I'm sorry for the horse. I suspect the reason why some Freepers came in with slant remarks is because the grieving here is from the Editors of the New York Times.
I have memories of dogs who have died. I used to ride when I was younger, but I haven't ever had direct experience of putting down a horse.
Anyway, my sympathies run both ways. It's sad when a great horse suffers like that. And it's also sad that the Times cares more about animals than human beings.
bingo.
