Toy spaniels can be traced back to at least the 16th century and were probably bred down from sporting spaniels. They became firmly established at the courts of Charles I and Charles II, and the first Duke of Marlborough developed the red and white Blenheim type at Blenheim Palace.
By the late 19th century, fashion favoured shorter muzzles and domed skulls. A group of breeders who missed the older, slightly larger type with a longer muzzle and flatter skull offered special prizes at Crufts from 1926. The name "Cavalier" was chosen to distinguish this old type from the flatter-faced King Charles. The breed club was formed in 1928, and the Kennel Club recognised the Cavalier as a separate breed in 1945.
Cavalier King Charles Spaniel temperament
Cavaliers are typically kind, gentle and loyal, with an easy-going nature. They are playful and, being spaniels, keep some prey drive and particularly enjoy hunting and chasing games.
They need company and can become very upset or develop separation anxiety when left alone, so they suit homes where someone is around most of the time. They do not tend to bark excessively, though they may bark when excited or when someone new comes to the door. Well-socialised Cavaliers usually get on with other dogs, and often prefer greeting passing people to passing dogs.
Size and appearance
Cavaliers are small dogs. Adults typically stand 30–33 cm at the shoulder and weigh 5.4–8.2 kg.
The coat is of medium length. Breed standard colours are Blenheim (chestnut and white), black and tan, ruby and tricolour.
How much exercise does a Cavalier King Charles Spaniel need?
Despite their size, Cavaliers are quite energetic and need at least an hour of exercise a day, ideally split into two or more walks with some off-lead time somewhere secure. Add play and regular training sessions, and they will enjoy free time in a secure garden.
They are adaptable and can be happy in a flat, a town or the countryside as long as they get enough exercise and mental stimulation. Many do well at agility.
Training a Cavalier King Charles Spaniel
Cavaliers are incredibly eager to please, which usually makes them fairly easy to train. With the right guidance they grow into obedient, confident dogs.
- Start positive, reward-based training from a young age, before bad habits form.
- Be consistent.
- Socialise your puppy with other dogs, different people and new experiences.
- Teach them gradually that being left alone is OK, and never leave them for more than four hours.
Cavalier King Charles Spaniel grooming
The coat is fairly high maintenance. Brushing more than once a week is recommended, and many Cavaliers need brushing daily to stop the coat matting. They shed, more so in spring and autumn, and some owners use a professional groomer a few times a year. Check the ears regularly, as the breed can be prone to ear problems.
Living with a Cavalier King Charles Spaniel
Cavaliers are known for making great family pets, and when well socialised they enjoy the company of people of all ages. Make sure your dog has somewhere quiet to retreat to when it wants time away from children or other pets, and step in if play gets too rough. Whatever the breed, dogs and young children should never be left alone together, and an adult should supervise every interaction.
Children
Often good with children, with supervision.
Other dogs
Usually sociable with other dogs.
Cats and small pets
Often lives with cats when introduced carefully.
Flats and smaller homes
Often adapts to flats and smaller homes.
Garden
A garden is helpful.
Being left alone
Usually copes only with short periods alone.
Cavalier King Charles Spaniel health
Not yet reviewed by a vet. This is general information, not veterinary advice: speak to your vet about your own dog’s health.
Like many pedigree dogs, Cavaliers are prone to certain health issues. Look for a breeder whose dogs have had the recommended screening, and ask about the health of the puppy's parents and grandparents. The Royal Kennel Club places the breed in Breed Watch category 2.
Mitral valve disease (MVD)
A degeneration of the heart's mitral valve, often first noticed as a heart murmur. It is common in older dogs of all breeds but starts earlier in Cavaliers. Many affected dogs still live to a good age. Breeding dogs should be graded under the Kennel Club heart scheme for Cavaliers.
Chiari malformation and syringomyelia (CM/SM)
A painful condition in which fluid-filled cavities develop within the spinal cord near the brain. Some dogs are seen scratching the air near the neck. Some show mild or no signs, while in others it progresses and causes pain and neurological problems. Diagnosis is by MRI scan, and there is a BVA/KC screening scheme.
Curly coat/dry eye (CC/DE)
A condition affecting the skin, coat, nails and eyes that can cause a severe form of dry eye. A DNA test is available, and the Royal Kennel Club recommends it as a minimum before breeding.
Episodic falling (EF)
A condition that seems unique to Cavaliers, in which the muscles stiffen and the body becomes rigid, often during exercise, excitement or stress. A DNA test is available.
Eye conditions
The main inherited eye conditions are cataracts and multifocal retinal dysplasia, both now much less common thanks to testing. Eye testing under the BVA/KC/ISDS Eye Scheme is recommended.
Patellar luxation
The kneecaps can slip temporarily out of place.
Dental disease
Bad teeth are common in all breeds, but potentially more so in Cavaliers because of their shorter muzzle.
What health checks should you ask about?
Responsible breeders and rescues are happy to talk about health, and any pressure to decide quickly is a reason to walk away. Before taking a Cavalier King Charles Spaniel home, it is reasonable to ask about:
- Health testing of the parents. Ask which health tests the parents have had for conditions known in the breed, and to see the results.
- Veterinary and vaccination records. Puppies should have had a first vaccination and a vet check, with records you can take home.
- Microchip information. In England, Scotland and Wales puppies must be microchipped and registered by eight weeks old. Ask who the chip is registered to and how the transfer works.
- Registration paperwork. Registration papers, where they apply, record pedigree. They do not by themselves prove health or how a puppy was raised.
How much does a Cavalier King Charles Spaniel cost to own?
There are two costs: bringing a Cavalier King Charles Spaniel home, and looking after one well. Puppy prices depend on the breeder, health testing and demand; the adverts below show what sellers are asking today.
Ongoing costs are the ones new owners most often underestimate: food, insurance (which usually rises with age), routine vet care, vaccinations and parasite treatment, dental care, grooming, training, bedding and equipment, and boarding or a sitter for holidays. Budget for the whole of the dog’s life, typically from 12 years, not just the first year.
Buying a Cavalier King Charles Spaniel
If you have decided the Cavalier King Charles Spaniel suits your life, take the same care choosing where your dog comes from. Meet the puppy in person, see it with its mother, and look at how the litter is raised.
- Check who you are dealing with: every Mypetzilla advert shows the seller type and what we have checked.
- Ask about health testing, vaccinations and the microchip before you commit.
- Take your time. Do not be rushed by deposits or "last one left" stories.
- Meet in person before paying anything, and keep conversations on Mypetzilla.
Adopting a Cavalier King Charles Spaniel
Cavalier King Charles Spaniels do come up for adoption, through rescue organisations, breed rescues and private rehoming, often because an owner’s circumstances have changed rather than any fault of the dog. An adult dog arrives as a known quantity: its size, coat and character are already on show.
Rescues will usually talk you through the dog’s history, any medical care, and the home it needs, including children, other animals and time alone. Be honest about your circumstances: a good rescue would rather place a dog once, well.
