Profile & Natural History
Toy spaniels appear in Dutch and Stuart portraits from the 1500s; American breeders in the 1920s recreated the longer-muzzled type seen in old paintings and the modern Cavalier was born. It has since become one of the most popular companion dogs in the world — for good reason and with one heavy caveat.
Temperament. Cavaliers are the peace treaty of the dog world: sweet with children, cats, strangers, and grandmothers. They retain sporting instincts — chasing birds and squirrels with real joy — and are highly trainable with soft methods. Separation distress is the breed's behavioral weak point; they want their people nearby.
Care. The silky coat needs brushing several times weekly; ears need weekly attention. Exercise is real: a solid daily walk plus play keeps Cavaliers fit and content. The caveat is health — mitral valve disease affects a majority of the breed by age ten, and syringomyelia occurs in some lines. Choosing a breeder who heart- and MRI-screens breeding stock is not optional; it is the single most important decision in Cavalier ownership.
Fits: families, seniors, therapy work, first-time owners. Thinks twice: buyers who won't vet breeder health testing — and households wanting a dog with longevity certainty.
