Lara, this is the worst possible position to be in, knowing that you have to help Barney to the Bridge but not knowing just the right time. When I was going back and forth w/Puddy, even when I called my vet and said that I was on my way in w/her because she couldn't breathe, the sweet little girl still walked over to her food dish and tried to eat some chicken before we left. It was heartbreaking. Once this is all over, though, you'll take a sigh of relief because you'll know that Barney is at peace and in no more pain and the awful demon of indecision will be off your back. As you know, we're all there w/you in spirit, holding your hand and stroking Barney every step of the way.
