I currently have 3 puppies in the house. 2 at 7 weeks and 1 at 9 weeks. All three go to sleep at about 630 or 7 pm. and sleep until about 3 a.m. They want food and a little play time and then they go right back to sleep until morning. I'm up about 15-20 mins and then it's back to bed. Of course all puppies are different, but thought I would let you know about these 3 little guys.
