I have a German Shepherd who is 3 1/2 mth, I want to know by looking at his pictures how he looks for his age?

He looks just like my German Shepherd did when he was a puppy. Although, my German Shepherd lost alot of the black in his face and it turned to tan as he got older. He was almost 6months before his ears stuck up completely ---his ears will go up, don't worry. He looks pure-bred to me, congrats, they're wonderful dogs! Google them, you'll learn so much neat info on them.
