I have an Old Style German Shepherd male (German lines obviously). His mother about 95 lbs and his dad is 125 lbs. He is 18 weeks today, 48.2 lbs and 22 inches at shoulder (withers).
I'll keep posting updates but he's expected to hit at least 100 lbs by 1 yr.

I have GS puppy that is by: Anonymous
15 weeks old and weighs 45 pounds. His dad weighed 84 pounds at 12 months old and 27" at the shoulder, was a little thin for my liking.
We call King Board Patrol, his feet are huge and seems very tall for 15 weeks (20.5" at the shoulder). Your pup seems to be very similar in size, would guess he will go 90 pounds minimum at maturity.
