Jack, my Border Collie, is 'Mr. Energy'. When I'm sitting on the couch, he NEEDS me to throw a toy across the room. He brings back the toy and drops it in my lap. This will go on for hours and hours, which is why I never sit on the couch for long. If I try to ignore him, he puts his chin on my knee and hums.
Jack sleeps on my bed. When he is taking more than his fair share of the space, I nudge him over with my knee. This sets off a long 'talking' spree (mumble, mumble, mumble), a turn-around-three-times maneuver, and a final big plop right next to my side, with his chin on my chest. Then he looks at me with those big brown eyes and smiles.
Oh, and he can't go outside in the morning, when I leave for work, without his 'cookies' (Milk Bones).
