Hello I have decided to get this wonderful dog. I'm so excited. I have just one question. The breeder is asking if I could pick up the puppy 4 days before 8 weeks old. I was under impression puppies should not be picked up between 8-12 weeks. Is this unusual? Should I be concerned? Also what is the average weight for a puppy this age. Her father weighs 140 lbs, her mother weighs 110 lbs.
