Agree with others...lots of playing and exercise. Your baby is still very young and is going to play alot. Some grow out of it and some don't. I have two at home that play all day long and my other girl is just a diva. She's content with laying around and doing nothing. My vet recommend that she does more because she's gaining weight so I have to get her to play. It just depends on their personality. To be honest although my guys are older I would never give them anything to calm them down. I actually love to see them run and play.
Maybe try doggie dates or find a brother or sister for your baby
