Have you ever had a dog euthanized?

Wow, that must have been awful.

I have had to make the choice to do it before, but it was because of pain. One had gotten old and had ailments that put him in pain constantly. The other had been injured to the point that they wouldn't be able to save him, but that he would continue to live in pain for a few more days as he slowly died. I just couldn't stand the thought of that, so we let him go.
