Opie, German Shepherd Mix, wondering how much shepherd you think he has?

I adopted Opie from the SPCA and he is lab/shep, with a little Chow (spotted tongue). Was curious how much shepherd you think he will be? His coat is almost all gold with black on the tail and muzzle. I can see fur growing in on his back/ears/neck that is black. He has perky ears already but was told sheps have flappy ears when they are little. I wanted a german shepherd but couldn't afford to get a purebred or whatnot. Just wanted to know your thoughts! He was 9 lbs at 8 weeks (when I got him) and 11 pounds at 9 weeks.
