Other Names & Breed Recognition

Chien Norvegien De Macareau is the French-language name for the Norwegian Lundehund, translating directly to "Norwegian Puffin Dog." The name reflects the breed's singular historical purpose: hunting Atlantic puffins along the sheer coastal cliffs and rocky islands of northern Norway. In French-speaking contexts, particularly within the Federation Cynologique Internationale's documentation and among francophone breed enthusiasts, this designation has been used to identify the breed alongside its Norwegian name, Norsk Lundehund. The word "macareau" is the French term for puffin (Fratercula arctica), directly paralleling the Norwegian "lunde" in the breed's native name.

The breed carries several additional names across languages and registries. Norwegian Puffin Dog is the most common English-language alternative, providing an immediate description of the breed's original function. Norsk Lundehund is the Norwegian designation used in the breed's country of origin and in the FCI breed standard. Lundehund alone serves as a shortened familiar name used by breed enthusiasts and in casual reference. The name's etymology breaks down clearly: "lunde" from the Norwegian word for puffin and "hund" meaning dog. These naming conventions all point back to the same remarkable animal and its centuries-long association with seabird hunting on the Arctic Norwegian coast.

The Norwegian Lundehund holds the distinction of being the only dog breed developed specifically for puffin hunting, a fact that has shaped every aspect of its anatomy, temperament, and history. This specificity of purpose is reflected across all its names in every language. Unlike many breeds whose names reference geographic origin alone or a general type of work, every name applied to the Lundehund circles back to the puffin. That connection runs so deep that the breed's near-extinction followed directly from the puffin becoming a protected species in the nineteenth century, removing the dog's reason for existence in the eyes of the communities that had maintained it for centuries.

All major kennel organizations recognize the breed under the name Norwegian Lundehund. The American Kennel Club granted full recognition in 2011, placing the breed in the Non-Sporting Group. The United Kennel Club recognized it in 1995 under the Northern Breed Group. The FCI classifies the breed under Group 5, Spitz and Primitive Types, Section 2, Nordic Hunting Dogs, with FCI standard number 265. The Canadian Kennel Club recognizes it within the Non-Sporting Group, and The Kennel Club in the United Kingdom lists it on the Imported Breed Register. Despite this broad recognition, the Lundehund remains critically rare worldwide, with an estimated global population of only around 1,500 to 2,000 dogs, the vast majority living in Norway.

Chien Norvegien De Macareau Organizations & Standards

The Norwegian Lundehund Association of America serves as the AKC parent club for this breed in the United States. The association promotes responsible ownership and breeding, provides health resources specific to the breed's unique gastrointestinal challenges, and connects prospective owners with reputable breeders. Given the breed's extreme rarity, the parent club plays an especially important role in coordinating breeding efforts and maintaining communication between the small community of Lundehund owners and breeders in North America. The club also organizes specialty shows where judges with breed-specific knowledge evaluate dogs against the standard, including the breed's distinctive anatomical features.

In Norway, the Norsk Lundehundklubb (Norwegian Lundehund Club) functions as the primary breed organization and works in close cooperation with the Norsk Kennel Klub. This club has been instrumental in the ongoing outcross project that seeks to address the breed's critically narrow gene pool. The project, approved by the Norwegian Kennel Club, allows carefully planned crosses between the Lundehund and selected related Norwegian breeds, including the Norwegian Buhund, to introduce genetic diversity and improve overall breed health. This outcross program represents one of the most significant conservation breeding initiatives in the purebred dog world and has generated important genetic research data.

The breed standard across registries emphasizes the Lundehund's unique anatomical features as defining characteristics rather than cosmetic preferences. A minimum of six toes on each foot, an elastic neck capable of bending backward to touch the spine, shoulders flexible enough to extend the front legs flat to the side, and ears that can fold closed are all required elements of the standard. These are not optional traits but structural necessities that evolved for the breed's cliff-climbing, cave-navigating work. Judges evaluating the breed are expected to verify these features, and specialty shows often include a Best Feet award recognizing exceptional polydactyl foot structure. The AKC standard notes that these unique characteristics must be present as they define the breed.

The FCI standard, published in its current form in November 2011, closely mirrors the original Norwegian specifications and serves as the reference document for international breed evaluation. It classifies the Lundehund under Group 5, Spitz and Primitive Types, Section 2, Nordic Hunting Dogs, without working trial. The standard describes the breed's utilization as being predestined by its anatomical peculiarities for puffin hunting on steep rocks around fjords and along the shore. This language reflects the understanding that the Lundehund's anatomy is not merely breed type but functional engineering refined over centuries of work in extreme terrain.

