Together to the very end

I saw this story awhile ago, and I like it a lot. I agree that people are too quick to put their dogs down sometimes. I understand putting them out of their misery if they are hopeless, but at the same time, just because a dog is getting older, doesn't mean it's life is up. What if someone said to you, oh, you're getting old, you're 50. You've lived long enough. It's like, hey wait, I have many good years left!
