The Rainbow Bridge story is one that I always pass along to those that have lost a pet. Good find May Day.
I remember when we put our lab, Tex, down. My best friend and neighbor was Tex's vet and I don't know who cried more - he or I. Later that day he came over with some Midleton Irish whiskey. Even the wives got a shot. We did some damage to that bottle.
My heart is out to you Sage. Just remember to be the kind of person Sadie thinks that you are.
