Boyd is 17 weeks old tomorrow and over the past week putting on the leash has turned into a game. He used to sit quietly by the door (which he still does first thing in the morning) but now he treats it like a game. He will go to the door and look at us and then when we approach with the leash he'll adopt puppy play mode - butt in air, tail wagging - and then take off around the kitchen. When we finally get the leash on him and take him out he relieves himself so it's not like he's "faking" it. Why is he doing this?
