I would be wary, no good breeder lets a puppy go before 8 weeks of age.

Did you get a vaccination card with him to prove he has had all his shots?

In saying that though puppies do sleep a lot, they play for half an hour, sleep for 2 hours then get up and play again.
If you are worried just give your vet a call and see if they think you should bring him in.
