Well, I'm guessing that Tobie (the dog) has also done some of that same reading. Yesterday while Zeke was hanging out in his swing, she decided to start training him to play ball with her.
She very gently dropped the ball directly next to him in the swing and then waited for him to throw it. I'm not sure how long she would have waited. :)
I then had to tell her to he wasn't quite ready to play catch with her and to retrieve her ball as seen by this picture as Zeke looked on.
