Cavalier King Charles Spaniel
About the Breed
The Cavalier King Charles Spaniel is a small companion breed known for its affectionate personality, gentle expression, and adaptable temperament. Cavaliers are widely loved for their friendly nature and ability to fit comfortably into many different lifestyles, from active families to quieter companion homes.
The breed is especially people-oriented and tends to thrive when included closely in family life. Cavaliers are known for being affectionate lap dogs while still retaining some of the sporting spaniel traits seen in their history, including playfulness and enjoyment of outdoor activity.
Because of their gentle temperament and social personality, Cavaliers are often considered excellent companions for families, seniors, and first-time dog owners.
History
The Cavalier King Charles Spaniel traces back to toy spaniels popular among European nobility, especially in England. The breed became strongly associated with King Charles II, who was famously devoted to these small companion spaniels.
Over time, breeders worked to recreate the longer-muzzled toy spaniel seen in historic paintings, eventually developing the modern Cavalier King Charles Spaniel recognized today. The breed combines companion-dog affection with the gentle sporting temperament of small spaniels.

Cavaliers generally stand about 12–13 inches at the shoulder.
Weight

Overall Health
Cavalier King Charles Spaniels are affectionate and adaptable companions, but the breed is known for several important inherited health concerns that responsible breeders work carefully to monitor. Heart disease, neurologic disease, eye disorders, and orthopedic concerns are among the most significant issues within the breed.
Mitral valve disease is especially common in Cavaliers and remains one of the most discussed long-term health concerns. Because of this, careful breeder selection and ongoing cardiac monitoring are extremely important.
Maintaining healthy weight, routine veterinary care, and responsible breeding practices can help support long-term quality of life within the breed.

Cardiac evaluation by a veterinary cardiologist
Eye examination by a veterinary ophthalmologist
