My dear friend. I want to make sure you have mastered
the art of stopping on a dime. This skill is very important
when playing with another dog. When you are running at top
speed you jam your front feet into the ground. This will
cause you to stop and send the other dog flying past you.
If you do this at the beach you have to be careful of the sand.
Also, don't try it with Della, she's too fast.
