When i walk out the door to our apt on the 3rd floor i close the door with the key while i am doing this he is whining like theres a big treat for him downstairs and he cant wait to go get it. when it comes to outside he leads the way as much as i try and keep him next to me he loves to sniff the grass and all that and besides he's a puppy he's curios so i let him what the heck
