A Cavalier King Charles Spaniel weighs about as much as a mid-size bag of kibble. A Labrador can weigh five times that. Cross the two, and you get the Cavador: a sweet, soft-eyed, people-loving dog that usually lands somewhere in the middle, both in size and in energy.
The Cavador is a cross between a Cavalier King Charles Spaniel and a Labrador Retriever. Most weigh about 25 to 55 lbs and stand 14 to 22 inches tall, with a gentle, affectionate, easy-to-train temperament. It’s a lovely family dog, and the one thing I’d research before anything else is heart health, because Cavaliers carry a very high risk of mitral valve disease.
What is a Cavador?
A Cavador is a mix of the Cavalier King Charles Spaniel and the Labrador Retriever. It’s a designer mix, not a recognized breed, and it’s still fairly uncommon. Because the parents are so different in size, these litters usually come from a Lab mother, often through artificial insemination, which is safer for whelping.
Here are the quick facts I’d want first:
| Trait | What to expect |
|---|---|
| Parent breeds | Cavalier King Charles Spaniel and Labrador Retriever |
| Height (inches) | About 14 to 22 |
| Weight (lbs) | About 25 to 55 |
| Lifespan (years) | About 10 to 14 |
| Coat | Short and dense, or medium and wavy with feathering |
| Colors | Black, chocolate, yellow, ruby, Blenheim, tricolor |
| Energy | Moderate |
| Good with kids | Yes, usually excellent |
| Good for first-time owners | Yes |
These ranges are my estimates, based on the AKC figures for both parents. With a size gap this big, the range in a single litter can be wide.
Where the Cavador comes from
The Cavador showed up during the designer-dog boom of the late 20th and early 21st centuries. Breeders wanted a dog with the Cavalier’s gentle, cuddly nature and the Lab’s sturdier body and trainability, in a medium size that fits more homes than a full-size Lab.
The two parents have very different backgrounds, and I find the Cavalier’s story the more surprising one. It descends from the toy spaniels kept by British royalty, especially King Charles II in the 1600s, who was famously rarely seen without them. Today’s Cavalier was rebuilt in the 1920s to look like the spaniels in old paintings. The AKC Cavalier profile describes it as affectionate, gentle and graceful, a true lap dog.
The Lab was a working water dog from Newfoundland, later refined in Britain as a gun dog, and it’s famous for a friendly, adaptable temperament.
So you’re crossing a dog bred to sit on laps with a dog bred to fetch ducks from cold lakes. I think that’s what makes Cavadors such good all-rounders.
Size and appearance
I’d describe most Cavadors as medium-sized, with a Lab-like body on a smaller frame, a gentle face, large dark eyes and long, soft, feathered ears from the Cavalier.
This is how the parents compare, using AKC figures:
| Dog | Height (inches) | Weight (lbs) | Lifespan (years) | My take |
|---|---|---|---|---|
| Labrador Retriever | 21.5 to 24.5 | 55 to 80 | 11 to 13 | Buck’s a solid 78 |
| Cavalier King Charles Spaniel | 12 to 13 | 13 to 18 | 12 to 15 | A lap dog, by design |
| Cavador (estimate) | 14 to 22 | 25 to 55 | 10 to 14 | Lab-shaped, smaller |
That’s a huge gap, which is why I’d ask a breeder about the parents’ exact sizes and any previous litters. A Cavador from a big field-line Lab will grow much larger than one from a petite show-line Lab.
Colors
Cavadors come in plenty of colors, and I like the variety. Here’s what I’d expect:
- Black, often with a white chest
- Chocolate or liver
- Yellow or gold
- Ruby, a rich solid red from the Cavalier
- Blenheim, chestnut patches on white
- Tricolor, black and white with tan points
The Cavalier’s patterned colors are less common in first-generation Cavadors because the Lab’s solid colors tend to dominate, but they do show up.
Coat
The coat can be short and dense like the Labrador’s double coat, or medium-length, soft and wavy with feathering on the ears, legs, chest and tail like a Cavalier’s. Many land in between. Both parents shed, so a Cavador isn’t low-shedding or hypoallergenic.

Cavador temperament and personality
Most Cavadors I’ve read about are friendly, affectionate and gentle. They usually love children, get along with other dogs and cats, and greet visitors happily. They want to be near you, often on you.
