Just because she is 9 doesn't mean she won't be active and play with Champ. I have a 9 year old and he regularly plays with thw 2 year old and the 9 month old. It may be that you end up considering a third in a couple of years but being 9 does not equate to not being playful. That is part of what makes it so sad. If you watch the Veterans classes at events you can see how much older Bs really love to get out do the things they used to. My Nicky loves to go in the ring with his "Aunt" Pat as a Veteran and show off. Of course it depends on the dog. Each one is an individual.
I would also be wondering if the breeder was notified. Did they give her registered name?
