How much sleep do three month old puppies need. My puppy has been sleep a lot lately. He sleeps all night and plays for about three hours after getting up, eating and the other daily things done. He seems to sleep most of the afternoon anymore.

Puppies sleep a lot, it's normal. They will play for a few hours solidly and then crash hard for a few hours then be back up playing again.
Sometimes it's hard to tell when a puppy is unwell because of their sleep habits. Usually disinterest in food, sleeping in strange places (under beds or in boxes) are signs to look out for.
