Update! ... we went to the vet today and got a clean bill of health... he is 10 weeks tomorrow and weighs a whopping 3.3lbs... so I know he will be a bit on the 7lb side I think? Is that right? it doesnt matter I just want to know what to expect... I am glad I got him b/c my daughter is all over him... he will be nice and sturdy for her to play with...
