Belgian dog breeds are well known for their intelligence, athleticism and loyalty. Many are used in a variety of roles, such as police, guard, hunting and military work. The most popular among them are the Belgian Malinois, Belgian Sheepdog and the Belgian Tervuren. All three have a strong and devoted bond with their owners that makes them great family pets. Their coat colors can range from black, brown, grey and white, and they require a lot of exercise and grooming to stay healthy.
