I am a new puppy owner to Charlie, an 11 week old labradoodle , and I am wondering about games to play with him. I don't want to encourage tug-of-war, and we've tried tossing the ball, but he generally isn't interested in that. Usually, he chews on his toys and then when he's really wound up, he'll "wrestle" with his stuffed animals. Any suggestions on how we could interact more? thanks!
