The Biewer Terrier is a small, tri-colored toy companion dog with a long, silky, low-shedding coat that needs frequent grooming. Cheerful, playful, and people-oriented, it suits apartment living, needs moderate exercise, gentle training, and can live into its mid teens with good care.

## Quick Facts

- Dutch breed developed by crossing a German Shepherd with a European wolf, creating a very natural, wolf-like companion.
- Extremely sensitive and reserved with strangers, yet deeply loyal and attached to “their” people.
- Not a beginner’s dog and generally unsuited to hectic city life or small apartments.
- Needs a lot of secure outdoor space, mental stimulation, and patient, positive training to thrive.
- Best with experienced owners who appreciate independent, primitive-type dogs and can commit to careful socialisation.

## Appearance & Coat

The Saarloos Wolfdog is a striking, athletic dog that immediately catches the eye with its clear wolf-like expression and natural elegance. At first glance you see a balanced, lightly built animal, never bulky or exaggerated. The body is slightly longer than it is tall, with a straight, strong back and a deep but not overly broad chest. Everything about the Saarloos Wolfdog suggests endurance, agility, and the ability to move over long distances without tiring.

Males are usually noticeably larger and more powerful than females. While exact height and weight can vary, you can expect a tall, medium to large sized dog. Females often appear a little more refined and feminine in head and body. The head itself is wedge-shaped, with a slightly domed skull, a gently defined stop, and a relatively long muzzle. The eyes are almond-shaped, slightly oblique, and often yellow or amber, which adds strongly to the wolf-like expression. Ears are medium-sized, triangular, and carried erect, set fairly high on the head but not overly large.

The Saarloos Wolfdog coat is double layered and weather resistant. The outer coat is straight, close lying, and fairly harsh to the touch. Underneath there is a thick, soft undercoat that adjusts to the climate. In winter, this undercoat becomes very dense to protect the dog from cold and damp, while in summer it becomes lighter and sparser. Around the neck, shoulders, and back of the thighs you can often see more abundant hair, creating a slight ruff and “pants.”

Common colours include:

- Wolf grey  
- Brown shaded sable  
- Cream or light, diluted shades of these colours  

White markings may appear but should not dominate. The colour is often shaded, with darker hairs overlaying lighter ones, which creates a natural, wild look similar to that of a wolf. The nose is strongly pigmented and matches the coat type, usually black or brown.

Coat care is fairly straightforward but requires routine. The Saarloos Wolfdog sheds heavily during seasonal coat changes, often twice a year. During these periods, daily brushing with a slicker brush or pin brush helps remove loose undercoat and keeps hair from covering your furniture. Outside shedding seasons, a thorough brushing once or twice a week is usually enough. Bathing should be rare and only when necessary because frequent shampooing can strip the natural oils that help waterproof the coat and protect the skin. Most owners find that a simple rinse with clean water after a muddy walk is usually enough.

Regular checks of ears, teeth, and nails are important. The erect ears allow good airflow but still need occasional inspection and gentle cleaning. Nails should be kept at a reasonable length to support sound movement, especially if the dog does not naturally wear them down on rough surfaces. Overall, maintenance is manageable for a large dog, but you must be prepared for periods of very heavy shedding.

## Temperament & Personality

Living with a Saarloos Wolfdog is very different from living with many typical companion breeds. This is a sensitive, intelligent, and independent dog that still carries strong traits from its wolf ancestry. The typical Saarloos Wolfdog is reserved, watchful, and cautious with strangers, but not naturally aggressive. Instead of confronting something that worries them, many will choose to keep their distance or retreat. This tendency to avoid conflict is an important part of the breed’s character and must be understood and respected.

With their own family, Saarloos Wolfdogs are often deeply attached, gentle, and sometimes surprisingly affectionate in their own quiet way. They may follow their person from room to room, lie at their feet, or rest where they can observe everyone. Many are very attuned to human emotions and react strongly to tension, raised voices, or chaotic environments. They tend to feel safest in calm, predictable households with clear routines.

