Low-energy puppy

Hi all,

My Weim pup is just shy of 4 months old. He's been a dream, but he's not exhibiting the infamous "high-energy" Weimaraner behavior. He eats well, is very, very food motivated, and has good poops. He's playful, but enjoys cuddling the most. I have wondered if he's bored, but he's not destructive or zooming around.

Is it possible that I could have a low-energy dog or will things change as he gets older?