Chien Norvegien De Macareau Physical Description

The Norwegian Lundehund is a small, rectangular spitz-type dog that appears unremarkable at first glance but reveals an extraordinary collection of anatomical adaptations upon closer examination. Males stand between 13 and 15 inches at the shoulder, with females slightly smaller at 12 to 14 inches. Weight ranges from 15 to 18 pounds for males and 12 to 15 pounds for females, always in proportion to height. The body is slightly longer than tall, with a length-to-height ratio between 10:9 and 5:4, creating the rectangular outline specified in the breed standard. Males should appear distinctly masculine with slightly more substance, while females present a more refined, feminine outline without sacrificing breed type.

The breed's most immediately striking physical feature is its polydactyl feet. Each foot carries a minimum of six fully formed, jointed, and muscled toes, a trait found in no other standardized dog breed. On the front feet, five toes exhibit three phalangeal joints while one has two. The rear feet carry four toes with three joints and two with two joints, along with elongated rear foot pads. This extra digital equipment provides exceptional grip on wet, uneven rock surfaces and was essential for the dog's ability to climb near-vertical cliff faces while hunting puffins. The toes are not vestigial or cosmetic; they are fully functional and actively used by the dog when navigating terrain.

The Lundehund's flexibility is equally extraordinary and unlike anything found in other domestic dog breeds. The neck possesses an elasticity that allows the head to bend completely backward until it touches the spine, a trait shared only with a few wild canid species such as the New Guinea singing dog and the Australian dingo. This cervical flexibility evolved to allow the dog to turn around inside the narrow tunnels of puffin nesting caves. The shoulder joints permit the front legs to extend laterally at a ninety-degree angle to the body, essentially allowing the dog to splay its forelegs flat to the side like human arms. This shoulder construction produces a distinctive rotary gait that looks unusual but served the critical function of enabling the dog to hug cliff faces during ascent and descent. The ears can fold completely closed, creating a near-tight seal that protected the ear canals from dirt, debris, and the pecking beaks of defensive puffins during cave retrieval work.

The head is wedge-shaped with a moderately wide, slightly rounded skull and prominent brow ridges. The ears are medium-sized, triangular, and carried erect when open. The eyes are slightly oblique and yellowish-brown to brown in color. The double coat consists of a rough, dense outer layer and a soft undercoat, with shorter hair on the head and front of the legs and fuller coverage around the neck and rear thighs. Acceptable coat colors include reddish-brown to fallow with black hair tips and white markings, white with red markings, black, and gray. Mature dogs typically develop more pronounced black tipping in the outer coat than younger animals. The tail is carried in a ring shape or slightly rolled over the topline, though not as tightly curled as in related breeds like the Norwegian Buhund or Norwegian Elkhound.

