Other Names

The Kochi-ken is also known by several regional and historical names. In its native Japan, it may be referred to as the Kochi Prefecture Dog or simply as a regional variant of the ancient Japanese hunting breeds. Some enthusiasts and breeders may use terms like Japanese Mountain Dog or Kochi Hunting Dog when describing this breed's original function. The name "ken" translates to "dog" in Japanese, making Kochi-ken literally mean "Kochi dog," referencing the Kochi Prefecture where this breed has deep historical roots. Occasionally, you might encounter references to this breed in historical texts as part of the broader classification of Japanese native breeds or indigenous hunting dogs of Shikoku Island. These various names reflect both the geographical origins and the traditional roles these dogs have played in Japanese mountain communities for centuries.

Kochi-ken Description

The Kochi-ken represents one of Japan's most treasured primitive breeds, embodying centuries of careful breeding and natural selection in the mountainous regions of Kochi Prefecture. This medium-sized spitz-type dog displays a remarkable combination of athletic prowess, unwavering loyalty, and an independent spirit that has made them exceptional hunting companions and devoted family guardians. Their physical appearance immediately suggests their working heritage, with a well-balanced, muscular frame that speaks to their agility and endurance in challenging terrain.

Standing proudly with their characteristic curled tail carried over their back and pointed, erect ears that miss nothing in their environment, the Kochi-ken presents an alert and dignified bearing that commands respect. Their double coat provides excellent protection against harsh weather conditions, consisting of a dense, soft undercoat beneath a straight, coarse outer coat that naturally repels water and debris. The coat typically appears in striking color combinations including red, black and tan, or brindle patterns, with each individual dog displaying subtle variations that make them uniquely beautiful.

What truly sets the Kochi-ken apart is their extraordinary intelligence and problem-solving ability. These dogs were bred to work independently in the mountains, making split-second decisions while tracking wild boar and other game through difficult terrain. This independent thinking, while making them capable and reliable working dogs, also means they require owners who understand and respect their need for mental stimulation and purposeful activity. They are not content to be mere lapdogs but thrive when given tasks that challenge their considerable intellect.

The breed's temperament reflects their heritage as both hunting dogs and family companions. They form incredibly strong bonds with their human families, often choosing one person as their primary focus while maintaining affectionate relationships with other family members. Their loyalty is legendary, and they will defend their home and family with courage and determination. However, this protective instinct comes with the need for proper socialization from an early age to ensure they develop appropriate responses to new people and situations.

In terms of physical capabilities, the Kochi-ken possesses remarkable stamina and agility. Their compact, well-muscled body allows them to navigate rocky terrain, dense forests, and steep mountainsides with ease. Their gait is smooth and efficient, designed for covering long distances without tiring quickly. The breed's natural hunting instincts remain strong, and they may display behaviors such as stalking, pointing, and tracking even in domestic settings, making them excellent candidates for various dog sports and activities that tap into these natural abilities.

The Kochi-ken's facial expression is particularly striking, with dark, intelligent eyes that seem to assess and understand everything around them. Their wedge-shaped head and well-proportioned features give them a noble appearance that reflects their dignified nature. When alert, their ears stand perfectly erect, and their intense gaze suggests a dog that is always ready for action or adventure.

Training a Kochi-ken requires patience, consistency, and understanding of their independent nature. They are highly intelligent and capable of learning complex commands and tasks, but they may question the necessity of repetitive exercises or commands that seem pointless to them. Positive reinforcement methods work best, as these dogs respond well to praise and rewards while maintaining their dignity and self-respect. Harsh training methods are counterproductive and can damage the trust that is essential to a successful relationship with this breed.

The social nature of the Kochi-ken is complex and fascinating. While they are devoted to their families, they can be reserved with strangers, taking time to assess new people before deciding whether to accept them. This cautious approach to strangers is not fearfulness but rather a careful evaluation process that served them well in their working roles. Once they accept someone, however, that person becomes part of their trusted circle and will be greeted with warmth and affection.

Other Organizations

The Japan Kennel Club (JKC) recognizes the Kochi-ken as part of their native breed preservation program, maintaining detailed standards that emphasize the breed's hunting capabilities and regional characteristics. The standard focuses on maintaining the breed's original type, working ability, and temperament. Regional kennel clubs in Japan work closely with the JKC to preserve bloodlines and ensure breeding practices maintain the breed's distinctive characteristics. Some international rare breed organizations and specialty clubs have developed their own standards based on the JKC guidelines, adapting them for their specific regions while maintaining the essential breed type and characteristics.

Kochi-ken History

The history of the Kochi-ken is deeply intertwined with the rugged landscape and hunting traditions of Japan's Kochi Prefecture, located on the southern coast of Shikoku Island. Archaeological evidence suggests that spitz-type dogs similar to the modern Kochi-ken have inhabited this region for over a thousand years, arriving with early human settlers who needed reliable hunting companions to navigate the challenging mountain terrain and dense forests that characterize much of Shikoku.

