I'm no trainer, but I guess I can speak of my experience...After a few weekends-a-month of some test runs I used to leave Blue home alone when she was only 7 months and she would just take it as down time and sleep mostly. I would walk her at 8am, noon or 1pm, and evening, it worked out great! BUT if I didn't come home exactly at 5:30pm (traffic in N. VA is so unpredictable) she would tear up all my old college textbooks. So now that I've gotten better furniture, she's crated everyday and I think its alot less stressful for both of us.
