Sully gets walks (even if only on the treadmill) almost every day of the week but not ALWAYS every day.....so I voted a few days a week.
We play chase around the house CONSTANTLY when we're home and almost every day he gets to go outside and have "doggie time" as we call it with all of our neighborhood dogs. (We have our own dog park at our condo community, it rocks!) While he's out there playing with his friends he gets a LOT of running in there!
