My sweet girl is 1 yr old and almost weighs 11 lbs. Her mom was 5 lbs and her dad was only 3 lbs. I am happy she is larger because I don't worry about her as much. My pup also came with those papers and I know she is a pure breed but it doesn't matter to me, I didn't even send them in because I am not going to show her, only spoil and love her
