I had a golden retreiver that loved to splash into the water after a ball. When I decided it was time to leave the park and I wanted her to start drying off, I started throwing the ball NOT in the water. She would get the ball, look at me as if patiently teaching a child, then go to the water and lay down in it looking at me, then come give me the ball.
It was as if she was trying to train me “Throw the ball in the WATER!!!”.
That reminds me of when our little Blue Point Siamese mama cat toilet-trained her kittens by the lecture-demonstration method. Hilarious!