Affectionate With Family
The Chien Norvegien De Macareau forms strong attachments to its household members and genuinely enjoys being near its people. This breed shows its affection through close physical proximity and animated greetings rather than through overt cuddling, though many individuals do seek lap time on their own terms. The bond between a Lundehund and its family tends to deepen over years, with the dog becoming increasingly attuned to household routines and the emotional states of the people around it.
Good With Young Children
When raised alongside children and properly socialized, the Lundehund can be a patient and engaging companion for younger family members. Its moderate size and generally non-aggressive temperament work in its favor, though its sensitive nature means it may retreat from overly boisterous or unpredictable interactions. Supervision is always appropriate with young children, and kids should be taught to respect the dog's boundaries. The breed's alertness and playful energy can make it a willing participant in gentle games.
Good With Other Dogs
The Lundehund generally coexists well with other dogs, particularly when introduced early and given proper socialization. This breed does not typically exhibit strong same-sex aggression or dominance-driven confrontations, though individual temperaments vary. Its primitive nature means it may communicate differently from more domesticated breeds, using body language and vocalizations that can sometimes be misread by other dogs. Multi-dog households tend to work best when the Lundehund has space to retreat when needed.
Shedding Level
The Lundehund carries a dense double coat that sheds moderately throughout the year, with heavier seasonal blowouts occurring typically twice annually. During these periods, the undercoat releases in substantial quantities and daily brushing becomes necessary to manage loose hair. Outside of shedding season, the coat is relatively self-maintaining and sheds at a manageable rate. Owners should expect to find hair on furniture and clothing but not to the degree seen in heavier-coated spitz breeds.
Coat Grooming Frequency
Outside of seasonal coat blowouts, the Lundehund's grooming needs are modest. A weekly brushing session is typically sufficient to remove loose hair and distribute natural oils through the coat. The breed's rough outer coat has a natural weather-resistant quality that does not require trimming or shaping. Bathing should be infrequent, as the coat's natural oils serve a protective function. Many Lundehunds genuinely enjoy the brushing process, making grooming sessions an opportunity for bonding.
Drooling Level
The Lundehund is an exceptionally clean breed when it comes to drooling. Its spitz-type muzzle structure produces virtually no excess saliva under normal circumstances. Owners will not encounter wet spots on furniture, clothing, or floors from drool. Even during meals or when anticipating treats, the breed maintains a tidy mouth. This low-drool characteristic makes the Lundehund an appealing choice for people who value a clean living environment.
Coat Type
The double coat consists of a harsh, dense outer layer that provides weather protection and a softer undercoat that delivers insulation. The hair is shorter on the head and the front of the legs, with fuller coverage around the neck and along the back of the thighs. The tail carries a dense coat but does not form a flag. This coat evolved to protect the dog during its work on windswept Arctic cliffs and in damp coastal caves, and it continues to serve the breed well in varied climates.
Openness To Strangers
The Lundehund tends toward reserve with unfamiliar people, a trait consistent with its primitive heritage. This caution is not fear-based aggression but rather a thoughtful wariness that reflects the breed's independent character. Given time and the opportunity to observe, most Lundehunds will approach new people on their own terms. Forcing interactions with strangers typically backfires with this breed, as it values the ability to assess situations before engaging. Early socialization helps broaden the dog's comfort zone considerably.
Playfulness Level
Beneath its sometimes reserved exterior, the Lundehund possesses a genuinely playful and mischievous spirit. This breed invents its own games, often involving hiding objects, climbing onto unexpected surfaces, or engaging in spirited chase sequences around the home. Its agility and flexibility lend themselves to acrobatic play that can be genuinely entertaining to watch. The playful streak persists well into adulthood and even into the senior years, making the Lundehund a consistently engaging companion.
Watchdog/Protective Nature
The Lundehund's natural alertness and sensitivity to environmental changes make it an effective watchdog. This breed notices and announces anything out of the ordinary in its territory, from unexpected visitors to unfamiliar sounds. Its bark is sharp and purposeful, serving as a genuine alarm rather than aimless noise. While the breed lacks the physical imposing presence of larger guard dogs, its vigilance and vocal warnings provide meaningful security awareness for its household.
Adaptability Level
The Lundehund can adapt to various living situations, including apartments, provided its exercise and mental stimulation needs are met. However, this breed does not handle abrupt changes in routine, environment, or household composition as easily as some more domesticated breeds. Its primitive nature means it may take longer to settle into a new home or adjust to significant life changes. Consistent routines, patient introduction to new experiences, and a stable home environment bring out the best in this breed's adaptability.
Trainability Level
The Lundehund is intelligent and capable of learning, but its independent and primitive temperament means conventional obedience training can be a slow and sometimes frustrating process. This breed does not share the eager-to-please drive found in herding or sporting breeds, and it will often evaluate whether a given command serves its interests before deciding to comply. Positive reinforcement methods with high-value food rewards yield the best results. Harsh corrections or repetitive drilling will cause the Lundehund to shut down or become avoidant. Patience and creativity in training approaches are essential.

Chien Norvegien De Macareau History & Development

The Norwegian Lundehund is believed to be among the oldest dog breeds in Scandinavia, with written records of dogs used for puffin hunting along the Norwegian coast dating back more than four hundred years. The earliest known written reference appears in 1591, when a regional bailiff visiting the island of Vaeroy noted that the local people used small dogs specially trained to crawl into puffin nesting caves and retrieve the birds alive. Puffin hunting was not a recreational activity for these coastal communities; the birds and their eggs represented a vital protein source in an environment where agriculture was marginal and fishing alone could not sustain the population through long Arctic winters. The dogs were working animals of genuine economic importance.

