Hi JaTa
That would depend on the individual puppy. Some don't take to the leash very well, and need a little time to get used to it. Others want to run and jump, and basically go off in all directions. It'll probably take a little time for him to 'walk' properly. They usually let you know when they've had enough. They'll either refuse to walk and look up at you to be picked up, or lie down. My advice would be to start slow and gradually increase the length of the walks.
