AWWWWWWWWWW!!!
They are so precious, but this is the same thing that happened when I got my puppy! She has GSD coloring but is built like a lab. Her mom was the same way. We had trouble figuring this out, because she was the only pup with the GSD colors, all others where black or white. Look at the body shape, the colors of fur, and quality of fur (i guess thats how u would put it, LOL) then do some web searches, it helped us!

I ABSOULUTELY luv the dark brown 1 with lil boots!!!
