The Cavalier King Charles Spaniel is an affectionate, gentle companion known for its sweet temperament and eager devotion to everyone it meets.
How the Cavalier King Charles Spaniel coat is built, and what that means when you groom it.
Caution: A Cavalier King Charles Spaniel coat mats easily.
Fine or long hair tangles at the base of the coat, out of sight, where the mats tighten and pull on the skin. Brushing has to reach right down to the roots in sections, not just skim the surface.

The Cavalier King Charles Spaniel is a toy companion breed from England, valued for an affectionate, gentle temperament and easy sociability with people and other pets.
The Cavalier King Charles Spaniel is a small companion breed in the toy group. It typically weighs between 5.9 and 8.2 kilograms and stands roughly 30 to 33 centimetres at the shoulder. The breed is recognised for a soft, silky coat, large round eyes, and long feathered ears that frame an expressive face.
Temperament is the defining characteristic. Cavaliers are friendly, affectionate, and gentle, and they tend to bond closely with their household. They greet strangers warmly and generally get on well with children and other animals, which makes them a frequent choice for families and for owners new to dogs.
The breed adapts to many living situations. A Cavalier is comfortable in a flat or a house, provided it receives daily companionship and moderate exercise. It does not thrive when left alone for long stretches, as it is bred for human company rather than independent work.
| Attribute | Detail |
|---|---|
| Origin | England |
| Size | Toy (5.9 to 8.2 kg) |
| Lifespan | 12 to 15 years |
| Group/role | Toy group, companion dog |
| Good with | Children, other dogs, and most pets |
The Cavalier suits people who want a close, lap-friendly companion and who can offer regular attention throughout the day. It works well for families with children, older owners, and households with other pets. It is a poor match for anyone away from home for most of the day, as the breed is prone to separation distress and is happiest in company.
The Cavalier King Charles Spaniel descends from the small toy spaniels of the English royal court and was reconstructed in the 1920s to match the longer-nosed dogs depicted in old paintings.
Small toy spaniels served as companions in the English court for centuries. By the time of King Charles I and King Charles II in the 1600s, these spaniels were closely associated with royalty, and King Charles II was so fond of them that the small spaniels later carried his name.
Over the following two centuries the type changed considerably. Crossing with flat-faced Asian breeds pushed the toy spaniel towards a shorter muzzle and a domed skull, producing the look that became the King Charles Spaniel, known in some countries as the English Toy Spaniel.
In the 1920s an American enthusiast, Roswell Eldridge, offered prize money at Crufts for spaniels of the older, longer-nosed type shown in paintings by artists such as Van Dyck. Breeders worked to recover that earlier form, and the resulting dogs were named Cavalier King Charles Spaniels to distinguish them from the flatter-faced King Charles Spaniel.
The Cavalier was recognised as a separate breed by The Kennel Club in 1945. The American Kennel Club granted full recognition in 1995. The breed has since become a popular companion in many countries.
The Cavalier is a small, well-balanced spaniel with a silky coat, long feathered ears, large dark round eyes, and a gentle expression, recognised in four traditional colour patterns.
The Cavalier is a graceful toy dog of compact, balanced build. The head is slightly rounded with a shallow stop and a full muzzle. The large, dark, round eyes set wide apart give the breed its soft, appealing expression. Long, high-set ears hang close to the head and carry abundant feathering. The tail is well set on and carried level with the back, often in gentle motion when the dog is active.
| Trait | Standard |
|---|---|
| Height | 30 to 33 cm at the shoulder |
| Weight | 5.9 to 8.2 kg |
| Coat | Long, silky, free of curl, with feathering on ears, legs, chest, and tail |
| Colours | Blenheim, tricolour, black and tan, ruby |
| Eyes | Large, round, dark brown, set well apart |
The coat is moderately long, silky, and may have a slight wave but no curl. Four colours are recognised. Blenheim is rich chestnut markings on a pearly white ground, often with a chestnut spot on the crown of the skull. Tricolour is black and white with tan markings above the eyes, on the cheeks, and beneath the tail. Black and tan is a solid black coat with tan points. Ruby is a whole, single coat of rich red. Feathering on the ears, chest, legs, and tail develops more fully as the dog matures.
The Cavalier is gentle, affectionate, and sociable, bonding closely with its owners and getting on easily with children, strangers, and other pets.
The Cavalier is one of the most people-oriented toy breeds. It is affectionate and gentle, and it seeks close contact with its owners, often settling on a lap when the opportunity arises. The breed greets visitors as friends rather than threats, which makes it a poor guard dog but a warm, sociable housemate.
With children the Cavalier is patient and playful, though time with young children should be supervised, as with any dog. It typically accepts other dogs and household pets without difficulty. Spaniel instincts remain present, and some Cavaliers will chase birds or small animals outdoors, so a secure garden or a lead is sensible.
The breed dislikes being alone. A Cavalier left for long hours can become anxious and may bark, pace, or chew. It is moderate in energy, content to play and then rest, and it tends to reflect the mood of the household.
| Trait | Rating |
|---|---|
| Affection | 5 |
| Energy | 3 |
| Trainability | 4 |
| Vocalness | 2 |

