Firsts: The pounce! The pup leaps forward
all four paws off the ground, and lands a couple inches
from where he started. It's quite cute to watch.
Also, for the first time the whole crew came across the
floor to me when I called them "pup! pup! pup!".

The "running" is getting more coordinated. Most times now,
the rear end moves at the same speed (and in the same direction)
as the front end. :)