The breed developed its remarkable anatomical features through centuries of natural and functional selection on the remote Lofoten Islands and other locations along the Norwegian coast above the Arctic Circle. Dogs that could climb vertical rock faces, squeeze into narrow cave passages, turn around in confined spaces, and protect their ears from defensive puffin beaks survived and reproduced. Dogs without these capabilities could not perform the work and were not maintained. This produced an animal uniquely equipped for a single, highly specialized task, with physical traits that have no parallel in any other domestic dog breed. The extra toes, flexible neck, rotary shoulder movement, and closable ears are not genetic accidents but the results of hundreds of years of purposeful use in extreme terrain.

The breed's decline began in the mid-nineteenth century when nets replaced dogs as the primary method of puffin hunting, and a dog tax made maintaining specialized working dogs an economic burden. The puffin's eventual classification as a protected species removed the last practical justification for keeping the breed. By around 1900, the Lundehund survived only in the isolated village of Mostad on the island of Vaeroy in the Lofoten archipelago, where a small working population persisted out of tradition and geographic isolation. The breed was essentially invisible to the wider dog world.

The rescue of the Lundehund from extinction became one of the most dramatic and improbable breed preservation stories in canine history. In the 1930s, Norwegian breeder Eleanor Christie recognized the breed's precarious situation and began obtaining dogs from Mostad. Her efforts were devastated by a distemper epidemic during World War II that swept through Vaeroy and the surrounding islands, reducing the entire world population to just a handful of dogs. A second distemper outbreak in 1963 further decimated the remaining population, leaving roughly five or six closely related dogs from which the entire modern breed descends. Eleanor Christie and fellow enthusiast Christen Lang are credited with painstakingly rebuilding the population from this critically small foundation. The extreme genetic bottleneck resulting from this near-extinction event has profoundly shaped the breed's health profile, particularly its predisposition to gastrointestinal disease, and has motivated the Norwegian Kennel Club's ongoing outcross program to introduce fresh genetic material from related Nordic breeds.

Chien Norvegien De Macareau Temperament & Personality

The Lundehund's temperament reflects its heritage as a primitive, independently operating working dog. Unlike breeds developed for close handler partnership such as retrievers or herding dogs, the Lundehund was expected to work autonomously in puffin caves, making its own decisions about how to navigate tight spaces, locate birds, and extract them. This history produced a dog that thinks for itself, evaluates situations before acting, and does not automatically defer to human direction. Owners accustomed to breeds that live to please will need to adjust their expectations. The Lundehund respects partnership but does not offer blind obedience, and this independence is a feature of the breed rather than a flaw to be trained away.

Within its household, the Lundehund is genuinely affectionate and forms deep bonds with family members. It tends to be most closely attached to one or two primary people while remaining friendly with the broader household. The breed shows its affection through physical proximity, animated greetings, and a willingness to participate in family activities rather than through constant physical contact. Many Lundehunds have a playful, almost clownish side that emerges once they are comfortable in their environment, inventing games, performing acrobatic maneuvers that showcase their extraordinary flexibility, and generally keeping their families entertained with their antics.

With strangers, the Lundehund is characteristically reserved. This wariness is not aggression; it is a watchful caution rooted in the breed's primitive nature. The dog will typically observe unfamiliar people from a distance before deciding whether to approach, and forcing introductions tends to increase rather than decrease its suspicion. Given the opportunity to assess newcomers at its own pace, most Lundehunds will eventually warm up, though they rarely become effusively friendly with people outside their immediate circle. This reserved quality, combined with the breed's alert and vocal nature, makes the Lundehund an effective watchdog that takes notice of anything unusual in its environment.

The breed carries a moderate to strong prey drive consistent with its hunting heritage. While the Lundehund was bred to retrieve birds rather than kill them, its instinct to pursue small, fast-moving animals remains active. This means outdoor activities in unfenced areas require caution, and the breed cannot be reliably trusted off-leash in environments where wildlife or small animals are present. Socialization with cats and other household pets from an early age can produce harmonious coexistence, but the prey drive should be respected and managed rather than assumed to disappear. The Lundehund's alertness, curiosity, and desire to investigate its surroundings are defining personality traits that enrich life with the breed but also demand thoughtful management.

Chien Norvegien De Macareau Family Life & Living Requirements

The Lundehund can adapt to various living situations, including apartments, provided its physical and mental needs are met consistently. Its small size works in its favor for urban living, and the breed is not inherently destructive or excessively noisy when properly exercised. However, prospective owners should understand that this is a primitive breed with different household integration needs than more domesticated companion breeds. The Lundehund may take longer to settle into a new home, may be initially wary of household appliances and unfamiliar stimuli, and may require patient acclimation to urban sounds and environments. Once settled, however, the breed tends to become a comfortable and entertaining household companion.

