Cavalier King Charles Spaniel: Complete Breed Guide to Temperament, Health, and Care
The Cavalier King Charles Spaniel diverged from the King Charles Spaniel in the 1920s, when breeders sought to recreate the longer-muzzled spaniel type seen in art from the English Civil War era. In 1926, American Roswell Eldridge offered prize money for spaniels of this “old type,” sparking the first Cavalier club in 1928; the Kennel Club formally recognized it as a separate breed on December 5, 1944.

Executive Summary
The Cavalier King Charles Spaniel is highly affectionate, playful, and eager to please, historically bred to keep up with a trotting horse as both lapdog and hunting companion. It regards all strangers as friends, making it a poor guard dog but an excellent therapy and companion animal.
What Owning a Cavalier King Charles Spaniel Involves
| With training & care | Without it |
|---|---|
| Affectionate, patient companion suited to families | Separation anxiety when left alone too often |
| Regular cardiac screening catches mitral valve disease early | Undiagnosed heart disease, a leading breed health concern |
| Awareness of syringomyelia symptoms enables early vet care | Undiagnosed neurological pain from syringomyelia |
| Routine eye and joint checks catch issues early | Undiagnosed luxating patella or eye disorders |
3 Real-World Scenarios
- A family wanting a patient, affectionate companion for children: picks the Cavalier for its documented gentle, eager-to-please temperament, one reason it excels as a therapy dog.
- An owner monitoring heart health as the dog ages: schedules regular cardiac screening, since mitral valve disease is one of the most significant documented health concerns in the breed.
- A prospective owner researching the breed’s real history: learns the modern Cavalier only became a distinct recognized breed in 1944, sparked by a 1926 prize offer for the “old type” spaniel.
2 Cavalier King Charles Spaniel Facts
1. The entire modern Cavalier King Charles Spaniel breed can be traced to a specific historical event: American Roswell Eldridge’s 1926 offer of prize money for spaniels resembling the “old type” seen in historical paintings, which directly led to the first Cavalier breed club in 1928.
2. Syringomyelia, a serious neurological condition affecting the spinal cord, is documented at unusually high rates in the Cavalier compared to most breeds — a direct consequence of the breed’s characteristic skull shape.
