Same thoughts here. I don’t know why broken bones in horses legs and ankles can’t be treated like other animals. I understand why a horse might not be able to race again, but I am sure that the owners would rather have their horse living happily in retirement from the sport. I’ll have to ask my brother who is a Veteranarian.
I’d be curious to hear your brother’s answer. I think it is because you can’t keep them off their feet long enough for the fracture to heal, but I’m no veterinarian. I stayed at the Holiday Inn once a few years ago, though.
