Sorry for your loss. I have been there too. Praying the night before that he would pass in his sleep, but it was not to be. The girls came home from college the night before and slept with him on the floor. His kidneys had failed and he was going downhill quickly. We took him to see some people around the neighbor hood so they could say goodby. The vet came to our home to make his passing as peaceful as possible in front of the fireplace in the living room. It has been 6 years and still chokes me up. I always told him I wouldn't let him die alone and kept that promise. Bless you for letting your friend die with dignity.
