Throughout their life together, Cosmo and Devo always had the ball control thing clearly worked out in their minds. Cosmo had it, Devo wanted it. As you can see, it started early. Devo was ball obsessed. Cosmo acted like she didn't care, but always ended up with it. Cosmo could never out run Devo for the ball.....never. Didn't matter, because somehow she could trick him into relinquishing anything he was retrieving. When Cosmo got older and really slowed down, he would drop the ball short so she could pick it up and carry it the rest of the way. It's just the way they thought it was suppose to work. That was just fine with me.
