I have never seen any miniature Labs. You have to have a good sized dog for a working dog. My wife's first Lab weighed 54 pounds and it was too small. Her new one weighs 72 and is a perfect size. The owner and dog are matched by personalities and how well they walk together, the harness has to feel right.
Most Labs I have seen are in the 60-80 pound range but I have seen a couple of huge brutes over 100 pounds.
