I second what a few have said, get a good leash, and walk him regularly, aside from his "play" exercise. If you don't teach him to "walk" with you when he's young, you'll regret it. Also, if he will be an inside dog, don't give him table/people food. You'll want to. Try to fight that urge. If not, you'll end up with a 5 year old dog that will sit and beg anytime he sees someone with food. Extra annoying when you have guests or children over. Some breeds are worse than others about this, but it's better to just let them eat their food and you eat yours.
Good luck. Be patient. Dogs are fun, and emotionally very rewarding. You'll experience a love you never knew was possible. There is just great bond you can have with a dog. They love unconditionally. But at the same time, there will be days you will get frustrated to (or maybe beyond) your breaking point. Your dog will likely make you very angry at some point. Try to just walk away, cool off, and then deal with what issues may have caused this (Unless there is an immediate safety issue, of course). Don't reprimand out of anger.
Enjoy... you have an amazing future ahead of you with that cute little pup!![]()
