There's so much controversy about this. There are those who say a horse will do what it wants to do. In this respect, diving is better (meaning the horse wants to dive) than being sent to auction as meat. But I might convey the wrong message here...lots more to be said.
I have mixed feelings about this. It sounds like the last time it was done the horses were basically forced off the platform. I'm also not sure twelve feet is actually deep enough for something the size of a horse to dive into safely.
IF the horses are properly trained, well kept and they increase the depth of the pool, I could handle it. Yeah. Very mixed feelings.
I can see nothing, but cruelty and barbarism in making horses to this. It would be done purely for , probably, greed. You can bet that there will be betting on which horse goes furthest. Ugly thing to expect them to do.!!
