Cavalier King Charles Spaniel Puppies: 10 Must-Knows Before Buying

The Cavalier King Charles Spaniel is one of the most beloved companion breeds in the United States, renowned for its silky coat, expressive eyes, and extraordinarily gentle, adaptable temperament. Named after King Charles II of England, who was famously devoted to the breed, Cavaliers have served as companion dogs to royalty and nobility for centuries before becoming one of the most popular family pets across the globe.

Cavaliers are small to medium-sized dogs, typically weighing between 12 and 18 pounds, with a graceful, well-balanced build and a flowing, silky coat that comes in four recognized colors: Blenheim (chestnut and white), tricolor (black, white, and tan), black and tan, and ruby (solid red). Their large, round eyes and soft expression give them an immediately appealing, gentle appearance that matches their equally gentle personality. The coat requires regular brushing to prevent tangling and professional grooming on a periodic basis.

Temperamentally, Cavaliers are among the most people-oriented breeds in existence, thriving on close human contact and adapting beautifully to a wide range of households, from active families to quiet senior companionship. They are generally excellent with children, other dogs, and even cats. Unfortunately, the breed carries a significant burden of heritable health problems. Mitral valve disease (MVD) is present in the vast majority of Cavaliers by middle age, often leading to heart failure. Syringomyelia, a painful neurological condition caused by the skull being too small for the brain, affects a substantial proportion of the breed. Responsible breeding with rigorous health testing for both conditions is essential, and prospective owners should work exclusively with breeders who follow the Cavalier Health protocol.
