I have a black lab pedigree and my mum is obcessed with GSD's so in our house you have to like both breeds. I personally love labs, mine is called Pepsi, she is so smart. I take her obedience training every week and she is the best there. Just to prove to everyone at our club of how clever labs are I took her to a championship show and she qualified for obedience at Crufts in the UK.
So that proves that labs are better than collies.
