Maybe the breeder was swamped and didn't send the papers in on time to have them ready for the pick up? For my litter I faxed everything over and they had puppy papers within about 2-3 wks from my fax date as they were a bit backed up. If you have any questions ask the breeder for clarification and if you want to see the parents as to set up a meeting?
