Saarloos Wolfdog
A Dutch breed created by crossing a German Shepherd with a wolf, retaining a wolf-like look and nature. Reserved, cautious and strongly bonded to its pack, it is shy of strangers and needs a very experienced, patient owner.
Saarloos Wolfdog scorecard
Overview
The Saarloos Wolfdog is a large, wolf-like breed standing roughly 60–75 cm tall and weighing around 30–41 kg, created in the Netherlands by deliberately crossing a German Shepherd with a wolf. The result is an athletic, powerful dog that retains much of the appearance and many of the instincts of its wild ancestor, with a reserved, cautious nature quite unlike that of an ordinary domestic dog.
This is not a pet for most households. The Saarloos is deeply loyal to its own pack but typically shy of strangers, sensitive to its environment, and demanding of expert handling and extensive socialisation. It is recognised by the FCI but is not a breed of The Kennel Club, and prospective owners in the UK should research thoroughly and seek experienced mentorship before considering one.
Good to know — a Saarloos Wolfdog 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 was developed from the 1930s by Dutch breeder Leendert Saarloos, who crossed a male German Shepherd with a female European wolf in an attempt to create a hardier, more natural working dog. The early generations retained strong wolf characteristics, and over subsequent decades the breeding programme stabilised the type, with the breed officially recognised in the Netherlands in 1975 and named in honour of its creator.
The Saarloos Wolfdog gained FCI recognition in 1981. It remains an uncommon breed, kept by enthusiasts who value its wolf-like appearance and character, and its history as a recent wolf hybrid is central to understanding its temperament.
Temperament & family fit
Saarloos Wolfdogs are reserved, cautious and strongly pack-oriented, forming powerful bonds with their family while remaining wary, shy or avoidant towards strangers. Far from being aggressive, the typical Saarloos is more likely to retreat from unfamiliar people or situations, and the breed is known for being sensitive, observant and quiet, rarely barking. It communicates instead through body language and behaviour.
This flighty, wolf-like nature means the breed needs a calm, predictable environment and a great deal of patient socialisation from puppyhood. It is generally not suited to homes with very young children, frequent visitors or busy lifestyles, and its instincts make it a poor choice for owners expecting a conventional, biddable companion.
- Families with older, respectful children
- Owners ready for consistent training
- Active homes with plenty of space
Training & intelligence
Training a Saarloos calls for exceptional patience, consistency and a deep understanding of canine body language. The breed is intelligent but independent and easily startled, and it will shut down or withdraw under pressure, so only gentle, reward-based, trust-building methods are appropriate. Building confidence and a reliable bond matters far more than obedience drills.
Reliable off-lead recall is very difficult to achieve given the breed's caution and strong instincts, and most owners keep these dogs on lead or within secure areas. This is firmly a breed for highly experienced owners, ideally those with specific guidance from established Saarloos keepers.
- Start socialisation & handling early
- Reward-based methods only — no harsh corrections
- Channel energy into training games & enrichment
Exercise needs
A healthy adult Saarloos Wolfdog typically needs 90 minutes to 2 hours a day (roughly 90–120 minutes), split across walks, play and a little training. Higher-energy dogs also need their brains tired — sniffy walks, training games and puzzle feeding go a long way. Puppies, seniors and dogs with health conditions need adjusted amounts — check with your vet.
Grooming & coat
The dense, weatherproof double coat is fairly low-maintenance, requiring weekly brushing for most of the year. During its heavy seasonal moults the dog sheds profusely, and daily brushing helps manage the loose hair at these times. Baths are rarely needed, as the coat naturally repels dirt; routine nail, ear and dental care complete the grooming routine.
- Brush several times a week
- Bathe every few weeks or as needed
- Check ears, nails and teeth weekly
Feeding a Saarloos Wolfdog
Feed a complete, good-quality diet appropriate to a large, active dog, with portions matched to the individual's age and energy output. As with any large breed, careful feeding during growth supports healthy joint development, and adults should be kept lean to protect their joints. Divide the daily amount into measured meals, provide fresh water at all times, and follow veterinary guidance.
A large breed
An adult Saarloos Wolfdog typically weighs 30–41 kg, so a healthy Saarloos Wolfdog eats a fair amount 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 large breed is usually done growing at 15–18 months, which is roughly when a puppy food has finished its job. With a typical lifespan of 10–12 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.
A high-energy dog eats like one
Saarloos Wolfdogs sit at the top end for energy, and a dog working through an hour and a half of real exercise a day burns through the feeding guide faster than a dog on a short stroll. Feed to the dog's condition, not to the middle of the range on the bag.
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 Saarloos Wolfdog weigh?
Adult 30–41 kgfully grown at 15–18 months
| Age | Stage | Typical weight | Of adult size |
|---|---|---|---|
| 8 weeks | Just home | 3.4–4.7 kg | 11% |
| 3 months | Young puppy | 5.6–7.6 kg | 19% |
| 6 months | Growing fast | 11.1–15.2 kg | 37% |
| 12 months | Adolescent | 22.3–30.5 kg | 74% |
| 15–18 months | Fully grown | 30–41 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 large 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.

The Saarloos Wolfdog is generally a hardy breed with a typical lifespan of around 10–12 years, benefiting from its athletic build and relatively natural conformation. As a large breed, it is subject to the orthopaedic conditions common to dogs of its size.
