To be honest I can't remember what my girl weighed throughout but I know when we brought her home at 8 1/2 weeks she was 9 lbs. She now full grown is around 60-62 lbs. She is however a big girl but her father is 72 lbs. and her mom is around 60 as well so she is from bigger lines. So I would say your's is small but then again I have a very large girl. Our boy who is a rescue and on the slim side is 50 lbs. Both are within healthy weight for their structure. Our girl though is a show girl from show lines.
