my little billie is very affectionate i havent seen her 'alpha' side but i think it will come out when i add a new pup to the family. i want to add a girl pup but lots of posts throughout this site make me think a boy would be a better match. I am hoping when i go to meet the new puppies it wil be clear to me then which one is coming home with us!
i have this link bookmarked for when our little one joins us
