English Toy Spaniels are predisposed to mitral valve disease, similar to their close Cavalier relatives, making regular cardiac screening worthwhile. The breed's flatter face also brings some brachycephalic-related breathing sensitivity, and patellar luxation occurs as it does in many small breeds.
Small, measured portions of a quality small-breed diet; watch weight closely given the breed's brachycephalic tendencies and heart disease risk.
The silky coat needs regular brushing to prevent matting, particularly around the ears and feathering.
Gentle and eager to please, English Toy Spaniels train well with positive reinforcement and do best with moderate, low-intensity exercise given their flatter-faced build.
The English Toy Spaniel shares deep ancestry with the Cavalier King Charles Spaniel — both descend from the same small toy spaniels favored by British nobility for centuries — but the English Toy Spaniel was bred toward a flatter face and more domed skull, diverging from the longer-nosed type that later became the Cavalier. Also known as the King Charles Spaniel in its native England, the breed has one of the longest royal associations of any toy dog.
The AKC recognizes four color varieties within the single breed (Blenheim, Prince Charles, King Charles, and Ruby), each with a dedicated following, though all share the same gentle, affectionate toy-spaniel temperament.
