American Kennel Club (AKC)
General Appearance: The first impression of the Belgian Sheepdog is that of a well-balanced, square dog, elegant in appearance with an exceedingly proud carriage of the head and neck. He is a strong, agile, well muscled animal, alert and full of life. His whole conformation gives the impression of depth and solidity without bulkiness.
Size, Proportion, Substance: Males 24-26 inches in height and females 22-24 inches, measured at the withers. The length, measured from point of breastbone to point of rump, should equal the height. Bitches may be slightly longer. Bone structure is moderately heavy in proportion to his size so that he is well balanced throughout and neither spindly or leggy nor cumbersome and bulky.
Head: Clean-cut and strong, overall size should be in proportion to the body. Expression indicates alertness, attention and readiness for activity. Should reflect the dog's intelligent, questioning nature. Eyes brown, preferably dark brown. Medium size, slightly almond shaped, not protruding. Eye rims black. Ears triangular in shape, stiff, erect, and in proportion to the head in size. Set high, the base of the ear should not come below the center of the eye. Skull flattened rather than rounded. The width approximately the same as the length but no wider. Stop moderate. Muzzle moderately pointed, avoiding any tendency to snipiness, and approximately equal in length to that of the topskull. Nose black without spots or discolored areas. Lips tight and black, with no pink showing on the outside.
Coat: The guard hairs of the coat must be long, well-fitting, straight and abundant. They should not be silky or wiry. The texture should be a medium harshness. The undercoat should be extremely dense, commensurate with climatic conditions. Color: Black. May have small to moderate patch of white on forechest, between pads of feet, on tips of hind toes. White or gray frosting on muzzle. Disqualification: Any color other than black, except for white in specified areas.
Fédération Cynologique Internationale (FCI)
General Appearance: The Belgian Shepherd Dog is a harmoniously proportioned, medium-sized dog that combines elegance and power. He is of medium length, wide, deep and solid without being heavy. The musculature is dry and strong. The whole conformation gives an impression of elegant robustness proper to an ardent and resistant worker.
Important Proportions: The Belgian Shepherd Dog is square; the length of the body from the point of the shoulder to the point of the buttock is equal to the height at the withers. The chest is let down to the elbows. The length of the muzzle is equal to or slightly less than half the length of the head.
Behavior and Temperament: The Belgian Shepherd Dog is vigilant and attentive. Of unshakeable loyalty to his handler, he is also an excellent guardian of property. Without hesitation he defends his master and property if the situation requires. All his characteristics make him eminently sociable for the work for which he is intended.
Coat (Groenendael variety): In all parts of the body the hair is long and straight, abundant, of good texture, forming with the thick undercoat an excellent protective covering. It is particularly long around the opening of the ear, on the upper part of the forearm, especially at the back of the legs where it forms fringes, and on the tail where it forms a plume. On the head the hair is shorter, and on the lower part of the legs it is short and tight.
United Kennel Club (UKC)
The UKC recognizes the Belgian Shepherd Dog as four distinct varieties based on coat type and color, including the Groenendael variety which is characterized by its long black coat. The standard emphasizes the breed's working ability, temperament, and proper proportion while maintaining consistency with international standards.
General Appearance: The Belgian Shepherd Dog presents a harmonious blend of power and elegance. Medium-sized and well-proportioned, the breed displays remarkable versatility as both working dog and family companion. The overall impression should be one of balanced athleticism with noble bearing.
Character: The Belgian Shepherd Dog is highly intelligent, alert, and responsive. The breed displays natural protective instincts balanced with loyalty and affection toward family. Training should bring out the breed's natural working ability while maintaining the confident, stable temperament essential for both working and companion roles.
Other Organizations
The Kennel Club (UK) follows FCI standards closely, recognizing all four Belgian Shepherd varieties as a single breed with different coat types. The Canadian Kennel Club aligns with AKC standards while incorporating health testing requirements and emphasizing the importance of proper temperament evaluation.
Many European breed clubs place additional emphasis on working capability testing, requiring dogs to demonstrate herding instinct or other working abilities before receiving full breeding approval. Australian and New Zealand standards focus heavily on correct movement and gait, reflecting the breed's role in covering vast distances in agricultural settings.
International organizations consistently agree on the breed's essential characteristics: the square outline, distinctive head shape, proper coat texture and color, and the balanced temperament that makes the Belgian Groenendael both an effective working dog and devoted family companion. Variations in standards typically relate to minor measurement differences or specific health testing requirements rather than fundamental breed type.
