Being man’s best friend, a dog definitely makes an excellent family pet, but some breeds are more suitable than others. The single most important quality is the ability to get along with children. A family dog should be easy going and tolerant, but also playful and a good companion. Some people may also want an animal that will discourage would-be intruders — in this case, protectiveness and an imposing appearance might be considered important characteristics. While, with the right training, any specific breed, or mixed breed dogs, can make a wonderful companion.
