How long do Cavoodles live?
Most Cavoodles live 12 to 15 years. Where an individual dog lands in that range depends heavily on its heart. The Cavalier King Charles Spaniel parent carries a very high rate of mitral valve disease, the condition that cuts short many Cavaliers’ lives, while Poodles are generally long-lived. A Cavoodle bred from parents with cardiologist-cleared hearts has the best chance of reaching the upper end of the range.
The steps that make the most difference: choose a breeder who heart-tests both parents, keep the dog lean, ask your vet to listen to its heart at every annual check from about five years of age, and act early on any murmur.

Australia’s default family dog — and what that popularity hides
The Cavoodle is a cross between a Cavalier King Charles Spaniel and a Poodle, most often a Miniature Poodle. It has become one of the most commonly owned dogs in Australian cities, and the reasons are legitimate: it is small enough for an apartment, it sheds very little, it is unusually people-oriented, and it trains readily. None of that is marketing.
What the popularity obscures is that the Cavoodle inherits from a parent breed with two of the most serious and best-documented inherited conditions in veterinary medicine. Buying one without understanding the Cavalier side is the single most expensive mistake a new owner can make with this dog.
Mitral valve disease: the condition that defines this cross
Myxomatous mitral valve disease is a degenerative heart-valve condition, and in the Cavalier King Charles Spaniel its prevalence is roughly twenty times that of other breeds. About half of Cavaliers have a heart murmur by five years of age, and nearly all surviving Cavaliers have one by ten (UFAW summary of UK and US studies). A Cavoodle inherits half its genome from that line.
This does not mean every Cavoodle will develop heart disease. It does mean the question you ask a breeder is specific and non-negotiable: have both parents been auscultated by a veterinary cardiologist, and at what age? The established breeding protocol holds that no Cavalier should be bred under 2.5 years of age with a heart clear on cardiologist examination, and that its own parents should have been clear at five. Mandatory auscultation-and-echocardiography schemes have been shown to reduce disease prevalence measurably over an eight-to-ten-year period, so this screening demonstrably works — but only if the breeder actually does it.
Practically: from about five years of age, ask your vet to listen to the heart at every annual visit rather than only when something seems wrong. A murmur found early is a monitoring plan; a murmur found at the point of coughing and exercise intolerance is a management problem.
Chiari-like malformation and syringomyelia
The second Cavalier inheritance is neurological. Syringomyelia is a fluid-filled cavity forming within the spinal cord, secondary to a skull malformation that crowds the hindbrain. MRI screening studies of 1,020 and 555 Cavalier King Charles Spaniels found it in 39% and 46% of dogs (reviewed in Limpens et al., Frontiers in Veterinary Science, 2024). It is diagnosed by MRI, and screening protocols recommend imaging at three years or older.
The signs are easy to misread as behavioural: scratching at the neck and shoulder without making contact (often called air-scratching), yelping when picked up or when the collar is touched, and reluctance to be handled around the head. If your Cavoodle does this, it is worth a veterinary neurological opinion rather than a training intervention.
What the Poodle side contributes
The Poodle line brings progressive retinal atrophy, which is DNA-testable — ask for the parents’ prcd-PRA results, since a straightforward genetic test makes this one entirely avoidable in a well-planned litter. It also brings patellar luxation, and the coat.
That curly-to-wavy coat sheds very little, which is why the breed is often described as allergy-friendly. It is not hypoallergenic; no dog is. And low shedding again means the coat mats rather than drops, so weekly brushing at home is the baseline and a professional groom every six to eight weeks is a fixed recurring cost, not an optional indulgence. Budget for it before you buy.
Drop ears combined with hair growing in the ear canal make otitis externa a recurring theme in this cross. Dry the ears thoroughly after swimming and bathing, and have them checked at each groom.
Temperament, exercise and time alone
The Cavoodle is a moderate-energy dog: around forty-five minutes of daily activity, split between physical exercise and something that occupies the mind, meets its needs comfortably. It is bright — the Poodle side ranks near the top of working-intelligence assessments — and responds well to short, frequent, reward-based training sessions.
The trade-off is attachment. This is a dog bred, on both sides, to be in a person’s company. Separation distress is common and is best prevented rather than treated: build tolerance for solitude in small increments from the first week home, and avoid making departures and returns emotionally significant events.
Registration and ownership in Australia
In Victoria, dogs must be microchipped and registered with the local council from three months of age under the Domestic Animals Act 1994, with annual renewal on 10 April. Desexed registration across the Victorian councils in our fee survey ranged from about $19.50 to $93.30 a year, while entire dogs are charged several times that in most municipalities.
If you are buying rather than adopting, Cavoodle demand in Australia has attracted volume breeding operations. A breeder who cannot show you cardiologist certificates for both parents, or who will not let you meet the mother with the litter, is worth walking away from — the health screening described above is the whole difference between a fifteen-year dog and a difficult one.
Registration is set by your local council. In Victoria, registering a desexed Cavoodle costs between $19.50 and $93.30 a year depending on where you live, and roughly three times that if the dog is not desexed. See every Victorian council’s 2026–27 fee, or compare registration costs in every state.
Related breeds
The Cavoodle, a designer hybrid originating from Australia, is known for its small size (5-12 kg) and average lifespan of 12 to 15 years. It has a curly or wavy coat that sheds minimally, making it partially hypoallergenic. The breed exhibits high sociability, making it suitable for families with children and other pets. Due to its moderate energy level, the Cavoodle requires 30 to 60 minutes of daily exercise. Weekly home grooming is typically sufficient, although professional care may be needed periodically. The breed is prone to several health issues such as Mitral Valve Disease, Hip Dysplasia, Progressive Retinal Atrophy, Ear Infections, and Patellar Luxation. Cavoodles have a moderate separation anxiety and obesity risk, thereby necessitating regular medical checkups and weight management. First-year ownership costs are approximately $6000 with subsequent annual veterinary costs estimated at $1296. A contingency fund of $1440 is advisable for unexpected healthcare needs.
Due to the breed's predisposition to Mitral Valve Disease, Hip Dysplasia, Progressive Retinal Atrophy, Ear Infections, and Patellar Luxation, regular veterinary checkups are crucial. Preventative care includes dental hygiene, vaccinations, and weight management to mitigate health risks.
Daily care for a Cavoodle involves 30 to 60 minutes of exercise, such as walking or playing. Weekly grooming is needed to maintain their coat, and periodic professional grooming is advisable. Nutritionally balanced meals and portion control are critical to prevent obesity.
