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, affectionate and easygoing with people, kids and other pets.
The Cavalier King Charles Spaniel is a small toy breed built for companionship rather than work. Adults weigh between 13 and 18 pounds and stand roughly 12 to 13 inches at the shoulder, with a silky coat, large round eyes and long feathered ears that give the face its gentle look.
Temperament sets the breed apart. Cavaliers are warm, affectionate and quick to attach to their family, and they rarely meet a stranger they do not like. Most get on well with kids and other pets, which is why the breed turns up so often in family homes and with owners new to dogs.
A flat suits the Cavalier just as well as a house with a backyard, as long as it gets company and a moderate amount of exercise each day. Left alone for long stretches it tends to struggle, since it was bred to be with people rather than to work independently.
| Attribute | Detail |

| Origin | England |
| Size | Toy (13 to 18 lb) |
| Lifespan | 12 to 15 years |
| Group/role | Toy group, companion dog |
| Good with | Children, other dogs, and most pets |
The Cavalier suits people after a close, lap-loving companion who can offer regular attention, including families with children, older owners and households that already have other pets. It is not the right fit for anyone out of the house most of the day, since the breed is prone to separation distress and does best in company.
The Cavalier King Charles Spaniel traces back to the toy spaniels of the English court and was reshaped in the 1920s to match the longer-nosed dogs seen in old portraits.
Small toy spaniels kept company with English royalty for centuries, and by the reigns of King Charles I and King Charles II in the 1600s they were firmly linked with the Crown. King Charles II was so taken with the breed that the spaniels eventually took his name.
The type drifted over the following two hundred years. Crossbreeding with flat-faced Asian dogs shortened the muzzle and rounded the skull, producing the King Charles Spaniel, known in some countries as the English Toy Spaniel.
In the 1920s an American breed enthusiast, Roswell Eldridge, put up cash prizes at Crufts in England for spaniels built like the longer-nosed dogs painted by artists such as Van Dyck. Breeders took up the challenge and worked to bring that older look back, naming the resulting dogs Cavalier King Charles Spaniels to set them apart from the flatter-faced King Charles Spaniel.
The Kennel Club in England recognised the Cavalier as its own breed in 1945, and the American Kennel Club followed with full recognition in 1995. Dogs Australia, the national body responsible for pedigree registration here, recognises the breed too, and it remains a popular companion in homes across the country.
The Cavalier is a small, balanced spaniel with a silky coat, feathered ears, large dark round eyes and a gentle expression, shown in four traditional colours.
The Cavalier is a graceful toy dog with a compact, balanced frame. The head is slightly rounded with a shallow stop and a full muzzle, and the large, dark, round eyes set wide apart give the breed its soft, appealing expression. Long ears sit high on the head and hang close, carrying plenty of feathering, while the tail is well set on and carried level with the back, often moving gently when the dog is active.
| Trait | Standard |
|---|---|
| Height | 12 to 13 inches at the shoulder |
| Weight | 13 to 18 pounds |
| 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 and silky, with a slight wave allowed but no curl. Four colours are recognised. Blenheim is rich chestnut markings on a pearly white background, often with a chestnut spot on the crown of the head. Tricolour is black and white with tan markings above the eyes, on the cheeks and under the tail. Black and tan is a solid black coat with tan points, and ruby is a whole, single coat of rich red. Feathering on the ears, chest, legs and tail fills out more as the dog matures.
The Cavalier is gentle, affectionate and sociable, forming close bonds with its people and getting on easily with kids, strangers and other pets.
Few toy breeds are as people focused as the Cavalier. It is affectionate and gentle by nature, seeks out close contact with its owners, and will happily settle on a lap at any opportunity. Visitors are treated as friends rather than threats, so the breed makes a poor watchdog but a warm, sociable housemate.
Cavaliers are patient and playful with children, though time with young kids should always be supervised, as with any dog. They usually take to other dogs and household pets without fuss. Spaniel instincts still surface occasionally, and some Cavaliers will chase birds or small animals outdoors, so a secure yard or a lead is a sensible precaution.
Being left alone does not suit the breed. A Cavalier kept on its own for long hours can grow anxious and may bark, pace or chew. Energy levels sit in the middle range, with the dog happy to play and then settle, and it tends to pick up on the mood of the household around it.
| Trait | Rating |

| Affection | 5 |
| Energy | 3 |
| Trainability | 4 |
| Vocalness | 2 |
| Shedding | 3 |
The Cavalier needs regular brushing of its silky coat, moderate daily exercise and steady company, with extra attention paid to its long ears.
