Lab Puppies

I’ve considered getting a dog, perhaps a puppy, and even perhaps a lab puppy for my son for his birthday. Lab puppies I’ve heard are the most relaxed laid back puppies there are, and I don’t want some sort of aggressive dog or puppy anywhere near my kids or in my neighborhood. The only issue really is finding a good one from a reputable labrador retriever breeder in my area and picking the color. Not sure if a chocolate will be the best? or perhaps a white, black. or yellow lab?
