He will be bouncing around with a new lease of life now with no creaking joints. I had the same thing with my old black Lab, 14 1/4, never had any real health problems and just literally went down hill overnight from old age. I like to think that she met up with her old friends.
The reason a dog has so many friends is that he wags his tail instead of his tongue.