The Cavalier settles just as well into a flat as into a house with a yard. What matters most is human company and a comfortable, climate-controlled space, since the breed is sensitive to heat and should not be left outdoors in warm conditions. Australian summers bring real heat stress risk, so an air-conditioned spot indoors during the hottest months is worth planning for. 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 treats kept in check to avoid weight gain.
Feed a complete and balanced dog food suited to the dog's life stage. Because the Cavalier is small and inclined to put on weight, portion control matters more here than for many larger breeds. Measure out meals rather than leaving food down all day, and adjust the amount to keep a visible waist and ribs that are easy to feel. Fresh water should be available at all times.
| Life stage | Amount per day | Meals |
|---|---|---|
| Puppy (2 to 6 months) | About 1/2 to 1 cup, by growth and food | 3 to 4 |
| Puppy (6 to 12 months) | About 1/2 to 1 cup | 2 to 3 |
| Adult | About 1/2 to 1 cup | 2 |
| Senior | Adjusted to lower activity | 2 |
Keep treats to no more than about 10 percent of daily calories, since extra snacks add up fast on a dog this size. A balanced commercial diet usually covers all the nutrients a Cavalier needs, so only add supplements on veterinary advice. Dental chews can help with oral health, a common concern in toy breeds.
The Cavalier typically lives 12 to 15 years but is prone to mitral valve heart disease and syringomyelia, so heart and neurological screening matters.
The Cavalier King Charles Spaniel typically lives 12 to 15 years and stays an active companion when healthy, but the breed carries several well-documented inherited conditions, and responsible breeders screen their stock accordingly. Mitral valve disease is the most significant concern, a heart condition that shows up commonly in the breed and often earlier than in most others.
| 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 bright and keen to please, so it responds well to gentle, reward-based training, though toilet training can take patience.
The Cavalier wants to be near its people and is keen to please, so training usually goes smoothly. It is sensitive to tone and does not respond well to harsh correction, and short, upbeat sessions hold its attention far better than long drills. Early socialisation with new people, dogs, places and sounds helps a puppy grow into a confident adult, and toilet training can take longer than average for the breed, so a consistent routine and a bit of patience pay off.
Cavalier breeding centres on health screening, especially for heart and neurological conditions, with litters of three to five puppies after roughly two months' pregnancy.
Responsible breeding of the Cavalier King Charles Spaniel puts health screening ahead of everything else. Breeding stock should be assessed for mitral valve disease and, where programs exist, for syringomyelia, eyes and knees, and many breed clubs recommend dogs be older and clear of heart murmurs before they are bred, to cut down on early heart disease being passed on.
Females usually reach maturity within their first year, though breeders typically hold off until the dog is physically mature and has cleared health screening. Pregnancy runs about 63 days, and litters tend to be small, commonly three to five puppies. Because the breed is small, some births need veterinary support, so a vet should keep an eye on the pregnancy throughout.
Puppies stay with the mother for the first few weeks and usually go to new homes at around eight to twelve weeks old. Gentle early handling and exposure to everyday household life help puppies socialise well before they leave.
| Metric | Value |
|---|---|
| Sexual maturity | Around 6 to 12 months (breeding usually delayed) |
| 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 12 to 13 inches at the shoulder and weighing roughly 13 to 18 pounds fully grown.
Yes. The breed is gentle and sociable and generally gets on well with children and other animals. Time with young kids should still be supervised, as with any dog.
Care is moderate. The silky coat needs brushing several times a week, the ears need a weekly check, and the dog needs daily company and a modest amount of exercise. Keeping an eye on health, especially the heart, is the main ongoing job.
The typical lifespan is 12 to 15 years. Choosing a puppy from heart-screened parents and keeping the dog at a healthy weight both 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 home for much of the day.
Not for long. The breed is bred for company and can develop separation anxiety, so a household where the dog is alone for many hours is a poor fit.
Cavaliers are available through registered breeders and breed-specific rescue groups. Look for breeders who health-test their dogs for heart and, where possible, neurological conditions, and who register litters with a recognised pedigree body.
