One of the four types of Belgian sheepherding dogs, the Belgian Malinois is an alert, high-energy breed, popular as both a police and military working dog. Although sometimes mistaken for the German Shepherd Dog, the Malinois is more elegant in build and lighter-boned, but does not lack for strength, agility or herding ability. Active participants in conformation, obedience, schutzhund, herding, sledding, and tracking, the breed ranges in color from rich fawn to mahogany, with black tips on the hairs and a black mask and ears. Intelligent and trainable, the Belgian Malinois possesses a strong desire to work and is happiest with regular activity and a job to do. A relatively easy keeper due to their medium size and short coat, this confident breed loves their families, but may be somewhat reserved with strangers. They are naturally protective of their owners without being overly aggressive.
