  So true.  My guys parents are like 4lbs for their Mother, and just a little more for the Male.  And, ALL of their pups are whoppers.  

It's amazing that the Mother can keep up with nursing.  I remember my Breeder quite some years ago, "warning" me about it, and saying that She hadn't had one that matured out under 8 pounds yet.
