Saint Berdoodle
A giant, good-natured cross of the patient St. Bernard and the intelligent Poodle. Gentle and devoted with families, but a very large dog needing space, grooming and the usual giant-breed health awareness.
Saint Berdoodle scorecard
Overview
The Saint Berdoodle, sometimes spelled St. Berdoodle or Saint Berpoo, is a large-to-giant designer crossbreed produced by mating a St. Bernard with a Poodle (usually a Standard Poodle). The cross aims to pair the patient, good-natured temperament of the St. Bernard with the intelligence and lower-shedding coat of the Poodle. Most Saint Berdoodles are big, sturdy dogs with thick, often wavy coats, frequently in the white-and-tan or brown patterns of the St. Bernard.
The Saint Berdoodle is not a recognised breed. Neither The Kennel Club nor the FCI registers it, there is no breed standard and no formal registry, so 'type' is not guaranteed. Because the parent breeds differ greatly and giant size adds welfare considerations, individuals vary widely in size, coat, drool and temperament. Taking one on is a major commitment of space, time and money, and prospective owners should study both parent breeds carefully first.
Good to know — a Saint Berdoodle needs plenty of space and manageable for committed beginners. Every dog is an individual, so meet a few and chat to a good breeder or rescue before deciding.

History & origins
The Saint Berdoodle is a modern designer cross with no long history of its own, part of the broad expansion of Poodle crosses that followed the Labradoodle's emergence in the late 1980s. Deliberate St. Bernard × Poodle litters have become more common since the 2000s, generally marketed as gentle giants with a more allergy-friendly coat.
Its character comes from its parents. The St. Bernard is a Kennel Club–recognised working breed from the Swiss Alps, historically associated with the hospice of the Great St Bernard Pass and famed as a powerful mountain-rescue and companion dog of legendary gentleness. The Poodle began as a German water-retrieving gundog and is one of the most intelligent and trainable breeds. Crossing a calm, devoted giant with a clever water dog usually yields an affectionate, fairly placid but very large dog — though the cross has no standardised lineage of its own.
Temperament & family fit
Saint Berdoodles are usually gentle, patient and devoted, often excellent with children and content as calm family companions. The St. Bernard is renowned for its mellow, tolerant nature, and the Poodle adds friendliness and intelligence, so most Saint Berdoodles are affectionate, sociable dogs that enjoy being part of the family and tend to be relaxed at home.
Temperament still varies in any crossbreed. The St. Bernard side leans placid and a little stubborn, while the Poodle side is more alert, sensitive and active; a given dog may favour either. What is generally consistent is a strong bond with the family and a wish to be included. Early socialisation is especially important in a dog of this size, so that its calm, confident side is reliably brought out.
- Families with children of all ages
- Owners ready for consistent training
- Active homes with plenty of space
Training & intelligence
Saint Berdoodles are typically willing learners, taking biddability from both parents, but training a giant dog is about safety as much as obedience. Good manners, polite greetings and reliable basics must be taught early, while the dog is still manageable in size, because a fully grown Saint Berdoodle is far too large and strong to muscle into compliance later. Positive, reward-based training suits these sensitive dogs best.
Lead manners and recall deserve early, consistent work, and jumping up should be discouraged from the start given the eventual size of the dog. The Poodle influence usually makes them enjoy learning, so ongoing mental stimulation is valuable — but, as with all large, growing breeds, training should avoid excessive impact and repetitive jumping while the joints mature.
- Start socialisation & handling early
- Reward-based methods only — no harsh corrections
- Keep sessions short, calm and consistent
Exercise needs
A healthy adult Saint Berdoodle 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
Coat type varies from wavy and Poodle-like to thicker and more St. Bernard, but either way it is usually dense and prone to matting, needing brushing several times a week and professional grooming every couple of months. 'Low-shedding' and 'hypoallergenic' are marketing terms rather than guarantees, and coat behaviour differs between individuals. Many Saint Berdoodles drool to some extent, inherited from the St. Bernard, and their ears should be checked and cleaned regularly. The size and coat together make grooming a substantial ongoing commitment.
