Bailey is like some of the other boys -- he runs in and drinks copious amounts of water. Then he usually likes to flop down somewhere cool.
Grace wants to do whatever B does, so she also drinks a lot (I have to put the water bowl up constantly), and then she wants to PLAY! with B. But that has nothing to do with walks, it's what she always wants to do.
So sometimes she has to go to her crate for a nap.
