Cavalier King Charles spaniel is a breed of dog developed in England in the 1920’s. It was named after King Charles II of England. The dog resembles its close relative, the English toy spaniel, but it has a longer nose. Its silky coat can be red; black and tan; chestnut and white; or black, tan, and white. Longer fringes of hair grow on the ears, chest, legs, tail, and feet. The dog weighs 13 to 18 pounds (6 to 8 kilograms) and stands about 1 foot (30 centimeters) high. It makes a gentle, affectionate pet. However, most Cavalier King Charles spaniels develop heart disease, and many develop eye, ear, skin, and joint problems. Breeding the dog is banned in Norway because the breed’s poor health violates Norwegian animal welfare law.
