Good looking, good sized pup. Everything that you've said seems completely normal, as far as trying to get him to come etc, it's never too early to start clicker training. Even if you just click normal behaviors like everytime he sits, lays, or comes to you on his own. I have a 6 month old blackie myself and he's pretty well behaved but I definitely wish I'd have started clicker training earlier. Just a thought, good luck!
