I have seen many of my beloved buddies go to the Rainbow Bridge in the past years - it never gets any easier. My vet and her staff try to make it as peaceful as they can. I never leave their side and I talk to them throughout the procedure (a cold word I know). I tell them how much I love them, how much they mean to me and I always tell them to go in peace - which they do. When the time is right I write them a letter and I put it with their ashes. I look for signs that they are okay - Squire sent me a rainbow, Hondo a full moon, etc - silly I know but these things help make it easier for they mean so much to me and fill my life with such joy.
