Book excerpt: The Belgian Shepherd Dog is unique in the world of pedigree dogs, because of the diversity within the breed. There are four very distinct types: the Tervueren, with his profuse double coat, the short-coated Malinois, the glamourous, long-coated Groenendael and the wire-haired Laekenois. Originally bred as a working dog, the Belgian Shepherd has retained much of his working ability, and is used throughout the world as a search and rescue dog, an assistance dog, and as a highly successful police dog where the breed's talents are put to many different uses. The Belgian Shepherd has made his mark in the show ring, but, more importantly, the breed has become highly valued as a loyal and loving family companion. In this highly comprehensive book of the breed, the author traces the origins of the Belgian Shepherd Dog, from the first identified sheepdogs of the late 19th century through to the hard-working, faithful companions and impressive show dogs that we know today.
