Swimming!

The dogs love chasing sticks and getting muddy.

Weasel bounds off the edge of the bank and quickly gets the stick, then Z-dog stalks her and steals it from her. There is lots of barking involved, and mud. Then they come up to me to deliver the stick and shake all the mud off onto me and bound off back into the river.

Sometimes Weasel goes far afield to avoid her stalker.

And, sometimes, she prevails.
