Haha! Levi likes to "help" me put on his harness, sweaters, jackets, etc. It's too cute when he lifts his little paws. I always put his right paw through first, so after we get his head through, he starts lifting his right paw. I'm waiting for him to start dressing himself on cold mornings.
The funniest "first" would be the first time I saw Levi pick up his harness with his mouth and bring it to me. Of course I took the little man on a long walk after that! That happened over the summer, and it's only happened a couple of other times, but it makes me laugh every single time!
