Such a sad story. Glad it has a happy ending though.
My Mom died sitting on the sofa and her dog stayed right next to her until my poor Dad realized she was dead. Poor Dad did not even realize he should call 911 - he went in search of the family doc who lived on the next strret! Doc wasn't home so he came home and went to the neighbors and told them that he thought his wife was dead. They called 911 for him. I then inherited her dog as my Dad really couldn't take care of him.