The Cavalier needs regular brushing of its silky coat, modest daily exercise, and steady companionship, with particular attention to its long ears.
The Cavalier adapts well to flats and houses alike. Human company and a comfortable, temperature-controlled space matter most. The breed is sensitive to heat and should not be left outdoors in warm conditions. It is an indoor companion that wants to be near its people.
The Cavalier needs a complete, balanced diet portioned to its small size, with careful control of treats to prevent weight gain.
Feed a complete and balanced dog food appropriate to the dog's life stage. Because the Cavalier is small and inclined to put on weight, portion control matters more than for many breeds. Measure meals rather than free-feeding, and adjust amounts to maintain a visible waist and easily felt ribs. Fresh water should always be available.
| Life stage | Amount per day | Meals |
|---|---|---|
| Puppy (2 to 6 months) | About 55 to 110 g, adjusted for growth and food type | 3 to 4 |
| Puppy (6 to 12 months) | About 55 to 110 g | 2 to 3 |
| Adult | About 55 to 110 g | 2 |
| Senior | Adjusted to lower activity | 2 |
Keep treats to no more than roughly 10 per cent of daily calories, as extra snacks accumulate quickly in a 7-kilogram dog. A balanced commercial diet usually supplies all required nutrients, so supplements should be given only on a veterinary surgeon's advice. Dental chews can support oral health, which is a common concern in toy breeds.
The Cavalier generally lives 12 to 15 years but is predisposed to mitral valve heart disease and a neurological condition called syringomyelia, so heart and neurological screening is important.
The Cavalier King Charles Spaniel has a typical lifespan of 12 to 15 years. It is an active companion when healthy, but the breed carries several well-documented hereditary conditions, and responsible breeders screen their stock. The most significant concern is mitral valve disease, a heart condition that appears commonly and often earlier than in many other breeds. The Kennel Club and breed clubs in the UK operate health-testing schemes that prospective owners should ask breeders about.
| Condition | Signs | Note |
|---|---|---|
| Mitral valve disease | Heart murmur, coughing, reduced stamina | The leading health concern; ask about heart-screened parents |
| Syringomyelia | Scratching at the neck, sensitivity, pain | A condition where fluid-filled cavities form near the spinal cord |
| Ear infections | Head shaking, odour, scratching at ears | Linked to the long, hairy ears; routine cleaning helps |
| Patellar luxation | Skipping gait, intermittent hind-leg lameness | A kneecap that slips out of place, seen in toy breeds |
| Eye disorders | Cloudiness, redness, vision changes | Includes cataracts and dry eye |
The Cavalier is intelligent and eager to please, which makes it responsive to gentle, reward-based training, though housetraining can take patience.
The Cavalier wants to be with its people and is keen to earn approval, so it usually responds well to training. It is sensitive to tone and does not handle harsh correction well. Short, positive sessions hold its attention better than long drills. Early socialisation with new people, dogs, places, and sounds helps the puppy develop into a confident adult. Housetraining can be slower than average for the breed, so a consistent routine and patience are required.
Cavalier breeding centres on health screening, especially for heart and neurological conditions, with a typical litter of three to five puppies after roughly a two-month pregnancy.
Responsible breeding of the Cavalier King Charles Spaniel places health screening ahead of all else. Breeding stock should be assessed for mitral valve disease, and where programmes exist, for syringomyelia, eyes, and knees. Many breed clubs recommend that dogs be older and clear of heart murmurs before being bred, to reduce the inheritance of early heart disease. The Kennel Club's health-testing schemes offer a structured framework for UK breeders.
Females generally reach maturity in their first year, but breeding is normally deferred until the dog is physically mature and has passed relevant health checks. Pregnancy lasts roughly 63 days. Litters are small, commonly three to five puppies. Because the breed is small, some births may require veterinary support, and a vet should monitor the pregnancy throughout.
Puppies are raised with the mother for the first weeks and are typically placed in new homes at around eight to twelve weeks of age. Early gentle handling and exposure to household life support good socialisation before the puppies leave.
| Metric | Value |
|---|---|
| Sexual maturity | Around 6 to 12 months (breeding usually deferred) |
| Gestation | About 63 days |
| Typical litter size | 3 to 5 puppies |
| Weaning | About 6 to 8 weeks |
| Recommended placement age | 8 to 12 weeks |

Common questions about the Cavalier King Charles Spaniel cover its size, temperament, care needs, lifespan, suitability, and availability.
It is a toy breed, standing about 30 to 33 centimetres at the shoulder and weighing roughly 5.9 to 8.2 kilograms when fully grown.
Yes. The breed is gentle and sociable and generally does well with children and other animals. Time with young children should be supervised, as with any dog.
Care is moderate. The silky coat needs brushing several times a week, the ears need weekly checks, and the dog needs daily companionship and modest exercise. Health monitoring, especially of the heart, is the main ongoing responsibility.
The typical lifespan is 12 to 15 years. Choosing a puppy from heart-screened parents and keeping the dog at a healthy weight support a longer, healthier life.
Yes. Its friendly nature, willingness to please, and moderate size make it a common choice for first-time owners, provided someone is at home for much of the day.
Not for long. The breed is bred for company and can develop separation anxiety. Households where the dog is alone for many hours are a poor fit.
Cavaliers are available through breeders and through breed-specific rescue groups. Look for breeders who health-test their dogs for heart and, where possible, neurological conditions. The Kennel Club's Find a Puppy service lists assured breeders in the UK.
