Ca de Bou scorecard
Overview
The Ca de Bou, also known as the Perro Dogo Mallorquín or Majorca Mastiff, is a powerful molosser breed from the Balearic island of Majorca. Standing around 52–58 cm but weighing a muscular 30–38 kg, it is a compact, broad-headed dog of considerable strength, historically used for guarding and, in earlier times, for bull-baiting — the name itself translates roughly as 'bull dog'.
Despite its formidable build the Ca de Bou is typically calm, confident and devoted to its family. It is a serious guarding breed, however, with the strength and reactivity to match, and it is firmly a dog for experienced, capable owners. It is rare in the UK and is not separately recognised by The Kennel Club.
Good to know — a Ca de Bou needs plenty of space and best for experienced owners. Every dog is an individual, so meet a few and chat to a good breeder or rescue before deciding.

History & origins
The breed developed on Majorca, where molosser-type dogs were used for guarding property and livestock and, during a particular era, in bull-baiting before such practices were banned. Its ancestry reflects a mix of native guarding dogs and imported mastiff and bulldog types brought to the island through its trading history.
The Ca de Bou is recognised by Spain's national kennel club and by the FCI within its molossoid grouping. The breed went through a period of low numbers and has been carefully rebuilt by dedicated breeders. It remains uncommon, and large-scale health data is limited.
Temperament & family fit
Within the home the Ca de Bou is generally calm, steady and deeply loyal, forming a strong bond with its family and often showing real gentleness towards the people it trusts. It is confident and self-assured rather than nervous, and a well-bred, well-raised individual is typically composed and even-tempered.
Its guarding heritage is never far from the surface, though. It is watchful and can be protective and dog-reactive without careful socialisation and handling. This is a strong, powerful animal that takes situations seriously, so it requires an owner who can provide consistent leadership and who fully understands the responsibilities of a molosser breed.
- Families with older, respectful children
- Owners ready for consistent training
- Active homes with plenty of space
Training & intelligence
The Ca de Bou is intelligent and willing to please its handler, but its strength and guarding instincts mean training and socialisation must be thorough and ongoing. Early, positive exposure to a wide range of people, dogs and situations is essential to produce a stable, manageable adult. Reward-based methods build the trust and cooperation this breed offers in return.
Firm, calm and consistent handling matters more than force; harsh treatment can damage the relationship and provoke problems in a dog this powerful. Reliable obedience, good lead manners and controlled behaviour around other dogs should be priorities from puppyhood.
- Start socialisation & handling early
- Reward-based methods only — no harsh corrections
- Keep sessions short, calm and consistent
Exercise needs
A healthy adult Ca de Bou typically needs around an hour a day (roughly 60–80 minutes), split across walks, play and a little training. A good sniffy walk, some play and a little training usually keeps them content. Puppies, seniors and dogs with health conditions need adjusted amounts — check with your vet.
Grooming & coat
Grooming is straightforward. The short, smooth coat needs only a weekly brush to remove loose hair and keep it healthy, with moderate shedding. Pay attention to any facial skin folds, keeping them clean and dry, and maintain routine ear, nail and dental care. Overall this is a low-maintenance breed in terms of coat.
- Brush occasionally to remove loose hair
- Bathe every few weeks or as needed
- Check ears, nails and teeth weekly
Feeding considerations
Feed a complete diet suited to a large, muscular dog, divided into two meals a day to support steady digestion. Keep the Ca de Bou lean and well-muscled rather than allowing it to carry excess weight, which would strain its joints and heart. As with all heavy, broad-chested breeds, avoid vigorous activity right around mealtimes and ensure plenty of fresh water.
Ca de Bou health & costs
Before bringing a Ca de Bou home it pays to budget for the whole picture — food, insurance, grooming and routine vet care all add up. The figures below are typical UK estimates for a healthy adult; your real costs vary with where you live, your dog's health and the cover you choose.
Food
£600–850 / year
Complete food sized to weight & life stage
Insurance
£35–62 / month
Lifetime cover — varies by age, breed & area
Grooming
£0–60 / year
Mostly DIY at home
Routine vet care
£200–450 / year
Vaccines, flea/worm, annual check
As a relatively rare molosser breed, the Ca de Bou has limited published health data, and a lifespan of around 10–12 years is typical for a dog of its type and size. Prospective owners should ask breeders directly about the health, screening and longevity of their lines.
The main concerns mirror those of other heavy, powerful breeds: joint problems such as hip and elbow dysplasia, and the potential for breathing difficulty and heat sensitivity associated with its broad, somewhat shortened muzzle. Bloat is also a consideration in deep-chested dogs.
Common health conditions to be aware of
- Hip dysplasia — common in heavy molosser breeds; ask for hip scores on the parents.
- Elbow dysplasia — a developmental joint condition causing forelimb lameness in large dogs.
- Brachycephalic-related breathing difficulty — the broad, shortened muzzle can predispose to reduced heat tolerance and breathing issues; avoid over-exertion in the heat.
- Gastric dilatation-volvulus (bloat) — a life-threatening stomach twist in deep-chested dogs; feed smaller meals and know the signs.
- Skin-fold dermatitis — facial folds can become irritated or infected if not kept clean and dry.
- Osteoarthritis — degenerative joint disease that heavy dogs are prone to with age.
These reflect typical, size- and coat-related risks for dogs like the Ca de Bou; individual breeds carry their own predispositions. Always buy from health-tested parents and speak to your vet — this isn't a diagnosis.

