Belgian Shepherd is one breed with four coat varieties: the long black Groenendael, the long fawn Tervuren, the short fawn Malinois and the wiry Laekenois. The American Kennel Club registers them separately and calls the Groenendael the Belgian Sheepdog. Many dogs labeled Belgian Shepherd turn out to be Malinois or Malinois mixes, so it helps to know which coat type you're looking at.
Belgians were developed for herding and later became police, military and sport dogs. They're intelligent, watchful and devoted, and most need hard daily exercise and structured training. In Charleston the coat matters: long-coated varieties shed heavily and feel the humid heat, while a short-coated Malinois type has less hair but no less drive. Dogs vary, so spend time with the dog before deciding.
