Regarding William (who is sleeping under my desk as I type this), he's a great dog.  Loyal,  Smart, and he loves to chase balls in the pool.  He has adapted well to his new environment, and has become rather friendly with his new sister Candee.  He is alert and makes sure to tell me if there is something he is concerned about.  He enjoys sleeping on his new dog bed, and enjoys going out to the dog park and (what else) chasing tennis balls.  He is a joy to be around, and I'm so happy that, even late in life, he has found his forever home.
