I guess you would consider this heroic, I do:

Last year our chow (Rainbow Bridge Keisha) died from bloat.
I was getting ready for work, and all of a sudden Angus started barking & howling like crazy. He NEVER just howls, barks sometimes, but never howls. So I went to see what the problem was. I opened the door & he was just going crazy trying to tell me something. So I look around for Keisha & all of a sudden I hear the most awful noise, my girl was crying in pain. She was under a trailer we had out back. So I called her & she moved like she was in alot of pain (which she was). Anyway to make a long story short (and without making myself cry) I would have left for work & not known anything was wrong with Keisha if Angus hadn't told me.
I find that pretty heroic!