- Brush several times a week
- Bathe every few weeks or as needed
- Check ears, nails and teeth weekly
Feeding a Saint Berdoodle
Feed a complete diet formulated for large or giant breeds, using large-breed puppy food during growth to encourage slow, controlled development and reduce strain on forming joints. Keep the dog lean, as excess weight is particularly harmful to giant-breed joints and overall health. Because deep-chested giants are at risk of bloat (gastric dilatation-volvulus), divide the daily ration into two or more meals, consider a slow feeder and avoid strenuous activity around mealtimes. Feeding a dog of this size is a meaningful ongoing cost to budget for.
A giant breed
An adult Saint Berdoodle typically weighs 32–80 kg, so a healthy Saint Berdoodle eats a lot, and the sack size matters as much as the recipe compared with other breeds. Every feeding guide on a bag is written per kilo of body weight, not per breed — start there, then adjust to the dog in front of you.
Life stage
A giant breed is usually done growing at 18–24 months, which is roughly when a puppy food has finished its job. With a typical lifespan of 8–12 years, there is a long adult stretch in the middle; switch to a senior food when your vet thinks it is worth it rather than on a birthday.
Joint support is worth looking for
Their size and frame put more load through the joints than a smaller dog carries, so a food with joint support on the label is worth reading for — and keeping them lean does more for their joints than any supplement.
Weight matters more than usual here
A long back or a heavy frame makes every extra kilo count twice. Weigh portions rather than eyeballing a scoop, and reduce the food rather than the walks if the waist starts to disappear.
How much should a Saint Berdoodle weigh?
Adult 32–80 kgfully grown at 18–24 months
| Age | Stage | Typical weight | Of adult size |
|---|---|---|---|
| 8 weeks | Just home | 2.8–7 kg | 9% |
| 3 months | Young puppy | 4.6–11.4 kg | 14% |
| 6 months | Growing fast | 9.1–22.9 kg | 29% |
| 12 months | Adolescent | 18.3–45.7 kg | 57% |
| 18–24 months | Fully grown | 32–80 kg | 100% |
A guide, from the same rule of thumb our puppy growth predictor uses — each age is that share of the way to maturity for a giant breed. Puppies grow fastest early, so a real puppy usually sits a little above the middle rows. Weigh yours and ask your vet if the number worries you.

As a giant crossbreed, the Saint Berdoodle can inherit health problems from both parent breeds, and giant size carries inherent risks including a shorter average lifespan. Crossbreeding does not remove inherited disease risk, so the parent dogs should be health-tested and the results made available to buyers.
From the St. Bernard side, concerns include hip and elbow dysplasia, heart disease (such as dilated cardiomyopathy), entropion and other eyelid problems, osteosarcoma (bone cancer) and bloat. From the Poodle side, concerns include hip dysplasia, progressive retinal atrophy and other eye conditions, epilepsy and bloat in Standards. Appropriate screening — hip and elbow scoring, eye testing, cardiac assessment and relevant DNA tests — should be performed on the parents.
Common health conditions to be aware of
- Hip and elbow dysplasia — joint malformations common in giant breeds, leading to pain and arthritis; both parents should be hip and elbow scored.
- Bloat / gastric dilatation-volvulus (GDV) — a sudden, life-threatening twisting of the stomach that giant deep-chested dogs are highly prone to; an emergency needing immediate veterinary treatment.
- Entropion / ectropion — inherited eyelid defects common in St. Bernards where the lid rolls inward or outward, irritating the eye and sometimes needing surgery.
- Dilated cardiomyopathy (DCM) — a heart-muscle disease recognised in St. Bernards; cardiac screening of breeding stock is advisable.
- Osteosarcoma — an aggressive bone cancer to which large and giant breeds are predisposed, more common in older dogs.
- Heat intolerance — the heavy coat and large mass mean Saint Berdoodles overheat easily and need cool conditions, shade and fresh water.
These reflect typical, size- and coat-related risks for dogs like the Saint Berdoodle; 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 Saint Berdoodle 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 Saint Berdoodle
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 big is a full-grown Saint Berdoodle?