Bringing home a Ca de Bou puppy
Puppies need controlled exercise (a rough guide is five minutes per month of age, twice a day) to protect growing joints, little-and-often meals of a complete puppy food, early socialisation, and a calm routine for toilet training and sleep. Book first vaccinations, microchipping and a vet check early.
New puppy checklist →Caring for a senior Ca de Bou
As they age, watch weight, joints and teeth, switch to a senior diet if your vet advises, keep exercise gentle but regular, and consider orthopaedic bedding and ramps. Twice-yearly vet checks help catch issues early — larger breeds age sooner, so start senior care from around 6–7 years.

Frequently asked questions
How long do Ca de Bou dogs live?
The Ca de Bou typically lives around 10 to 12 years, which is fairly normal for a powerful molosser of its size. As a rare breed there is limited published longevity data, so ask breeders directly about the health and lifespan of their own lines, and support a long life with a lean weight, sensible exercise and regular veterinary care.
How big does a Ca de Bou get?
The Ca de Bou is a compact but very powerful molosser. Adults usually stand around 52 to 58 cm at the shoulder yet weigh a muscular 30 to 38 kg, thanks to a broad head, heavy bone and a thickset, athletic frame. It is best thought of as a medium-height dog with the substance and strength of a much larger breed.
What is the temperament of a Ca de Bou?
Within the home the Ca de Bou is usually calm, confident and deeply devoted, often gentle with the people it trusts. It is a serious guarding breed, however, and is watchful and can be protective or dog-reactive without careful socialisation. It is composed rather than nervous, but its strength and guarding drive mean it suits experienced, capable owners only.
Do Ca de Bou dogs shed much and need a lot of grooming?
Grooming is straightforward. The short, smooth coat sheds moderately and needs only a weekly brush to remove loose hair and keep it healthy. Pay attention to any facial skin folds, keeping them clean and dry, and maintain routine ear, nail and dental care. Overall this is a low-maintenance breed where coat care is concerned.
How much exercise does a Ca de Bou need?
The Ca de Bou has moderate exercise needs and is powerful rather than hyperactive. Daily walks plus some free running in secure areas keep it fit and content; it does not demand the relentless activity of a herding or sled dog. With its broad, somewhat shortened muzzle it should not be over-exerted in hot weather, and a securely fenced garden is important.
Is the Ca de Bou good with children and other dogs?
A well-bred, well-socialised Ca de Bou can be calm and gentle with its own family, but as a serious guarding molosser it can be wary or reactive towards unfamiliar dogs without careful socialisation. Any interaction between a powerful dog and young children should always be supervised. This is firmly a breed for experienced owners who understand molosser responsibilities.
What health problems is the Ca de Bou prone to?
As a rare breed, published health data is limited. The main concerns mirror other heavy, powerful dogs: joint problems such as hip and elbow dysplasia, possible breathing difficulty and heat sensitivity linked to its broad muzzle, and bloat in deep-chested individuals. Ask breeders about health screening and longevity in their lines, and keep your dog lean. Your vet can advise on preventive care.
Is a Ca de Bou suitable for first-time owners?
No. The Ca de Bou is a strong, protective guarding breed that takes situations seriously and needs consistent leadership, thorough socialisation and secure boundaries. It is not suited to novices, to busy households with constant visitors, or to small flats. In knowledgeable, experienced hands it makes a loyal, steady and dependable guardian, but it is a significant responsibility.
Are Ca de Bous good with children?
Fine with sensible, older children. As a general guide, Ca de Bous tend to be fine with sensible, older children. Whatever the breed, always supervise dogs and young children and teach kids to interact gently.
How much exercise does a Ca de Bou need?
As a healthy adult, a typical Ca de Bou needs around an hour of exercise a day (60–80 minutes), split across walks plus play. A good sniffy walk plus some play and training usually keeps them happy. Puppies, seniors and dogs with health conditions need less — ask your vet.
Do Ca de Bous shed a lot?
Moderate shedding. Coat upkeep is wash-and-go — a quick brush now and then is usually enough.
Are Ca de Bous easy to train and good for first-time owners?
Best for experienced owners. Ca de Bous are best for owners ready to commit to consistent training and plenty of activity. Reward-based training and early socialisation help any dog.
Do Ca de Bous bark a lot?
Quiet. They are usually fairly easy-going about barking, though any dog will bark if bored or under-exercised.
Are Ca de Bous good with other dogs?
Can be selective with other dogs. Early, positive socialisation with other dogs from a young age makes a big difference.
Do Ca de Bous suit flats or smaller homes?
Needs plenty of space. A Ca de Bou really needs plenty of space and a lot of daily activity — not ideal for a small flat.
