We don't really have a specific routine, per say. But at least two nights a week we go to my dads house where there's a fenced in yard and other dogs, and he runs a lot. He likes to chase me on the four wheeler, lol (on the other side of the fence) and run at top speed. He does that for about 30 minutes twice a day usually when we're over visiting.
We do agility currently once a week. We try to get outside and do at least 15-20 mins of fetch/frisbee almost every day, weather permitting. Some nights we'll play fetch inside down the long hallway.
At least once or twice a week, we'll do a 5 mile walk in a local neighborhood circle. Otherwise, we'll do shorter walks.
Oh and in the summer he swims in the inground pool, a lot.