The Saint Berdoodle is a large-to-giant crossbreed, typically standing around 60–76 cm at the shoulder and weighing roughly 32–80 kg fully grown. Size varies widely because it crosses a giant St. Bernard with a Poodle and there is no breed standard, so individuals differ considerably depending on which parent they most resemble.
What is the life expectancy of a Saint Berdoodle?
Saint Berdoodles generally live around 8–12 years. As with all giant breeds, their average lifespan is shorter than that of smaller dogs, which prospective owners should be prepared for. Keeping the dog lean, feeding an appropriate large or giant-breed diet and choosing health-tested parents all help support a healthier, fuller life.
Is there such a thing as a mini Saint Berdoodle?
Some breeders cross a St. Bernard with a smaller Poodle to produce a more compact dog often marketed as a 'mini' Saint Berdoodle. However, the Saint Berdoodle is not a recognised breed and there is no breed standard or registry, so size is never guaranteed. Even smaller examples can still grow into substantial dogs, so research the actual parents involved.
Do Saint Berdoodles shed or drool?
Coat type varies from wavy and Poodle-like to thicker and more St. Bernard, so shedding differs between individuals; 'low-shedding' and 'hypoallergenic' are marketing terms, not guarantees. Many Saint Berdoodles also drool to some extent, inherited from the St. Bernard side. Expect a dense, mat-prone coat needing regular brushing and professional grooming.
Are Saint Berdoodles good with children?
Yes, they are usually excellent family dogs. The St. Bernard is renowned for its mellow, tolerant nature and the Poodle adds friendliness and intelligence, so most Saint Berdoodles are gentle, patient and affectionate, and content as calm companions. Early socialisation matters in a dog this size to reliably bring out its confident, easy-going side.
How much exercise does a Saint Berdoodle need?
They need regular but moderate exercise — a couple of good daily walks plus play and enrichment — rather than intense activity. Growing puppies must not be over-exercised, as too much jumping or running on hard surfaces can damage developing giant-breed joints. As heavy-coated dogs prone to overheating, exercise is best timed for cooler parts of the day in warm weather.
What health issues affect Saint Berdoodles?
Being a giant crossbreed, they can inherit problems from both parents. St. Bernard concerns include hip and elbow dysplasia, heart disease such as dilated cardiomyopathy, entropion and other eyelid problems, bone cancer and bloat; Poodle concerns include hip dysplasia, progressive retinal atrophy, eye conditions and epilepsy. Always ask to see the parents' health-test results.
Why are Saint Berdoodles prone to bloat, and how can it be reduced?
Like other deep-chested giants, Saint Berdoodles are at risk of bloat (gastric dilatation-volvulus), a serious, sometimes fatal condition. Sensible precautions include dividing the daily food into two or more meals, using a slow feeder and avoiding strenuous activity around mealtimes. If your dog shows a swollen abdomen, retching or distress, seek emergency veterinary help immediately.
Are Saint Berdoodles good with children?
Excellent with children of all ages. As a general guide, Saint Berdoodles tend to be patient and tolerant. Whatever the breed, always supervise dogs and young children and teach kids to interact gently.
How much exercise does a Saint Berdoodle need?
As a healthy adult, a typical Saint Berdoodle 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 Saint Berdoodles shed a lot?
Low shedding. Coat upkeep is high upkeep — plan on frequent brushing and regular trips to a groomer.
Are Saint Berdoodles easy to train and good for first-time owners?
Manageable for committed beginners. Saint Berdoodles are best for owners ready to commit to consistent training and plenty of activity. Reward-based training and early socialisation help any dog.
Do Saint Berdoodles bark a lot?
Quiet. They are usually fairly easy-going about barking, though any dog will bark if bored or under-exercised.
Are Saint Berdoodles good with other dogs?
Sociable with other dogs. Early, positive socialisation with other dogs from a young age makes a big difference.
Do Saint Berdoodles suit flats or smaller homes?
Needs plenty of space. A Saint Berdoodle really needs plenty of space and a lot of daily activity — not ideal for a small flat.
