All day Thursday, Bruno did not stop...Even after Hiking.....Friday, Bob took him for two more Hikes and that did it...After attempting to break into the Tent, that was zipped up, Bob let him go in the Tent to go to Bed...He was literally nodding off with his head up...When it was time to take the Tent down and go, Bruno wouldn't have it, so Bob dismantled the Tent around him...I think Bob said Bruno ended up sleeping all the way home...Kudos to Bob for managing to wear out a Lab....