This is how the parents compare:
| Trait | Labrador | Cavalier | The Cavador |
|---|---|---|---|
| Friendliness | Very high | Very high | Very high |
| Energy (AKC score, 1 to 5) | 5 | 3 | 3 to 4 |
| Trainability (AKC score, 1 to 5) | 5 | 4 | 4 to 5 |
| Barking (AKC score, 1 to 5) | 3 | 3 | Moderate |
| Tolerance for being alone | Moderate | Low | Low |
The last row matters most for many families. Cavaliers were bred purely as companions, and they don’t like being left alone. Combined with a Lab’s love of people, many Cavadors are prone to separation anxiety. I’d practice short absences from day one.
Cavadors aren’t guard dogs, and I wouldn’t pick one for that. A stranger would probably get a wagging tail and a nudge for petting.
Training a Cavador
Cavadors are smart, eager and food-motivated, and I think that’s a winning combination, which makes them one of the easier mixes to train. Positive reinforcement works beautifully: small treats, praise and play for the right behavior. Cavaliers can be sensitive, so harsh corrections tend to backfire.
The order I’d train in:
- Socialization from 8 weeks: people, kids, other dogs, car rides, vet visits.
- House training, with frequent trips outside and rewards.
- Sit, down, stay and come.
- Loose-leash walking.
- Short alone-time practice in a crate, building up slowly.
Short sessions of 5 to 10 minutes, a few times a day, work better than one long lesson. From my experience with retrievers, the dogs that settle best at home are the ones that get regular brain work, so add puzzle feeders and simple tricks once the basics are solid.
Exercise needs
A healthy adult Cavador usually needs about 45 to 60 minutes of activity a day. That’s less than a Lab, more than a Cavalier. Walks, fetch, swimming and play in a fenced yard all work, and many Cavadors love water.
| Age | Daily exercise | Good activities | Go easy on |
|---|---|---|---|
| Puppy (to 12 months) | Short sessions, several a day | Play, sniff walks, training | Long runs, jumping |
| Adult (1 to 8 years) | 45 to 60 minutes | Walks, fetch, swimming, games | Hard exercise in heat |
| Senior (8+) | 20 to 40 minutes | Gentle walks, sniff games | Long hikes |
Mental work matters too. Hide-and-seek with treats, snuffle mats and short trick sessions tire a Cavador out as well as a walk. A frozen KONG stuffed with peanut butter keeps Buck busy for about 2 hours, and it’s a good trick for alone time with a Cavador too.
Because of the heart risk from the Cavalier side, I’d watch for any sign that your dog tires more easily than usual on walks, coughs, or breathes hard at rest, and mention it to your vet.
Cavador health and lifespan
Most Cavadors live about 10 to 14 years. The AKC lists 11 to 13 years for the Lab and 12 to 15 for the Cavalier.
Mixed breeding can widen the gene pool, but it doesn’t make a puppy immune to its parents’ problems. These are the ones I’d watch for:
| Condition | From which parent | Watch for | When to call the vet |
|---|---|---|---|
| Mitral valve disease | Cavalier | Heart murmur, cough, tiring easily, fast breathing at rest | At every checkup, sooner with symptoms |
| Syringomyelia | Cavalier | Scratching at the neck or ear, pain, yelping | Within a few days |
| Hip and elbow dysplasia | Both | Limping, stiffness, bunny hopping | If it lasts more than a day or two |
| Ear infections | Both | Head shaking, smell, scratching | Within a few days |
| Eye problems (PRA, cataracts) | Both | Cloudy eyes, night blindness | At the next checkup |
| Obesity | Labrador | No waist, ribs hard to feel | At the next checkup |
Mitral valve disease is the big one, and I’d never gloss over it. It’s a degenerative condition of the heart valve, and it’s the leading cause of death in Cavaliers. According to CavalierHealth.org’s overview of mitral valve disease, statistics suggest it may affect over half of Cavaliers by age 5 and nearly all by age 10. A Cavador may inherit some of that risk.
