Oh another change we are going through is his bark! All of a sudden he has started howling instead of a high pitched yap. It is the funniest thing. My bro&sis-in-law had a alaskan malamute, and he sounds just like their dog did. He does this especially when he thinks someone is coming to the house, or if something's not quite right. It's really cute, but at the same time I am just hating that he is losing his puppyhood all at the same time.
