoes. A horse that size should have a good leg under him.
It's a crime what halter horse breeders have been doing for years. They are not responsible, thoughtful people, in my opinion. They are breeding disposable horses who have limited uses. The only thing those people seem to care about is titles and money. But a horse can live for 30 years +, and should have a happy life. Halter horses like the ones KigerQueen displayed are destined to either breed more useless halter horses, or be sold to the kill buyers, if no one dumb enough to buy them for riding can be found, it's just incredibly sad.
