Labs, hands down. They love kids, they love you, they're unbelievably loyal, they're big enough to scare the crap out of someone coming close to your house in the middle of the night (had it happen). The English Lab, white, black, or, brown, are smaller but more stocky, but, sweet and loving. The Eastern US Lab gets to be about 75 pounds, give or take 20 pounds depending on breeding. Western Labs are HUGE. I wouldn't want one of those simply because they can get up to 130 pounds. All in all, they're sweet, sweet dogs. My grand kids ride mine, Murphy, and he just strolls along letting them sit on his back. They also lay on top of him and he never moves. He seems to enjoy it as much as they do.
