Size and Build
The Korthals Griffon is a medium-sized dog, with males typically standing between 55 and 60 cm at the withers and weighing from 29 to 34 kg. Females are slightly smaller, ranging from 50 to 56 cm in height and 25 to 29 kg in weight. They have a strong, muscular build suited to vigorous working, with a deep chest and slightly sprung ribs. The body is compact yet powerful, supported by long, well-angulated shoulders and muscular hindquarters. Their feet are round and tight with well-arched toes, reflecting their agility and endurance in the field.
Coat and Colours
This breed is known for its harsh, wiry coat which is complemented by a finer, dense undercoat that offers protection in harsh weather. The accepted Kennel Club colours include brown and grey, chestnut roan, and steel grey with liver markings. Additional acceptable colours also feature solid liver/brown, liver roan, and patterns involving white and brown patches. Notably, the undercoat always has a brown tint regardless of the outer coat colour. Seasonal shedding occurs, particularly in spring and autumn, which requires increased grooming attention.
Distinctive Features
The Korthals Griffon’s head is distinctive with a large, long but not overly broad shape covered in harsh hair. Their square muzzle aligns parallel with the top of the skull, and their noses are always brown with a slightly convex tip. Pronounced bushy eyebrows give an intelligent and alert expression, enhanced by large, round eyes which may be brown or dark yellow. Medium-sized, flat ears are set level with the eyes and covered in a mixture of short and long hair, complementing the balanced head structure. Their tail is carried horizontally, often with a slight upward tip, and is abundantly coated with coarse hair without feathering.
Gender Differences
Males of the breed tend to be more robust and slightly larger than females, both in height and weight. Temperamentally, males can be a bit more assertive, while females often display a gentler disposition, though both require consistent training to optimise their hunting and companion qualities. Show rings prefer dogs that closely adhere to the breed standard in structure and coat quality, highlighting proportion, coat texture, and expression as important judging criteria.
