That's so sad - I'm ceying right now just thinking about it. While I've never had to put a pet down, I've lost quite a few to "just taking off" or getting hit by a car (just one of those). I hink that having to go through what you just did is way worse. Read that Rainbow Bridge poem - it will make you feel better. And if you're lucky, your Rotty will visit you in your dreams. It sucks right now, but it will get better.
