It of course varies from week to week, but my dogs get a few (like 5 or so) short walks a day to go to the bathroom and sniff around (we don't have a fenced yard, so they need walks to go to the bathroom), then at least once but preferably twice during the work week we take them out to the dog bar or the dog park for an hour of running and playing. On the weekend, they get out of the house for at least an hour both days to go on a hike and/or the dog park (and of course they still get their short walks). I also try to do 5 minute training sessions for each of them at least once a day. Every single day, they play inside with each other. We have a few areas of the house with a good amount of space for them to zoomie and wrestle with each other.
