Belgian shepherds are medium-sized dogs with a slender build. As their name suggests, they were bred in Belgium, where they were used as herding dogs. Although originally working dogs, they can make great pets, as long as they get sufficient exercise. The American Kennel Clubs recognizes four different types of Belgian shepherd, each named after their area of origin. The main difference between these varieties is their coat type.Tervuren,Groenendael,Malinois and Laekenois.