Around children, a well-bred, well-socialised Saarloos Wolfdog can be kind and tolerant, but this is not a rough-and-tumble, endlessly patient “nanny” dog. They are usually better with older, respectful children who understand how to behave gently with animals. Fast, noisy play or sudden hugs can easily overwhelm them. Careful supervision is essential, and children must be taught to give the dog space when it chooses to walk away.

With other dogs, the breed often does well, particularly if raised with them from a young age. Saarloos Wolfdogs can enjoy the company of their own kind and other stable, polite dogs. They tend to be subtle communicators, using body language and avoidance rather than open conflict. However, mismatches can happen, especially with pushy or very dominant dogs that do not read their signals. Introducing them slowly and thoughtfully is important. With smaller pets, such as cats or rabbits, their natural prey drive can be an issue. Some individuals coexist peacefully with cats they grow up with, while others may always see small animals as something to chase. Prospective owners should think carefully if they have free roaming small pets.

Common challenges include:

- Shyness or strong reserve with unfamiliar people and environments  
- Tendency to flee or avoid rather than confront when scared  
- Strong independence, which can look like stubbornness in training  
- Sensitivity to punishment, harsh voices, and chaotic households  

A Saarloos Wolfdog is not the ideal choice for someone who wants a highly social, outgoing dog that loves every stranger. Nor is it a good fit for households that expect immediate obedience or constant cuddling. However, for people who appreciate a thoughtful, observant, almost wild-spirited companion, the Saarloos Wolfdog can be immensely rewarding. They need trust, time, and a sense of safety, and in return they form deep, lasting bonds.

## Training & Exercise

Training a Saarloos Wolfdog requires patience, consistency, and a particular mindset. This is not a dog that will blindly follow commands simply to please. Instead, they tend to think for themselves and often ask, “Why should I do this?” before responding. They are highly intelligent and learn quickly, but motivation must be handled carefully.

Positive reinforcement is vital. Food treats, gentle praise, and the opportunity to move or explore are all powerful rewards for this breed. Short, varied training sessions work far better than long, repetitive drills. Many owners find that strict, obedience-focused methods that rely on physical corrections or raised voices quickly damage trust. The Saarloos Wolfdog is very sensitive to tension and unfairness. Once trust is lost, it can be difficult to regain.

A good training approach includes:

- Early, thoughtful socialisation to people, places, surfaces, and sounds  
- Reward-based training methods using treats, toys, or access to interesting environments  
- Clear, simple cues and consistent routines  
- Plenty of time to observe and process new experiences rather than being pushed  

Socialisation must be handled especially carefully. For a Saarloos Wolfdog puppy, quality is more important than quantity. Overwhelming a young dog with crowded places or forcing interactions with strangers can backfire and increase insecurity. Instead, allow the puppy to watch from a safe distance, then choose to approach if it feels confident. Calm, dog-savvy visitors who ignore the puppy until it decides to say hello are often very helpful.

Exercise needs are significant. This breed was designed for stamina more than speed. Daily long walks and opportunities to trot steadily at your side will help keep them balanced and relaxed. A fit adult Saarloos Wolfdog will usually enjoy:

- One or two long walks or hikes every day  
- Time to explore natural areas on a long line or in a secure field  
- Scent-based games, tracking, or searching for hidden items  
- Activities that tap into their curiosity, such as puzzle feeders or scent trails  

Although energetic, they are not usually hyperactive in the home if properly exercised. They are often calm and content to rest after their physical and mental needs are met. However, without enough outlets, they may become restless, anxious, or destructive. Secure fencing is essential, as many Saarloos Wolfdogs are talented at finding weak points, squeezing through gaps, or climbing if they feel like escaping.

Some individuals enjoy structured activities like mantrailing, tracking, or canicross. Traditional precision obedience or protection sports are usually not a good match due to their independent nature and soft character. They respond far better to cooperative activities that allow them to use their senses and natural talents, rather than tasks requiring intense handler focus and high pressure.

In summary, training a Saarloos Wolfdog is about building a respectful partnership. If you approach them as a teammate rather than a servant, and if you provide enough physical exercise and mental stimulation, you will discover an exceptionally intelligent and responsive companion.

