Kris, I am sorry about Big Boy. I understand the heartache of losing a beloved pet. Right now my momma dog is almost 13 and I can see the decline in her. I keep saying a prayer that she will stay around a few years longer but I know that at her age anything can happen. So sending some big hugs. I pray when the time is right, you will know that you are doing the best thing for him. Hugs, Marle
