Although your little lady is to small to have babies I would like to clear up a little about your male being 6 and 1/2 pounds.....is he over weight? is he heavied boned?..are his genetics from larger adults and grandparents? there are alot of questions here....because even thou he is 6 and 1/2 pounds does NOT mean he will have large puppies, I have seen 7 pound males throw SMALL puppies and 3 pound males throw LARGE puppies.....it is the genetics of the parents of you female and male and grandparents that you need to check out....just thought this might help!
