It was hard to video while I was trying to motivate Sawyer to get into the pool but I got a few clips. Unfortunately in the first clip I didn't throw the tennis ball far enough so he didn't have to swim to get it.
Then I threw the bumper and had to get along side so he'd come towards me. Notice how he makes the detour on his way back out to pick up his bumper.
