What Is the Difference Between Cavalier and King Charles?
Before comparing temperaments, let's understand what makes these two breeds different.
Two Distinct Breeds
Separate breeds: The King Charles Spaniel and Cavalier King Charles Spaniel are recognized as two completely different breeds by kennel clubs worldwide.
Different names: King Charles Spaniel is also called the English Toy Spaniel. Cavalier King Charles Spaniel always uses the full name.
Common confusion: Many people think they're the same breed or just different sizes. They're not—they're distinct breeds.
Historical Background
Original toy spaniels: Small companion spaniels were popular in 16th-17th century England, appearing in paintings with royalty.
King Charles II: King Charles II (1630-1685) loved these small spaniels. They became associated with his name.
Breed changes: In the 1800s-early 1900s, breeders changed the original spaniels. They bred for shorter noses and domed skulls. These became the King Charles Spaniel (English Toy Spaniel).
Breed recreation: In the 1920s, an American named Roswell Eldridge wanted to restore the original spaniel type with longer noses. He offered prize money at Crufts dog show for dogs resembling old paintings. This led to the recreation of the original type, named "Cavalier" King Charles Spaniel.
Modern breeds: Today, the King Charles Spaniel represents the modified 1800s version. The Cavalier King Charles Spaniel represents the recreated original type.
Physical Differences
Size: Cavaliers are larger, 13-18 pounds. King Charles Spaniels are smaller, 8-14 pounds.
Head shape: Cavaliers have longer noses and flatter skulls. King Charles Spaniels have very short noses (brachycephalic) and domed skulls.
Eyes: Cavaliers have large, round eyes. King Charles Spaniels have even larger eyes that are more prominent and forward-facing.
Face: Cavaliers have a gentler, more moderate facial structure. King Charles Spaniels have a flatter face similar to Pugs.
Ears: Both have long, feathered ears, but they sit differently on the head due to different skull shapes.
These physical differences affect health and, to some extent, temperament.
