The Cavalier King Charles Spaniel belongs to the ninth group of this classification: pleasure and companion dogs.

The Cavalier King Charles Spaniel joins more precisely the seventh category of this group dedicated to English Spaniels.

The Cavalier King Charles breed has existed since the 15th century; its history is both recent and ancient. Indeed, it was in 1926 that an American amateur noted the fact that the current King Charles was different from the Spaniel that was represented on the paintings of the past. English breeders then tried to recreate the ancient Toy Spaniel, the favorite of the kings and princes of England. The first strains of Cavalier King Charles came from crosses between the King Charles, the Pekingese and the Pug. The breed was officially recognized in 1945. The Cavalier King Charles has a stronger structure and a longer muzzle than its cousin, the King Charles. It arrived in France in 1975 and a few years later, in 1983, a Spaniels Club English dwarves King Charles and Cavalier King Charles were created. The Cavalier King Charles, which has overshadowed the King Charles, is an increasingly popular breed.

The Cavalier King Charles is one of the small breeds with its 25 to 34 cm and 5 to 9 kg. It is a harmonious little dog, which moves with grace and flexibility with a lot of momentum at the rear. Its body is elongated but its neck remains of medium length, with a slight curve. Its chest is moderately broad, its ribs well sprung. Its back is straight and ends in a rather short loin area. Its limbs are short, supported by medium bones. Its feet are compact and have good pads. It carries its tail happily while not letting it extend too far beyond the line of its back. Its head is round and its skull almost flat. Its muzzle is conical. It has strong jaws, covered by non-dangling lips. Its small black nose is well developed. Its large dark eyes are round but should not be protruding. His ears, set high, are long and covered with abundant fringes. There are four coats for the Cavalier King Charles: the black and tan coat (similar to that of King Charles), the Ruby or Ruby coat, the Blenheim coat and the tricolor called “Prince Charles”. The black and tan coat is black, raven wing with tan spots above the eyes, on the cheeks, inside the ears, on the chest, limbs and under the tail. Some white marks are also allowed. The ruby color is one-color, intense red. No white mark is tolerated in the standard of this dress, which is also the rarest. The Blenheim coat has well-distributed bright brown markings on a pearl white background. These marks must split evenly at the level of the skull to leave room for the characteristic white spot or patch. The tricolor coat has black and white well spaced and distributed with a tan mark above the eyes, on the cheeks, inside the ears, limbs and under the tail. His hair is long, silky and without curls but with a slight waviness, especially at his abundant fringes.

The Kennel Club of Great Britain gives a life expectancy of around twelve years to the Cavalier King Charles. Mitral endocardiosis, a degenerative heart disease, is a major concern in this breed. In fact, almost all Cavalier King Charles breeds suffer from it. A study found that 82% of dogs aged 1 to 3 years old had this disease and 97% of dogs older than 3 years old suffered from this disease at different stages of its progression. This condition, which affects the mitral valve, can be found in its hereditary form and therefore appear very early or appear with the dog's old age. From a heart murmur, the disease gradually leads to heart failure. It often leads to the appearance of pulmonary edema and the subsequent death of the animal. There is no particular prevalence between male and female individuals nor between the different coats existing in this breed. Mitral endocardiosis has recently appeared in the Cavalier King Charles Spaniel; it is clearly the direct consequence of the poor selection of breeding stock within breeding grounds. The Cavalier King Charles is also predisposed to syringomyelia due to the digging of a cavity in the spinal cord. As this pathology progresses, the dog presents coordination difficulties and gradually more serious motor skills problems. An examination of the nervous system by magnetic resonance makes it possible to detect the disease and thus treat it using corticosteroids. The Cavalier King Charles is still subject to other diseases such as incomplete ossification of the humeral condyle, demodectic mange, pyoderma. , ear infections, allergic dermatitis, cataracts, corneal dystrophy, epilepsy, patellar dislocation and diabetes. Due to its long coat, it is recommended to brush and comb it two to three times a week. During these maintenance sessions, it is also recommended to monitor the condition of your eyes and ears. Grooming, on the other hand, is not necessary.
