I would't name it anything cos I don't believe in torturing horses ( animals) for our greed & profit.People show phoney love & affection when they win but when they lose or if the animal is hurt then they just put them down & that's it.
Shane, I believe your knowledge of anatomy of racehorses, or horses' in general, is limited.
When a racehorse is hurt, beyond healing, yes, it's euthanased. This is to stop pain & suffering of the horse. It's NOT a 'whimsical decision' like you make it sound.
There's usually two EQUINE Vets consulted, BEFORE that decision is reached.
I wouldn't wish on anybody to see the suffering of an injured horse. It's absolutely horrendous. Been there, done that, several times. It's my love for these totally majestic animals' that keeps me going!
