Any post of mine can be taken way off cousre especially with talk of dogs especially GSD's
.
Just remember with your girl that size and weight means nothing. By the standard a female should be no smaller than 22" and no taller than 24" at the shoulder. My within that range females usually weigh about 60 - 65 lbs. Males should be 24" to 26". You should also be able to see the last rib or clearly feel it. Your girl will not probably end up being a runt.
These people that say "my Shepherd weighed 120 lbs" or that brag that "theirs get to 30" and weigh over 100 lbs" are just wrong. 
It is unhealthy for this breed to be too big..................off my soap box, sorry.
Every other Sunday training is 10 miles up the road and the other Sunday (today) it is 50 miles. The agility type stuff is part of Schutzhund and we start them young. Also scent tracking is another part which I haven't started yet and should have.
Gotta go make some treats for today's training. Oops ...also get dad a card and drop it off......
