I have a 4 3/4 month old Leonberger and she already weighs about 40 pounds maybe even a bit bigger, can anyone give me an estimate to how big she will be as an adult? P.S. She is a mix of a St.Bernard, Newfoundlander, and Great Pyrenees.

Leonbergers usually mature around 75-110lbs and 26-32in tall. Sometimes they can be even larger and wih her mix it is possible.
