Our 7 month old male lab has switched his days and nights. We take him walking twice a day and play regularly with him in the yard. But when we are not doing this, he sleeps (on the floor right next to me). Then, at night, after 2-3 hours of sleep, he's up and barking for someone to play. He just started doing this in the last 2 -3 weeks. Before that he slept 7-8 hours in our bedroom in a crate. What can we do to solve this?
