The last time I saw my brother and sister in law and their dogs, I had a feeling that something was up with their black lab mix. She seemed like she was getting old and since she is part retriever, I had a feeling that she wouldn't live long. I found out today that when they woke up, their dog had died. I don't know if I have a sixth sense about these things or if it was because her back legs were starting to atrophy with old age. She wasn't that old. A sad, sad day.
