If I saw a chance, I'd try to save it. If not, I'd kill it. I know it sounds cruel, but if it's too late to save it and he's dying slowly, it's better that way in my personal opinion.

I would at least try to make it's last moments worth living. Get it some food and water and a place to sleep. I'd probably take it to the vet then and have it put out of it's misery... I really hope this never happens to me.

Put it out of it's misery of course. That goes with any animal that is unable to be saved, not just a dog.
