English tend to be more blocky, and shorter though my first lab had english lines and he wasn't short. In europe they have to have field certs to go with their show stuff, not so much here. My new pup is a hunting line, going to be tall and muscular. At 6 months he's just over 60 lbs, fast, lean, and can run forever. Doesn't have a blocky head. The photo is of him at 3 months.
I weighed him this morning, 6 1/2 months old and 68 lbs, he's going to be a beast. Already hard to tire him out, five miles doesn't do it, maybe if I ran him the whole time. Fast, smart and headstrong, he's going to be a great dog.
