Breezy: My condolences on the loss of your brother. You are no doubt giving off mournful vibes and the dog is picking up on that. She is very aware of when you are thinking about your brother and his passing and she wants to let you know that she's there for you. You are her dearest and best friend and she loves you very much. Give her a hug and feel free to cry into her hairy shoulder -- she'll be fine with it and you will get some comfort from the release.
