Bradley is getting to the stage where he needs a lot of exercise or he misbehaves. Mostly he barks at Brodie. It's the high-pitched, "play with me" bark. But a 70 pound lab is loud even when it uses a puppy bark. He still refuses to fetch so our main exercise for him is walking. Today he got 3 walks. Rob walked Bradley this morning. I walked both of them this afternoon and then Rob walked them both again this evening. It's amazing the difference in his behavior when he gets a walk.
