Jug Dog Personality

I was confused my Jug Milford is now 1 years old and what was on my mind is it normal for this breed to be more homebody types and not that outgoing at times? I am that way as a person so I figure maybe he is following me? we do walk as well as play and have ''tv time'' so I don't think he is depressed far from it, he is good with other dogs but doesn't go out of his way is more reserved
