Hi,
My male who is three now used to hump his toys when he was around 12 weeks old, it went away except for one toy that he humps now if we keep it around for him. He's been nuetered since he was 8 months old and doesn't hump anymore.
Both of my males kick after they pee, and the 12 week old girl puppies both kick after they pee on their pads but not outside yet. We don't have any problems with their behavior.
Maybe he's just trying to make his place with the other girls.
