Hi Ryan
I posted a similar thread a while ago (see overweight dogs) as I too was really worried about the weight of my GSD. I had a few people comment that he was thin and like you had taken him to the vet to have him checked out.
Pam (Wildmoor) posted a really good reply, which made me feel so much better. She basically said not to worry that he will naturally fill out as he gets older and that he's the right weight for his age. Diesel is the same weight as your GSD and he's going to be 3 in December so I don't think you have anything to worry about.
I think so many people are used to seeing overweight dogs that a fit and healthy dog is regarded as thin!
Your GSD looks very much like my Diesel
