Congrats on your new puppy. My pup is now 5 months old, so I know what you're talking about! To help occupy Isen, I bought a flirt pole off of Amazon.com to help exercise Isen. He loved it! As they get older, their energy level increases lol, not decreases. A tired puppy is a good puppy lol. For potty training, I took Isen out every 20 minutes, whether he looked like he needed to go or not. Also right after he drank water. They are smart and pick up quickly where they should use the bathroom. Good luck and enjoy your puppy!
