Fetch Revisited

Today, Flash and I played fetch outside. I threw the tennis ball with the cookie inside and he readily chased it--two times. On the third pass he settled down to chew up the ball and get the cookie himself. So I got his retractable leash and tried again. This time he returned the ball every time and I didn't have to tug on the leash at all. After a few times, I took off the leash and threw the ball a couple more times. He brought the ball back every time.
