Size and Build
The King Charles Spaniel is a small, compact breed with males and females standing between 23 to 28 cm at the withers and weighing between 3.6 to 6.4 kg. Their body is elegant yet sturdy, featuring a distinctive domed head which lends them their noble appearance. The short muzzle is complemented by a broad, upturned black nose and a well-pronounced stop. Their neck is medium length and slightly arched, supporting a proud carriage. The forequarters are well-developed, with short, straight legs and well-laid-back shoulders. The chest is deep and broad while the back is level and short. Hindquarters show strong muscle tone and straight legs. Feet are compact, well padded, and feathered, resembling a cat’s paw.
Coat and Colours
The coat is long, fine, silky, and either straight or lightly waved, never curly. The feathering on ears, legs, and tail enhances their delicate appearance. The Kennel Club recognises four primary registered colour patterns:
- Black & Tan: A glossy black coat with rich mahogany markings on the muzzle, legs, chest, ear linings, under tail, and spots above the eyes.
- Blenheim: A pearly white base with chestnut markings distributed evenly, including the signature clear wide blaze and "skull spot" on the crown.
- Ruby: A solid, deep chestnut red throughout the coat.
- Tricolour: Pearly white base with balanced black patches and clearly defined tan points on the cheeks, ears, under tail, and above the eyes, with a broad white blaze.
Distinctive Features
The breed's large, dark eyes set wide apart and dome-shaped head contribute to a profoundly gentle expression prized by judges in the show ring. The ears are set low, long, and heavily feathered, lying close against the cheeks. The tail, often naturally bobbed or feathered, is carried straight but never curled over the back. Their gait is effortless, smooth, and reflects strong hindquarter propulsion.
Gender Differences
Males may be slightly larger and heavier than females within the same size range, but temperament does not vary significantly between genders. Both sexes are affectionate, sociable, and gentle, with show standards emphasising well-balanced proportions rather than size differences.
