They do sleep a lot. Do not disturb their sleep, they need it. I thought something was wrong with my dog because she'd play for 10 minutes and just pass out sleeping for like 3 hours. It was weird but I learned to just let her sleep while I did my thing. Trust me, enjoy your time while your baby sleeps. It's the only time you can do some of your things at home...haha...any pictures of your new pup?