Secure fencing is a non-negotiable requirement for any Lundehund household with outdoor space. The breed's extraordinary physical flexibility means it can squeeze through gaps, climb obstacles, and navigate escape routes that would stop other small dogs. Standard fencing that contains most breeds may not be sufficient. Owners need to inspect their fencing for gaps, check that the dog cannot climb over or dig under barriers, and supervise outdoor time, particularly during the initial period in a new home. The Lundehund's curiosity and independent nature mean it will test boundaries, and its physical capabilities mean it can exploit weaknesses that other breeds would never discover.

Housetraining the Lundehund requires patience and consistency. The breed is not among the easiest to housetrain, and many owners report that establishing reliable indoor cleanliness takes longer than with more domesticated breeds. Crate training typically proves effective, as the Lundehund's cave-dwelling heritage means it generally takes well to a den-like space. Consistency in schedule, positive reinforcement for appropriate elimination, and management of the environment to prevent mistakes are the keys to success. Accidents should be expected during the training period without frustration, as the breed responds poorly to correction-based housetraining methods.

Families with children will find that the well-socialized Lundehund can be a good companion, provided children understand how to interact respectfully with a sensitive, independent dog. The breed does not typically tolerate rough handling, ear pulling, or sudden grabs, and it will usually choose to retreat rather than snap when overwhelmed. Teaching children to let the dog approach on its own terms, to avoid disrupting it while eating or sleeping, and to participate in calm, structured play produces the best outcomes. The Lundehund's playful energy and moderate size make it a viable playmate for older children who have learned appropriate dog-handling skills.

Chien Norvegien De Macareau Training & Exercise Needs

Training the Lundehund demands a fundamentally different approach than what works with eager-to-please breeds. Conventional obedience methods built around repetition and compliance tend to fail with this breed, not because the dog lacks intelligence but because it evaluates the value proposition of every command. The Lundehund learns quickly when motivated but reserves judgment about whether any particular instruction merits consistent compliance. High-value food rewards are typically the most effective motivator, as the breed is generally food-oriented. Training sessions should be kept short, varied, and positive, ending before the dog loses interest. The moment a Lundehund checks out mentally, continued training becomes counterproductive.

Socialization during the critical developmental period is especially important for this naturally reserved breed. Exposure to a wide variety of people, environments, sounds, surfaces, and other animals during puppyhood helps establish a broader comfort zone that will benefit the dog throughout its life. The Lundehund's primitive temperament means it is more likely than many breeds to develop neophobia, a persistent fear of novel stimuli, if early socialization is insufficient. Puppy classes, controlled exposure to urban environments, and positive experiences with diverse groups of people should be prioritized during the first four to sixteen weeks and continued regularly thereafter.

Exercise needs are moderate to high, reflecting the breed's athletic heritage and active mind. Daily walks of thirty to sixty minutes, supplemented with opportunities for free play in secure areas, generally satisfy the breed's physical requirements. The Lundehund's agility and climbing ability mean it excels at activities that challenge its body in varied ways, such as hiking over uneven terrain, exploring rocky areas, and navigating natural obstacles. Flat, repetitive exercise like treadmill walking fails to engage the breed's need for environmental stimulation. Mental enrichment through puzzle feeders, scent work, and novel exploration opportunities is equally important and can help compensate on days when outdoor exercise is limited.

The breed can participate in various organized dog sports, though its independent nature means competitive obedience and precision-based activities may produce mixed results. Agility appeals to the Lundehund's physical talents but requires a patient approach to training the necessary compliance elements. Barn hunt and nose work align naturally with the breed's instincts and often produce enthusiastic participation. Rally obedience offers a more relaxed framework than traditional obedience and can be a good fit. The key across all training and exercise activities is to work with the Lundehund's nature rather than against it, building a cooperative relationship based on mutual respect rather than demanding subordination.

