Labs are good dogs. Great around kids and a great dispsition.
I have two Labs that are crosses - one is a half and halfer, one is about 1/4 show and the rest field. They both are very easygoing, friendly, and great with kids. And they're decent hunters, in fact my oldest Lab has two siblings that have gone all the way in HRC (to Grand Hunting Retriever Champion).
My middle Lab is 100 percent field bred (with a small admixture of what's called a dual purpose dog - they're getting rare) and she is a loon. She is MUCH better at pure retrieving than my other two, she was born to do 200 yard retrieves and run all over hell's half acre. Very stylish and very very fast - the judges at the hunting tests just love her (so long as she doesn't get overexcited and get completely out of my control - amateur trainer-handler here, she'd do fine with a pro). But even at 3 years old she would run over a small kid and not even know she hit a speed bump. She'd be very sorry afterwards - she's a sweet affectionate girl, but that wouldn't do the squashed kid much good. It's like having a Ferrari in the living room. I call her "Marley to the Third Power". Great dog but not for everybody.
