Denise, I dont know why it couldn't have been a sign, in fact I feel it was. What you did for your mom's dog playing the video and being there for her was really sweet and caring of you, I know it was not easy having to let her go but you did the right thing for her, when their quality of life is gone its the humane thing to let them go as hard as it is and you did that. Im sorry for your loss, your mom and her dog are now together and happy and healed. Take care
