My thoughts are that 9 lbs. in one year would be normal if he is getting more exercise and less food.
As long as he look to be of normal weight and is still acting healthy I would feel ok about it for now. No, I would still worry, but that's me! LOL! Logically it makes sense though.
I would run a CBC anyways. Whether the vet said to or not, but then again that's always one of the first things I do when one of my dogs is sick. My vet doesn't recommend them to me either, he just knows I'm going to want one.
