I thought this would be an entertaining topic. What does your dog do to tell you that he/she needs exercise? Drop a ball in your lap? Give you the leash? Destroy toys?
Dakota gets very talkative - more than usual and it drives me nuts. I usually give in just to shut her up.
Neiko pushes toys at me endlessly - frisbee, squeeky toys, stuffies, tennis balls, and so on.
