Seriously I've had labs for about 40 years now (raised them for about 35). I had all colors. My wife is fond of the yellows and I prefer the chocolates and blacks. In fact right now as I type this I have a yellow female lying at my feet on my right and a black female lying right behind the computer chair!
I had a gorgeous chocolate female that was the best hunting dog I ever owned for upland birds and waterfowl. She wasn't big but she was one hell of a dog. And I swear she could read my mind! Easiest dog to train I ever had. Hand, whistle and voice commands were obeyed immediately. I wish my wife would listen a tenth of how she did!!!
