wetware: Do yo have any idea how many racetracks there are in North America? let alone Asia and the rest of the world.An average racing card is say 10 races,with on average say 8 horses.Based on your calculations,my local track would have(for small) 1 euthanization a week?

Horses get bumps and bruises just like any athlete,and sometimes they never race again,but very very very rarely are they euthenized,and frankly,just like in Barbaro's case,it's to save them a painful death.

I haven't seen this issue raised often,just like those who say "kill all the rotwieller's" when a death occurs,it's knee jerk reactionary behavior.
