I'm truly sorry for you and your families loss BBJ, it really hurts when its time for your best friend to go on without you. While I know it's for the best, I always feel helpless and empty when they leave me behind, I worry about them and hope they're doing ok without me.
RIP Zoey, look around and see if you can spot Fred, Lew, Brown, Whammer and the new friends they have to play with, they'll make you feel welcome and not so alone.
I understand not wanting to get another dog because of the hole they leave in your heart when they have to go on without you. I think the great ones that make a difference in your life are the ones you miss the most because they were there when you needed them the most. I can't imagine not having a dog they make life so much better.
