In two more days the puppies will be four weeks old. and this coincides with Christmas Eve so this week is momentous. Within any given day, the changes in their ability and agility changes. For instance tonight, we had mega kissing and mega nipping. The boys and girls wanted human touch and reveled in this process. There was no growling from Daddy Zack's gate or from Mom Zoies's; just sniffing and licking. So we'll see?.
