I Think Barbaro Should Be Put Down

The advances today are absolutley amazing horses that would have been put down 5 years ago are now treatable even broken legs can be fixed ( used to be instant death sentence) ive seen alot of horse injuries from ripped out legs to lighting strikes & it has allways amazed me the massive healing power of horses so i wouldnt be giving up on the horse just yet .One thing you can be absolutley sure of the vets treating the problem would not continue if they thought there was no hope or the the horse was in absolute pain.
Just wondering do they feed horses alot of sellium over there? laminitis is becomming quite rare down here.
