I love this one, she just made me grin:

I'm not looking for a third dog. I've only considered it because sometimes my 5-year old still wants to play and the 7-year old doesn't... but she either runs around the yard like a crazy thing or we play with her instead. Or both.

Good luck on your search! It's fun, really.
