Help Finding Column, Please

[darklinensuit]

I expect I'm not the only one who remembers a famous Dear Ann Landers tearjerker column (possibly Dear Abby, but I don't think so) written from the perspective of a dog about to be put down.
It has the dog asking the owner not to leave him alone in his final moments.
This piece was reprinted in the column several times over the years, and I think it has also appeared on the Ledge (some time ago).
Of course, now that I want to share this particular column with a friend who just lost her beloved pet, I can't find it.
I have checked the official Dear Abby site & also Googled many different possibilities, all with no luck. I'll be grateful if anybody here can post the link!

Thanks in advance for any help.
