Cavapoo

There is no breed standard for the Cavapoo's temperament; the soundest information we have is how the two parents are described. The Royal Kennel Club's Cavalier standard sums up the temperament as "gay, friendly, non-aggressive, no tendency to nervousness"; for the Poodle, the same club says "gay-spirited and good-tempered". What the two parents share is closeness to people, so a Cavapoo is usually expected to be a "companion dog".

That expectation has limits. In a 2026 UK study (Bryson et al.), owners of 9,402 dogs completed a behavior questionnaire; 985 of them were Cavapoos. The Cavapoos differed from Cavaliers and Poodles in 12 of 24 comparisons, and in 11 of those they scored worse (higher on undesirable behaviors) than their parents. The authors say beliefs such as "crossbreds need little training" or "they're especially good with children" aren't supported by evidence. That doesn't mean a Cavapoo will necessarily be a problem; it's a reminder to look at the individual dog and how it was raised.

A Cavapoo can suit people who want a small, affectionate dog that likes being with its person, and who take health screening seriously. The Royal Kennel Club considers both the Cavalier and the Toy Poodle suitable for flats and for homes with a small or medium garden.

The Cavapoo is a crossbreed, so its story is the story of its two parent breeds. According to the Royal Kennel Club, toy spaniels can be traced back to at least the 16th century, became well established in the courts of Charles I and his son Charles II, and are described as bred down from sporting breeds; the Blenheim spaniel retained its sporting instincts. The Poodle was bred in Germany as a water retriever for duck hunters.

We couldn't find a reliable record of exactly when and where the Cavapoo first appeared; there's no breed standard and no official pedigree register. The 2026 study by Bryson and colleagues describes the Cavapoo as one of the three most popular Poodle crosses in the UK. This popularity means each litter's parents need to be asked about individually.

There's no single standard for how a Cavapoo looks. The parent breed standards show the range:

• Cavalier King Charles Spaniel (Royal Kennel Club): Weight 5.4–8.2 kg (12–18 lb); long, feathered, drooping ears and a gentle expression. A medium-length coat.
• Toy Poodle (FCI): Over 24 cm up to 28 cm (9.5–11 in), ideal 25 cm. The Miniature Poodle is 28–35 cm (11–14 in). A frizzy coat, either curly or corded.
• In the cross: The coat may be straight, wavy or curly, and the color varies widely. Puppies in the same litter may not look alike.

When you pick up a puppy you can't know its adult size or coat type for sure. Seeing the parents is the best clue.

The Royal Kennel Club rates grooming as "more than once a week" for the Cavalier and "every day" for the Toy Poodle; the Cavalier sheds and the Poodle doesn't. In a cross, coat care depends on which parent the dog takes after more; be ready for regular brushing and periodic trims.

• Brushing: Catch tangles early in friction areas such as behind the ears, under the legs and on the belly. See our article on dog coat care for more.
• Ears: Check drooping, hairy ears once a week; show your vet any odor or redness. For the Cavalier, UFAW also lists otitis externa (outer ear infection) among its problems.
• Eyes: Keep the hair around the eyes short; show your vet any redness or watering.
• Teeth: Tartar builds up fast in a small mouth; brush teeth from puppyhood.
• Nails: Check regularly.

The Royal Kennel Club recommends up to an hour of exercise a day for both the Cavalier and the Toy Poodle. For a Cavapoo, short walks, play in the yard or at home and mental work are enough.

• Reward-based work: Positive, rewarded and consistent training works best in small dogs, too. Sniffing games tire the mind: sniffing games.
• Being alone: In people-oriented dogs, alone time has to be taught gradually.
• Behavior: The 2026 study found higher scores for some undesirable behaviors in Cavapoos; early socialization and consistent training matter even more for that reason.
• Neck pain: Because of the Cavalier's syringomyelia risk (below), show your vet if your dog cries out when picked up or when jumping.

A Cavapoo doesn't need a special food; a complete and balanced small-breed food suited to its age and size is enough.

• If you can feel the ribs under a thin layer of fat, the weight is good.
• Measure the food and subtract treats from the daily amount.
• Regular weigh-ins show weight changes early.
• Your vet decides the diet plan for a dog with heart disease.

We couldn't find a separate health study on the Cavapoo. So we're passing on the known issues of the two parent breeds and general information on crosses. The Cavalier side is serious, and we say so plainly. The following is for information only; ask your veterinarian for diagnosis and treatment.

Being a cross is not a health guarantee

VetCompass studies from the Royal Veterinary College show that crossbred dogs live on average 1.2 years longer than purebreds, but have lower rates in only three of the 20 most commonly recorded disorders. So crosses may get a "hybrid vigor" effect, but it doesn't make every problem go away. Whether a Cavapoo carries the Cavalier's inherited problems is shown by the parents' screening, not by looking at the puppy.

