So sorry LB. Don't ever feel shy about expressing grief over a beloved pet. They are worth every ounce of love we can give them and that love naturally results in terrific grief when we lose them. I have loved many animals over the course of my life so far. It hurts so much to lose them. They really are like furry family members.
It's natural to feel like you will never want another dog....you may even feel that wanting another puppy would be a betrayal of Blue. Of course, it wouldn't. I always tell people who have lost pets to take their time to mourn them, but that the love for animals that is in their hearts should not go to waste. Some other wonderful dog will come along for you now that Blue's stay with you is done. When you're ready, make room. Animals need good persons who will love them as much as you obviously do.

P.S. I love the idea of the Rainbow Bridge. But my god! I'm a little frightened over what my greeting there would be like....Noah's Ark revisited. lol
