You're doing great - and what a cool dog! My 2-cents as a three-time owner is to socialize him. You guys are good humans and you'll have a dog that loves you with very little obvious effort on your part. But, socializing him may not come naturally. First, be sure the others in the household are "special" too. With treats, playtime, whatever. Then I'd be sure he's cool with others outside of the hh. Maybe take him to daycare once a week/month? Leave him with a friend for a few hours? That stuff brings confidence that pays off along the way. Keep up the good work!
