My Tucker is 5 months old, and yes- I do find he has a lot of energy....but it seems to be in short bursts. He is an early riser, but thankfully the 3am/4 am/5 am's have pretty much stopped, and now he's ok getting up at 6 am, when I normally get up.
But he will play/play/play like crazy first thing in the morning, especially with our one cat, Simba (1.5 years old), and getting him to heel and listen to voice commands on the morning walk is almost impossible. He wants to smell everything, chase bugs, meet everyone- its exhausting! BUT...all this only seems to last the first hour or so of him being up. Then he's calm, hanging out, eating his breakfast, watching my husband and I get ready for work. He goes to his "room" (kennel) no trouble, and we leave.
I come home at lunch (3.5 hours later) and give him lunch, walk him again, and he's the best behaved puppy ever, heels like theres no tomorrow- but will still burst out of that quiet demeanor if there are people/other dogs around, and will be crazy, bouncy again- and then switches it off, and is back to being calm and cool. He is much the same way on his nighttime walk, though I do notice he doesn't behave quite as well as the mid-afternoon walk, perhaps because this is the only walk that my husband accompanies us on?
I would agree with the other poster, every puppy is different, even inside its own breed, I'd classify Tucker as "laid back with short random bursts of energy", and I've heard much the same from friends with Berners.
BTW- your profile pic is cute! Your pups look adorable.
