I think this is a fundamentally flawed article. Anything that cites Ceasar Millan as much this one does can't be reliable. Honestly, it completely depends on the individual dog. I don't think you can chose a "family friendly" dog based on the breed, especially since most breeds that are considered to be good with children are from some of the most popular types in the US- meaning you get a huge variation in temperament, activity level, and prey drive.
I agree with their inclusion of dogs such as the Newfoundland, BMD, Bichon Frise, Bull Terrier, and Labradoodle. However, I don't think the GSD or Labrador Retriever should be included. While a GSD can be a great family dog, they also need an increased amount of exercise and training that may not be able to be allotted by owners with children. I wouldn't rule them out, but I also wouldn't recommend them. Similarly, labs have the reputation of being an all-around, easy dog, but I don't agree with that portrait either. The adult labs that I have worked at have either filled the stereotype or been incredibly reactive, protective, and not suitable for the average household. One in particular, who's owner I helped teach some basic obedience work, has run multiple yard workers/delivery people off the property, and must be walked in a muzzle because he would lunge at any man who approached within a certain radius. In addition, labrador puppies are very high energy and nippy. They are stirred to play by small, active children, but take longer to understand the rules of interaction with people- especially bite inhibition.
