Yes, the little avatar pic is Bear on his first day "home". My last dog's muzzle grew like Pinocchio's nose (without the lies). It was a short stubby as a pup, and elongated as he grew. He went from looking like a black lab, to a floppy-eared GSD with lab fur on his head and ears.
I agree about the scaring us poor parents. The doctors did the same thing to me with my daughter, who, before she turned 4 yrs old, was in the 5th percentile for weight. Now she's nearing the 75th percentile in weight, and 10th percentile in height. Only time can tell.
I was just hoping someone might have a GSD with similar weight stats. No worries if he turns out to be the size of an elephant. Well, on the other hand, maybe I should just go out and buy stocks in the dog food company now.