## Health

The Saarloos Wolfdog is generally a robust and hardy breed, but like all dogs it has some health concerns that responsible owners and breeders must take seriously. Because the breed was founded from a limited number of dogs, including a single wolf and a few German Shepherds, managing genetic diversity is an important ongoing task within the breeding community.

Orthopedic issues are among the primary concerns. Hip dysplasia and elbow dysplasia can occur, where the joints do not form correctly and may lead to pain, lameness, and arthritis over time. Ethical breeders test their breeding dogs using official hip and elbow scoring schemes and only breed from animals with satisfactory results. Prospective puppy buyers should always ask to see these scores for both parents and not rely only on verbal reassurance.

Eye health is another area to monitor. Hereditary eye disorders, including cataracts or retinal problems, may occur in some lines. Regular eye examinations by a veterinary ophthalmologist are strongly recommended for breeding dogs. Some clubs and national breed organisations maintain health registers that list tested dogs and their results, which helps breeders make informed choices.

Degenerative myelopathy, a progressive neurological disease that affects the spinal cord, has been found in related breeds like the German Shepherd and is monitored in the Saarloos Wolfdog. There are DNA tests available that identify carriers. Responsible breeding programs use these tests to avoid producing affected puppies while still maintaining as much genetic diversity as possible.

Typical health tests recommended for Saarloos Wolfdogs include:

- Hip dysplasia evaluation  
- Elbow dysplasia evaluation  
- Eye examination by a certified specialist  
- DNA tests for known hereditary conditions where available  

Overall lifespan for the Saarloos Wolfdog often ranges from around 10 to 13 years, with some individuals living longer. As a relatively natural and athletic breed, many remain active well into their senior years if kept at a healthy weight and given appropriate exercise.

Preventive care plays a large role in their wellbeing. A balanced diet, regular veterinary check-ups, and parasite prevention all help protect long-term health. Because the Saarloos Wolfdog can be sensitive and easily stressed, choosing a vet who understands their cautious nature is valuable. Forced handling, noisy waiting rooms, and rushed examinations can increase anxiety, so using calm, low stress techniques is ideal.

Owners should monitor for subtle signs of discomfort, such as reluctance to jump, stiffness after rest, changes in gait, or decreased interest in activities. These may indicate joint issues or other health problems. Regular weight checks are important, since extra kilos place unnecessary strain on the joints and reduce overall quality of life.

Responsible breeding is crucial for this rare breed. Enthusiast breeders often work closely with breed clubs and health committees to plan matings that balance temperament, type, and health. When looking for a puppy, choose breeders who openly discuss health, provide documentation of tests, and explain how they select breeding pairs. This helps support the long term health and sustainability of the Saarloos Wolfdog population.

## History & Origins

The Saarloos Wolfdog was created in the Netherlands in the first half of the twentieth century by Leendert Saarloos, a Dutch dog breeder with a deep fascination for wolves and working dogs. Saarloos believed that modern dogs, particularly German Shepherds, had lost some of the natural, robust qualities he admired. He set out to “reinvigorate” them by carefully introducing wolf blood.

In 1932, he crossed a male German Shepherd Dog, known for its trainability and working ability, with a female European wolf from a zoo. From this foundation, he selected offspring that showed the character and health qualities he wanted, and continued breedings over many generations. His goal was not simply to create a wolf hybrid, but to develop a stable breed that combined the wolf’s natural instincts, strong health, and endurance with the reliability of a domestic dog.

Initially, these dogs were tried as guide dogs for the blind. Their intelligence and stamina were promising, but their cautious, independent nature and natural tendency to avoid busy urban situations made them less suitable for the demanding role of a guide dog. They were also tested for police and military work, but once again their reluctance to confront conflict and their sensitivity to pressure limited their usefulness in those fields.

Over time, it became clear that the Saarloos Wolfdog had a unique character that did not always fit conventional working roles. Instead, they found their place as companions for knowledgeable owners who appreciated a more primitive type of dog. The breed gained official recognition in the Netherlands and was later named after its founder as a tribute to his life’s work.

