Tonya this is so sad and I understand completely what your grandmother-in-law is feeling. The fact that Charlie was able to run up to the door, wagging his tail says so much about what dogs are all about, doesn't it. As sick as they may get, they still love the sound of human visitors at the door. I know when my Ashley (RB) was so very sick she still came to the door with a wagging tail even though she was too sick to keep any food down. I will pray that when it is "time" your in-law will know. (((Hugs))) to all of you and especially Charlie. This is just heartbreaking.
