We exercise Peggy conservatively. I don't want her turning into a marathon runner or adrenaline junkie. She's almost 9 months old and on an average day gets a 20-30 minute frisbee/flirt pole/fetch session in the backyard, as well as a 15-minute stroll or two around the neighbourhood. This is in addition to multiple short indoor training sessions (literally about a minute each), some low-key indoor play, half a dozen outdoor on-leash sniff & potty breaks, and lots of just "hanging out" together: She accompanies me while I do laundry, make the bed, cook dinner, etc.
Once a week we attend a one-hour training class, which completely exhausts her. We also do lots of homemade puzzles and games. In general, I find she gets the most worn out when she uses her brain and nose. Letting her sniff her way around the outside of our local Walmart, for example, is a great way to tire her out while also working on her manners and exposing her to a variety of sights and sounds. Same goes for strolls inside Petco.
So I guess you could say I focus on quality not quantity, at least for now. She might demand more as she gets older.
