heh, well she's a big girl. So when she first gets there she'll run around with them for about 2 minutes. Then she'll find a nice cool wall to lay against and stay there until either:
a) A dog comes up to sniff her
b) A new dog comes in the room
c) A new person comes in the room
d) The pee mopper (one of the two humans in the room) starts handing out treats
She's normally pretty good about sharing/interacting. It's just pools and large water bowls that she gets greedy about.