Chien Norvegien De Macareau Health Concerns

The health profile of the Norwegian Lundehund is dominated by the gastrointestinal complex known as Lundehund syndrome, a constellation of related digestive disorders that affects the breed at rates far exceeding any other dog breed. This syndrome encompasses intestinal lymphangiectasia, protein-losing enteropathy, inflammatory bowel disease, and chronic atrophic gastritis. Estimates suggest that a significant majority of Lundehunds will develop some degree of intestinal disease during their lifetime, though severity varies enormously from subclinical cases with no visible symptoms to severe, life-threatening episodes requiring intensive veterinary intervention. The condition results from the breed's extreme genetic bottleneck, with the entire modern population descending from approximately five or six closely related dogs that survived the population collapse of the 1960s.

Lundehund syndrome manifests through chronic or intermittent diarrhea, vomiting, weight loss, poor coat condition, lethargy, and in severe cases, edema and ascites from protein loss. The most insidious aspect of the condition is its ability to remain subclinical for years before presenting suddenly with severe symptoms. A Lundehund can appear perfectly healthy while its serum albumin levels gradually decline, with the first visible signs appearing only when the disease has progressed significantly. This makes regular veterinary monitoring with blood work including serum albumin measurements essential for all Lundehunds, regardless of apparent health status. A mutation in the LEPREL1 gene has been identified as a contributing factor, and genetic testing through services like Embark is available to identify affected and carrier dogs.

There is currently no cure for Lundehund syndrome, but the condition can be managed in many dogs through careful dietary and medical intervention. A low-fat, high-protein diet with easily digestible ingredients has shown positive effects on gastrointestinal health in affected dogs. Avoiding sudden food changes is critically important, as dietary disruptions can trigger acute episodes. Some dogs require ongoing medical management including corticosteroids, antibiotics for secondary small intestinal bacterial overgrowth, and nutritional supplementation. The prognosis varies widely depending on the severity and the dog's individual response to management protocols. Many dogs with well-managed Lundehund syndrome live relatively normal, comfortable lives, while others experience repeated acute episodes that significantly impact quality of life.

Beyond Lundehund syndrome, the breed may be affected by patellar luxation, follicular dysplasia, and eye conditions. Patellar luxation occurs at moderate frequency and ranges from mild intermittent slipping to persistent displacement requiring surgical correction. Follicular dysplasia affects coat quality and can produce patchy hair loss. These conditions, while worth monitoring, are secondary concerns relative to the gastrointestinal issues that define the breed's health landscape. The Norwegian Kennel Club's outcross program, which introduces genetic material from related breeds like the Norwegian Buhund through carefully planned crosses, represents the most significant long-term effort to address the Lundehund's health challenges by widening the breed's dangerously narrow gene pool.

Common Health Issues

  • Lundehund syndrome (intestinal lymphangiectasia / protein-losing enteropathy) - A breed-defining gastrointestinal disorder encompassing intestinal lymphangiectasia, protein-losing enteropathy, and inflammatory bowel disease. A significant majority of Lundehunds will develop some degree of intestinal disease during their lifetime, ranging from subclinical to severe and life-threatening. The condition results in chronic diarrhea, vomiting, weight loss, edema, and ascites due to the inability to properly absorb nutrients and protein from food. A mutation in the LEPREL1 gene has been identified as a contributing factor, and genetic testing is available.
  • Chronic atrophic gastritis - Frequently occurs alongside Lundehund syndrome and involves progressive thinning and inflammation of the stomach lining, leading to reduced digestive capacity and nutrient absorption. Dogs with this condition may show intermittent vomiting, appetite changes, and gradual weight loss that can be difficult to distinguish from other gastrointestinal issues without endoscopic evaluation.
  • Gastric carcinoma - Lundehunds with chronic atrophic gastritis face an elevated risk of developing gastric neoplasms, including carcinoma. The progression from chronic gastritis to neoplasia can occur over years, making regular veterinary monitoring of gastrointestinal health essential for early detection. This risk is directly linked to the breed's predisposition to chronic stomach inflammation.
  • Small intestinal bacterial overgrowth (SIBO) - An overpopulation of bacteria in the small intestine that disrupts normal digestion and nutrient absorption, frequently occurring as a component of or alongside Lundehund syndrome. Symptoms include chronic diarrhea, flatulence, and poor coat condition. Management typically involves dietary modification and intermittent antibiotic therapy under veterinary supervision.
  • Patellar luxation - Displacement of the kneecap from its normal groove, ranging from occasional intermittent slipping to persistent dislocation causing lameness. The condition occurs at moderate frequency in the breed and can be evaluated through veterinary orthopedic examination. Severe cases may require surgical correction to restore normal joint function.
  • Follicular dysplasia - An inherited coat disorder affecting the normal growth cycle of hair follicles, resulting in patchy hair loss, poor coat quality, and sometimes secondary skin infections. The condition is not life-threatening but requires veterinary dermatological management and may affect the dog's appearance throughout its life.

