When I came home after being gone for a week, I found that Cooper had a growth spurt!  I almost didn’t recognize him!  Even after the 4 miles and 135 lunges that we did this morning, he still wasn’t tired.  I’m not sure how I’m going to keep up with him.  Today he goes to his puppy class, but he missed a week and he had a week of no practice.  I’m pretty sure he’s going to have to take a repeater class.  It’s a good thing he’s so cute!!
