it looks like he's only 4 months old? I guess he'll be what he'll be.
If he's ok medically, well maybe as he ages he'll pick up the pace?)
I have had 1 couch potatoe, but then again, it was my husbands dog so they were a perfect match

Ever since I had my 6mo, he's for the most part totally fine and mellow in the house, and even if we skip walks or exercise in general. It's sort of like he realizes the house isn't anywhere to get his energy out, and I've reinforced that... I take him out at least once in the morning and or evening to do what ever. As long as he is out once every 24 hours, he does fine and doesn't get hyper.
Though, I do always substitute obedience in place of a skipped session.
He makes a lot of people jealous, it makes you realize that low energy is a really good thing. He gets it going when it matters.
What Carmspack said. Does he like to go for walks or chase a ball, or do these things not interest him? Is he eating well? Growing well? How is his attitude... does he seem friendly and happy, just mellow? Or does he seem indifferent to people and things around him? Does he ever get scared? When he moves, does he move in a loose, relaxed fashion, or does he walk stiffly?
