When is a horse too old?

[my miss storm cat]

Stormy Do was euthanized yesterday.

He was 13 and had broken down at Philly Park. I'm not sure how many starts he had had, but I know it was somewhere over 100.

So this is my question.....

Once upon a time, on a forum far, far away, I got my head handed to me for suggesting that Bluesthestandard should be retired. it was partly due to his age, but my main argument was that he'd been injured so many times and had dropped down so far..... it was a matter of both fear and dignity.

I was told I know nothing.

Okay, fine. I don't pretend to know...

I was informed that if i were an owner, I'd see it in a different light.

I can live with that argument.

Sure, there are older guys around..... Proven Cure being the perfect example of an old warrior (he's 12) who is sound and loves to run, still has it in him. He's owned by the connections of Perfect Drift... people who clearly take good care of and adore their horses.

When, though, is a horse too old? I'm just curious as to your thoughts. Thirteen years old and over 100 starts..... am I wrong for finding it troubling that he was still out there?

Rest in peace, Stormy. It's a shame..... you deserved a nice retirement.
