Silver Labs, real or "designer"?

I was interested to hear about others seeing hyper huge labs as I have been noticing that too lately. I saw the most huge chocolate lab, it was bigger than a Weim and very beefy, he was absolutely uncontrollable, extremely hyper and I thought it was a young dog until the owner told me it was 5! I have seen more and more of these type of labs, all chocolate in Norfolk.

yep there are alot of LARGE HYPER chocolate labs around here lately too.