Because the breed is rare, breed-specific health information is limited compared with popular breeds, and its recent wolf ancestry adds further uncertainty. Responsible breeders screen for hereditary problems where schemes exist and prioritise sound temperament; prospective owners should ask about the health of the parents and the breeding line.
Common health conditions to be aware of
- Hip dysplasia — a hereditary joint malformation common in large breeds that can lead to pain and arthritis; breeding dogs should be hip-scored.
- Elbow dysplasia — developmental elbow disease causing lameness in larger breeds, screened by hip and elbow schemes.
- Degenerative myelopathy — a progressive spinal cord disease reported in the breed; DNA testing is available to identify carriers.
- Pituitary dwarfism — a genetic growth-hormone disorder associated with related shepherd-type lines; DNA testing helps responsible breeders avoid it.
- Anxiety and stress-related behaviour — the breed's sensitive, flighty nature means poor socialisation can cause significant fear-based problems.
- Limited breed-specific data — its rarity means inherited-disease information is less complete than for common breeds.
These reflect typical, size- and coat-related risks for dogs like the Saarloos Wolfdog; 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 Saarloos Wolfdog 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 Saarloos Wolfdog
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
What is a Saarloos Wolfdog?
It is a large, wolf-like breed created in the Netherlands by deliberately crossing a German Shepherd with a wolf. The result is an athletic, powerful dog that retains much of the appearance and many of the instincts of its wild ancestor, with a reserved, cautious nature quite unlike that of an ordinary domestic dog. It is recognised by the FCI but not by The Kennel Club.
How big is a Saarloos Wolfdog?
It is a large breed standing roughly 60–75 cm tall and weighing around 30–41 kg, with an athletic, powerful build and a dense, weatherproof double coat. Its size and strength, combined with strong wolf-like instincts, mean it demands expert handling and is not a suitable pet for most households.
Are Saarloos Wolfdogs aggressive?
Far from it. The typical Saarloos is reserved, cautious and shy rather than aggressive, and is more likely to retreat from unfamiliar people or situations than to confront them. It is sensitive, observant and quiet, rarely barking, communicating instead through body language. This flighty nature needs a calm, predictable environment and patient socialisation.
What is the difference between a Saarloos Wolfdog and a Czechoslovakian Wolfdog?
Both are wolf-like breeds created by crossing German Shepherds with wolves, but they have separate origins. The Saarloos was developed in the Netherlands and is known for being especially reserved and flighty. They differ in their founding lines and breed standards. Either way, both are demanding breeds for highly experienced owners only.
Are Saarloos Wolfdogs good family pets?
This is not a pet for most households. The Saarloos is deeply loyal to its own pack but typically shy of strangers and sensitive to its environment. It is generally not suited to homes with very young children, frequent visitors or busy lifestyles, and is a poor choice for anyone expecting a conventional, biddable companion.
Can you train a Saarloos Wolfdog and let it off-lead?
Training calls for exceptional patience, consistency and a deep understanding of canine body language. The breed is intelligent but independent and easily startled, and will shut down under pressure, so only gentle, trust-building methods work. Reliable off-lead recall is very difficult given its caution and strong instincts, so most are kept on lead or in secure areas.
How much exercise and grooming does a Saarloos Wolfdog need?
It is an athletic, stamina-rich breed needing plenty of daily exercise in a calm, secure setting, with mental enrichment as important as physical activity. The dense double coat is fairly low-maintenance, needing weekly brushing for most of the year, with daily brushing during heavy seasonal moults. Baths are rarely needed as the coat repels dirt.
What kind of home does a Saarloos Wolfdog need?
It needs space, a quiet and predictable home, and an experienced owner devoted to its considerable socialisation and welfare needs. A secure, high-fenced garden is essential. It is unsuited to flats, busy households or homes with very young children. Owners should be prepared for a sensitive, reserved dog that may never be comfortable with strangers.
Are Saarloos Wolfdogs good with children?
Best with older, calm children. As a general guide, Saarloos Wolfdogs tend to be better suited to homes with older children or no young children. Whatever the breed, always supervise dogs and young children and teach kids to interact gently.
How much exercise does a Saarloos Wolfdog need?
As a healthy adult, a typical Saarloos Wolfdog needs 90 minutes to 2 hours of exercise a day (90–120 minutes), split across walks plus play. Higher-energy dogs also need mental stimulation — sniffing, training games and puzzle feeders — to stay settled. Puppies, seniors and dogs with health conditions need less — ask your vet.
Do Saarloos Wolfdogs shed a lot?
High shedding. Coat upkeep is regular brushing — brush regularly to keep the coat in good condition.
Are Saarloos Wolfdogs easy to train and good for first-time owners?
Best for experienced owners. Saarloos Wolfdogs are best for owners ready to commit to consistent training and plenty of activity. Reward-based training and early socialisation help any dog.
Do Saarloos Wolfdogs bark a lot?
Quiet. They are usually fairly easy-going about barking, though any dog will bark if bored or under-exercised.
Are Saarloos Wolfdogs good with other dogs?
Generally fine with other dogs. Early, positive socialisation with other dogs from a young age makes a big difference.
Do Saarloos Wolfdogs suit flats or smaller homes?
Needs plenty of space. A Saarloos Wolfdog really needs plenty of space and a lot of daily activity — not ideal for a small flat.
