Around what age do they start to frap? Olive is 9 weeks old, and has yet to go nuts running around. We keep her in the family room and kitchen area (open kitchen with an island seperating the two rooms... pretty large area), and take her outside only to go potty right now. Do they need more exercise to get the urge to frap? we play with her a lot with her rope and chew toys. Just curious! (We haven't been successful in getting her to go for a walk yet.)
