The Cavapoo — a cross between a Cavalier King Charles Spaniel and a Poodle — is one of the fastest-growing crossbreeds in the UK, adored for their gentle temperament, moderate exercise needs, and low-shedding coats. However, the inherited health risks from the Cavalier parent make this one of the most medically important breeds to research before purchasing. This guide covers everything honestly.

The Critical Health Warning — Read This Before Purchasing
The Cavalier King Charles Spaniel parent breed carries two of the most serious inherited health conditions in the dog world. These conditions are passed into Cavapoos at significant rates. Responsible purchasing means understanding them before you search for a puppy:
Mitral Valve Disease (MVD)
MVD is the leading cause of death in Cavalier King Charles Spaniels — and the most common form of heart disease in dogs overall. Statistics from peer-reviewed research:
- Approximately 50% of Cavaliers have a characteristic heart murmur by age 5
- Nearly all surviving Cavaliers have at least a low-grade murmur by age 10
- MVD causes the mitral valve to thicken and leak, causing the heart to progressively enlarge and eventually fail
Because Cavapoos are 50% Cavalier (F1) or less, this risk is partially diluted — and Poodles are a healthier base breed. However, responsible Cavapoo breeders must MVD-screen the Cavalier parent to the KC/BVA Heart Scheme requirements:
- Cavalier parent should be heart clear at 2.5 years from a BVA-approved cardiologist
- Both parents of the Cavalier parent should also ideally be clear at age 2.5
Syringomyelia (SM)
Syringomyelia is a painful neurological condition where fluid-filled cavities develop in the spinal cord, typically caused by a malformation where the brain is too large for the skull (Chiari-like malformation). Research statistics are stark:
- Studies show over 90% of Cavaliers have the skull malformation (Chiari-like malformation)
- 25% of one-year-old Cavaliers and 70% of six-year-olds have syringomyelia (even if clinically silent)
- Symptoms: phantom scratching at the neck without making contact; yelping when touched around the neck; pain that is worse at night or in cold weather
MRI screening of the Cavalier parent is the only way to assess SM risk. This is expensive (£400–£600 per dog) which is why many breeders skip it — but it significantly changes the risk profile.
What to Ask a Cavapoo Breeder
- Has the Cavalier parent been heart-tested to BVA Heart Scheme standards (cardiologist certificate, minimum age 2.5 years)?
- Has the Cavalier parent been MRI-screened for Chiari-like malformation / syringomyelia?
- Has the Poodle parent been DNA tested for PRA-prcd (Progressive Retinal Atrophy)?
- Has the Cavalier parent been eye-tested at the BVA Eye Scheme?
- Can you see both parents? Visit the puppies at the breeder’s home?
Any breeder who has not done at minimum the heart test (#1) and PRA DNA test (#3) is producing puppies with knowable, preventable inherited disease without screening. Walk away.
Temperament
When health conditions are managed through responsible breeding, Cavapoos are outstanding companion dogs:
- Gentle and affectionate — the Cavalier’s sweet, calm nature combines beautifully with the Poodle’s intelligence
- Adaptable — suited to flats and houses, city and country, active and calmer households
- Good with children and other pets — non-aggressive, sociable, and patient
- Separation anxiety — a significant concern. Both parent breeds form strong human bonds. Systematic independence training from 8 weeks is essential. Cavapoos regularly appear in dog rescue statistics due to separation anxiety that owners couldn’t manage
- Trainable — the Poodle intelligence makes Cavapoos quick learners and responsive to reward-based training
Exercise, Grooming & Costs
Exercise: 1 hour daily is sufficient for most Cavapoos. They enjoy moderate walks, off-lead time, and mental games. They are not demanding athletes and suit owners with moderate activity levels.
Grooming: Similar to Cockapoos — continuous-growing, low-shedding coats that mat without regular maintenance:
- Home brushing 3–4 times per week (daily in curlier coats)
- Professional grooming every 6–8 weeks: £45–£75 per session. Annual cost: £350–£550
- Ear cleaning weekly — risk of ear infections due to floppy ears
Costs:
- Puppy: £1,000–£3,000 (health-screened lines cost more; this is appropriate pricing)
- Monthly insurance: £40–£80 (higher than average due to Cavalier heritage risk; lifetime policy essential)
- Monthly food: £30–£50 (small-medium breed)
- Estimated lifetime cost: £15,000–£25,000
FAQs
Are Cavapoos calmer than Cockapoos?
Generally, yes — the Cavalier parent brings a softer, less driven energy compared to the working Cocker Spaniel. Cavapoos tend to be slightly more laid-back. However, both breeds are sociable and moderately active, and individual variation is high. Neither breed is appropriate for an owner looking for a non-interactive, low-key dog — both need companionship and mental engagement.