Preventive Care & Health Monitoring

  • LEPREL1 genetic test for Lundehund syndrome - Request documentation from the breeder showing the genetic status of both parents for the LEPREL1 mutation associated with intestinal lymphangiectasia. While the condition affects the breed at high rates regardless of genetic status, knowing carrier status helps breeders make informed decisions and prepares owners for proactive management.
  • Regular serum albumin and total protein monitoring - Routine blood work measuring serum albumin levels should be performed at least twice yearly, even in asymptomatic dogs, because Lundehund syndrome can be subclinical for years before suddenly presenting with severe symptoms. Early detection of declining protein levels allows dietary and medical intervention before clinical signs become severe.
  • Low-fat, high-protein dietary management - A diet low in fat and higher in easily digestible protein has demonstrated significant positive effects on gastrointestinal health in this breed. Avoid abrupt food changes, which can trigger acute episodes of intestinal distress. Work with a veterinarian experienced in Lundehund gastrointestinal disease to establish an appropriate feeding protocol.
  • Patellar luxation evaluation - Veterinary orthopedic examination of the kneecaps should be performed to identify any degree of luxation. Early detection allows for appropriate exercise modification and monitoring to prevent progression.
  • Regular paw and extra toe maintenance - The breed's polydactyl feet require regular attention to ensure all six toes on each foot are trimmed properly, as the extra toes may not wear down naturally through normal activity. Interdigital areas should be kept clean and dry to prevent infections, particularly in wet or muddy conditions.
  • Connect with breed club veterinary resources - The Norwegian Lundehund Association of America and international Lundehund breed clubs maintain lists of veterinarians experienced with Lundehund syndrome and breed-specific health management. Given the breed's rarity and unique health profile, establishing a relationship with a veterinarian familiar with the breed's specific needs is strongly recommended.

Chien Norvegien De Macareau Grooming & Maintenance

The Lundehund's grooming requirements are modest compared to many breeds, reflecting its heritage as a working dog in harsh conditions where elaborate coat maintenance was neither practical nor desirable. The double coat consists of a rough, dense outer layer and a soft undercoat that together provide natural weather resistance. This coat is presented naturally with no trimming, clipping, or shaping required by the breed standard. The natural coat texture repels dirt effectively, and dried mud typically brushes out easily once dry. Bathing should be infrequent, limited to occasions when the dog is genuinely dirty or has encountered something odorous, as frequent bathing strips the coat of its natural protective oils.

Weekly brushing is sufficient during most of the year to remove loose hair, distribute natural oils, and maintain coat health. A slicker brush and an undercoat rake are the primary tools needed. During seasonal coat blowouts, which typically occur twice yearly, the undercoat sheds in substantial quantities and daily brushing becomes necessary to manage the volume of loose hair. The shedding during these periods can be impressive for a small dog, and owners should be prepared for several weeks of elevated hair loss. Regular brushing during the blowout significantly reduces the amount of hair deposited on furniture, clothing, and household surfaces. Many Lundehunds enjoy the grooming process and will lean into the brush, making these sessions a positive bonding experience.

Paw care requires special attention in this breed due to the extra toes. All six toes on each foot need regular nail trimming, as some of the additional digits may not contact the ground during normal movement and therefore do not wear down naturally. Allowing the nails on these extra toes to grow unchecked can lead to curling, snagging, and potential injury. The interdigital spaces between the toes should be checked regularly for debris, moisture buildup, and signs of irritation or infection, particularly after walks in wet or muddy conditions. Owners should establish a paw-handling routine from puppyhood so the dog is comfortable having all its toes examined and trimmed.

Dental care follows the standard recommendations for all small breeds, with regular tooth brushing being the most effective method of preventing periodontal disease. Ear care is straightforward despite the breed's unusual ear anatomy; the ears should be checked weekly for signs of redness, discharge, or odor. The Lundehund's ability to fold its ears closed is a protective mechanism that actually reduces the risk of debris entering the ear canal compared to permanently erect-eared breeds. Overall, the Lundehund is a low-maintenance breed from a grooming perspective, with the primary ongoing investment being the management of its gastrointestinal health rather than its exterior appearance.
