4 month old female gsd weight

Question
Hi,
I just have a quick question. I have a female gsd. Her father came from a german blood line but her mother was Amercan. I got her when she was 10 weeks old. I have noticed that she has gained 10 pounds for every month she has lived. She is currently 4 months old and weighs 45.6 lbs. I was told she was the biggest female of the litter. Is this normal growth for a gsd? Or is she going to be bigger than most females? Thank you in advance. Oh and she doesn't look fat at all. She acually looks kind of skinny.

Joe

Answer
It is hard to say.  Some of how big a dog gets depends on how long it keeps growing.  At 4 months, some take a growth spurt, while others level off.  I would expect her to be about the same size as her parents.  

it is quite common for young German Shepherds to be on the thin side.  Some refuse to eat enough to keep their ribs from showing.