Mitral valve disease (heart)

Mitral valve disease (MVD) is a progressive disease in which a valve in the heart leaks over time and the heart enlarges and becomes less effective. According to UFAW, it's about twenty times more common in the Cavalier than in other breeds; a heart murmur can be detected from three or four years of age, about half have a murmur by five and nearly all by ten. Most develop heart failure within several years; signs include coughing, breathlessness and difficulty exercising. In a study of 1,749 Cavaliers with clinical records in England (Summers et al.), a heart murmur was recorded in 30.9% of the dogs, and heart disorders were the most common category. There is thought to be a genetic basis: UFAW estimates about 70% of dogs bred from affected parents are likely to inherit the condition. On the other hand, the results of a mandatory breeding scheme in Denmark are encouraging: in the study by Birkegård and colleagues, puppies whose parents had both passed the scheme's screening had a 73% lower risk of a heart murmur in 2010–2011 than in 2002–2003. The Royal Kennel Club's Cavalier heart scheme recommends cardiologist assessment from 18 months of age, ideally at 2, 4 and 6 years. So asking for the Cavalier parent's heart screening results is one of the most important questions when buying a Cavapoo.

Syringomyelia (Chiari-like malformation)

Syringomyelia is the formation of fluid-filled cavities in the spinal cord of the neck, linked to a mismatch between the size of the brain and the skull. According to UFAW, in a survey of 555 Cavaliers with no clinical signs scanned by MRI, 25% of one-year-olds and 70% of those aged six years or more had syringomyelia; in a US survey 3.4% of Cavaliers showed clinical signs (pain). The earliest sign is often yelping after a sudden change of posture, such as jumping down or being picked up; in more severe cases there can be sensitivity to touch around the neck, uncontrollable scratching at the ears, chest and shoulders, and difficulty walking. According to UFAW the pain can last for years. Diagnosis is by MRI; breeders are advised to scan at one year, at two to three years and at six years. What this means for a Cavapoo: if you see signs of neck pain or scratching episodes, go to your vet; before getting a puppy, ask for the Cavalier parent's MRI result.

Other Cavalier issues

UFAW's Cavalier list also includes congenital dry eye (keratoconjunctivitis sicca) and a skin condition, outer ear infection, pancreatitis, slipping kneecaps and fluid in the middle ear. The Royal Kennel Club also recommends DNA tests for curly coat / dry eye (CC/DE) and episodic falling (EF) and an eye exam for the Cavalier. On the Poodle side, it recommends the prcd-PRA DNA test for the Toy Poodle, and UFAW's list includes diabetes, extra eyelashes, hereditary cataract and hyperadrenocorticism. It isn't known how often these occur in the Cavapoo.

Flat-face (BOAS) considerations

In a 2026 study published in PLOS One, the Cavalier was among the "mild risk" flat-faced breeds; the Poodle isn't flat-faced. A Cavapoo's face structure may resemble the Cavalier's or the Poodle's more. If you notice noisy breathing, snoring or tiring quickly on exercise, show your vet.

The "teacup" and "mini" myth

Cavapoo sellers often use labels like "mini", "micro" or "teacup". The RSPCA says those words can be signs puppy dealers use to attract attention. Look at the parents' screening rather than the size.

We couldn't find a separate lifespan figure for the Cavapoo. For the Cavalier parent, UK data give a life expectancy at birth of 10.45 years (Teng et al., 2022). The Royal Kennel Club lists the Poodle's lifespan as "over 12 years". We don't know the right number for the Cavapoo; the heart-disease risk from the Cavalier may be one of the most decisive factors for lifespan.

Regular vet checks, a healthy weight, having the heart listened to regularly and catching neck and back signs early are the most concrete ways to help.

• Consider a shelter too: Small crosses also end up in shelters. Our article on adopting a dog from a shelter covers the first steps.
• If you buy from a breeder: Ask to see the mother and father. Ask for the Cavalier parent's heart screening (the Royal Kennel Club scheme or an equivalent), the MRI result for syringomyelia and the eye exam; and the Poodle parent's eye exam and DNA tests. Find out which size of Poodle was used. See the puppies raised with their mother in a home environment.
• Be careful with "hypoallergenic" promises: A seller who says "it never sheds and won't cause allergies" is making a claim science doesn't support (see the questions below).
• Red flags: Stay away from sellers who won't show screening documents, demand an instant deposit or sell many "mini" puppies at once. The RSPCA also treats the same phone number appearing in several adverts as a warning sign.
• Time and budget: Be ready for regular grooming, dental care and possible heart or neurology checks later on.
• Legal registration: In Türkiye, owned dogs must be microchipped and registered in the PETVET system. See our article on PETVET registration and microchips.