The Fédération Cynologique Internationale (FCI) recognised the Saarloos Wolfdog as a distinct breed and placed it in Group 1, alongside herding and shepherd dogs, although the Saarloos Wolfdog is not typically used today as a herding dog. In its homeland and several other European countries, breed clubs were established to protect both the physical and mental characteristics of these dogs and to ensure responsible breeding practices.

Modern Saarloos Wolfdogs are still rare outside continental Europe, though interest has slowly grown in other regions. They are mainly kept as companion animals by experienced owners who can meet their special needs. Some are involved in activities such as tracking, search games, or low key outdoor sports that highlight their stamina and keen senses. However, their role remains more that of a natural companion than a specialised working dog.

Throughout their development, breeders and clubs have focused strongly on maintaining the breed’s natural appearance, athletic build, and reserved but nonaggressive temperament. Careful selection and controlled breeding have moved the Saarloos Wolfdog far beyond its early experimental roots into a recognised and distinct breed with a defined standard and a passionate community of enthusiasts.

## Living with the Breed

Sharing your life with a Saarloos Wolfdog is a long term commitment that touches almost every aspect of daily living. This is not a dog that easily adapts to every environment or lifestyle. Before bringing one home, it is important to be honest about your time, space, and experience.

The ideal home for a Saarloos Wolfdog is quiet, stable, and offers plenty of secure outdoor space. A large, well fenced garden is a real advantage. Fencing needs to be sturdy and tall enough to discourage climbing or jumping, and the bottom should be secure so that digging under is difficult. Many Saarloos Wolfdogs are curious explorers, and without proper fencing they may decide to go on adventures on their own.

City life is challenging for this breed. Constant noise, crowds, and busy traffic can be stressful, especially for naturally cautious individuals. A rural or semi rural setting, or at least a very peaceful suburb with access to nature, suits them much better. Daily access to fields, forests, or quiet walking paths allows them to relax and behave more naturally.

Time commitment is another key factor. A Saarloos Wolfdog needs:

- Multiple daily walks, often adding up to several hours of movement and exploration  
- Regular mental stimulation such as scent work, training games, and problem solving toys  
- Patient socialisation, especially during the first two years  

They are not well suited to households where everyone is away for long working days and the dog is left alone for many hours. While they can learn to be alone for moderate periods, they are very attached to their family and may become stressed, vocal, or destructive if consistently left with little company or activity.

Financially, potential owners should be prepared for the normal costs of a large breed dog, including quality food, routine veterinary care, vaccinations, parasite prevention, and insurance where available. Because health testing and responsible breeding are so important for this rare breed, puppies from ethical breeders can be more expensive than some popular breeds. Additionally, you may face extra costs for secure fencing, high quality equipment, and possibly working with a trainer familiar with primitive or wolfdog type breeds.

Useful equipment typically includes:

- A strong, escape proof harness and secure collar  
- A long line for safe exploration in open areas  
- Durable leads and sometimes double leads for added control  
- Sturdy, comfortable bedding in a quiet, private space  
- Enrichment toys such as food puzzles, slow feeders, and scent games  

Crate training can be helpful, but it should be introduced gradually and gently so the dog sees the crate as a safe den rather than a place of punishment. Many Saarloos Wolfdogs appreciate having a quiet corner or room where they can retreat when the household becomes too busy.

Social expectations also matter. Visitors must understand that the dog may not want to be touched or approached immediately. Some Saarloos Wolfdogs will remain aloof with guests for their entire life. This is normal for the breed and should be respected rather than forced. Teaching friends and family to ignore the dog until it chooses to come closer often results in more relaxed interactions.

Living with a Saarloos Wolfdog is not always easy, but it can be deeply fulfilling. You will share your home with a thinking, feeling animal that often responds to the world in a very natural way. If you are patient, respectful, and committed to understanding their unique needs, the Saarloos Wolfdog can become a loyal, observant, and quietly devoted companion who brings a touch of the wild into everyday life.