What I’d do about it:
- Ask the breeder for the Cavalier parent’s heart clearances from a board-certified cardiologist, ideally at 2.5 years or older with no murmur
- Have your vet listen to your Cavador’s heart at every checkup
- Learn to count resting breathing rate at home; your vet can tell you what’s normal for your dog
- Keep your dog lean, which eases the load on the heart
VCA Animal Hospitals explains the stages of mitral valve disease and how it’s managed. Syringomyelia, where fluid-filled cavities form in the spinal cord, is another Cavalier problem worth asking breeders about.
I’m not a vet. If your Cavador coughs, tires easily or breathes fast while resting, book a visit.
Feeding a Cavador
Feed a complete, balanced food suited to your Cavador’s size and life stage, with a named meat protein as the first ingredient. Start with the label amount for your dog’s weight, then adjust by body condition.
What I’d keep in mind:
- Feed two measured meals a day (I’d use a kitchen scale, not a scoop)
- Count treats, which add up fast on a medium-sized dog
- Use a slow feeder if your Cavador gulps its food
- Check the ribs every couple of weeks
Both parents love food, and weight gain is common. It also puts strain on joints and the heart. Around age six, Buck started gaining weight on unchanged portions. A higher-protein, lower-calorie food split into three small meals brought him back to 78 lbs within four months. Ask your vet before adding omega-3s, joint supplements or probiotics.
Grooming
Grooming depends on the coat, and I’d plan for the fluffier one. Short Lab-type coats need weekly brushing. Feathered Cavalier-type coats need brushing several times a week to prevent tangles, especially behind the ears and on the legs.
My grooming kit for a Cavador:
- A slicker brush for feathering
- A metal comb for behind the ears
- A rubber curry brush for short coats
- Ear cleaner, since long, heavy ears trap moisture
- Nail clippers or a grinder
Check and clean the ears weekly, trim nails every few weeks and brush teeth several times a week. Cavaliers are prone to dental disease, so daily brushing is even better.
Is a Cavador right for you?
Based on my research, the happiest Cavadors live with families who are home a lot and love having a dog close by. Here’s my honest take.
A Cavador is a good fit if:
- You’d love a gentle, affectionate family dog that follows you everywhere
- Someone is home for much of the day
- Moderate daily exercise suits you
- You’ll keep up with heart checks and vet visits
Skip it if:
- The dog would be alone for 8 hours or more
- You want a guard dog
- A low-shedding dog matters to you
- You’re looking for a running or hunting partner
Finding a Cavador
I’d check Lab and Cavalier rescues first, because I think adoption deserves the first look, and mixed-breed rescues too. An adult Cavador’s size, coat and personality are already clear, which takes the guesswork out of a mix with such different parents.
If you buy a puppy, look for a breeder who:
- Shows cardiologist heart clearances for the Cavalier parent
- Has OFA or PennHIP hip and elbow results for the Lab parent
- Provides eye exams and DNA test results for both
- Lets you meet the mother and see where the puppies are raised
- Explains how the litter was bred and whelped safely
Here’s a look at Cavador puppies and what they’re like at home:
Skip any breeder who brushes off questions about heart health.
FAQ
How big does a Cavador get?
Most Cavadors grow to about 14 to 22 inches tall and 25 to 55 lbs. The size depends on the parents, especially the Lab, so ask the breeder about the parents’ weights. Lab-leaning puppies tend to be bigger.
Are Cavadors good family dogs?
Yes, Cavadors are usually gentle, affectionate and very good with children and other pets. They need daily exercise and company, and they don’t like being left alone for long. They suit families with someone home for much of the day.
Do Cavadors shed?
Yes, Cavadors shed. Both parents have coats that shed, and Lab-leaning dogs with a double coat shed more in spring and fall. Brush weekly for short coats and several times a week for feathered ones. Cavadors aren’t hypoallergenic.
How long do Cavadors live?
Cavadors usually live about 10 to 14 years. The AKC lists 11 to 13 years for Labs and 12 to 15 for Cavaliers. Heart health from the Cavalier side is the biggest factor, so regular heart checks matter.
Are Cavadors healthy?
Cavadors can be healthy dogs, but they may inherit mitral valve disease and syringomyelia from the Cavalier side, and joint problems from the Lab side. Choose a breeder who health-tests both parents, and keep up with vet checks.
My final word
A Cavador is the kind of dog that follows you from room to room and then lies on your feet once you sit down. Give it moderate exercise, plenty of company and regular heart checks, and you’ll have a sweet, easygoing companion for many years.