During the Kamakura period (1185-1333), written records begin to appear describing dogs used by local hunters for tracking wild boar in the mountains surrounding what is now Kochi City. These early accounts describe dogs with remarkable courage and tenacity, capable of working independently for hours while pursuing dangerous game through terrain that would challenge even the most experienced human hunters. The isolation of many mountain communities during this period led to the development of distinct local lines, as different villages bred their dogs for specific hunting conditions and prey types common to their particular regions.

The Edo period (1603-1868) marked a significant phase in the breed's development, as Japan's policy of isolation meant that foreign dog breeds had minimal influence on the native populations. During this time, the Kochi-ken became highly specialized for hunting the formidable Ryukyu wild boar, a species known for its aggressive nature and exceptional intelligence. Hunters required dogs that could not only track and bay these dangerous animals but also demonstrate the courage to hold them at bay until the hunter could arrive. This selective pressure resulted in dogs with exceptional bravery, strong protective instincts, and the intelligence to make split-second decisions in life-threatening situations.

The Meiji Restoration of 1868 brought significant changes to Japanese society, including new attitudes toward dog breeding and the introduction of Western hunting practices. However, the remote mountain regions of Kochi Prefecture remained largely unchanged, and local hunters continued to rely on their traditional hunting dogs. In fact, the opening of Japan to international trade increased demand for wild boar meat and hides, leading to an intensification of hunting activities and a greater appreciation for the skills of the local hunting dogs.

The early 20th century presented new challenges for the Kochi-ken population. Rapid modernization, urbanization, and changing lifestyle patterns meant that fewer people engaged in traditional hunting practices. Additionally, the introduction of foreign dog breeds and the crossbreeding that sometimes resulted threatened the purity of the native lines. Recognizing this threat, dedicated breeders and hunters in the Kochi region began making conscious efforts to preserve the pure bloodlines of their traditional hunting dogs.

World War II had a devastating impact on many Japanese dog breeds, and the Kochi-ken was no exception. Food shortages, the requisitioning of dogs for military purposes, and the general disruption of normal life meant that many breeding programs were abandoned or interrupted. Some of the most carefully maintained bloodlines were lost during this period, as families struggled to feed themselves, let alone maintain breeding dogs. The immediate post-war period saw a continued decline in numbers as Japan focused on rebuilding its cities and economy.

The 1950s and 1960s marked the beginning of serious conservation efforts for the Kochi-ken. Japanese cynologists and breed enthusiasts, recognizing the cultural and genetic value of their native breeds, began systematic efforts to locate, document, and preserve the remaining pure specimens. These efforts were complicated by the fact that many dogs had been crossbred during the difficult war years, making it challenging to identify truly pure examples of the breed. Dedicated researchers traveled throughout the mountain regions of Kochi Prefecture, interviewing elderly hunters and examining their dogs to identify animals that still carried the traditional characteristics and bloodlines.

During the 1970s, the Japan Kennel Club took an active role in preserving the Kochi-ken, establishing breeding standards and registration systems to maintain accurate records of bloodlines and breeding activities. This period saw the establishment of several important kennels dedicated to preserving the breed, with breeders working closely with hunters who still used these dogs in their traditional roles. The emphasis during this period was on maintaining working ability alongside correct physical type, ensuring that the breed retained its essential characteristics and capabilities.

The 1980s and 1990s brought increased international interest in Japanese native breeds, and the Kochi-ken began to attract attention from dog enthusiasts outside Japan. However, this international interest was balanced with a commitment to maintaining the breed's essential characteristics and ensuring that increased demand did not lead to irresponsible breeding practices. Japanese breed organizations worked carefully to establish export protocols that would maintain breed quality while allowing for the establishment of breeding programs in other countries.

In recent decades, the Kochi-ken has faced new challenges related to changing lifestyles in Japan. As hunting has become less common and urban living has increased, fewer people have the lifestyle necessary to properly maintain these active, intelligent dogs. However, the breed has found new roles in dog sports, search and rescue work, and as companions for active families who appreciate their intelligence and loyalty. Modern breed preservation efforts focus on maintaining genetic diversity while ensuring that the essential working characteristics and temperament that define the breed are not lost.

Today, the Kochi-ken remains a relatively rare breed, even within Japan. Conservation efforts continue under the guidance of the Japan Kennel Club and various regional breed clubs, with careful attention paid to maintaining genetic health and the breed's distinctive characteristics. While the breed faces the ongoing challenge of limited genetic diversity common to many rare breeds, dedicated breeders and enthusiasts continue to work toward ensuring that future generations will be able to experience the remarkable intelligence, loyalty, and working ability that have defined the Kochi-ken for centuries.

Kochi-ken Function

The primary function of the Kochi-ken throughout its history has been as a hunting dog specifically developed for tracking and holding wild boar in the mountainous terrain of Kochi Prefecture. This specialized role required dogs with exceptional physical capabilities, unwavering courage, and the intelligence to work independently in challenging and dangerous situations. Unlike pack hunting dogs that work in large groups, the Kochi-ken was typically worked alone or in pairs, requiring each dog to possess complete self-reliance and excellent judgment.

In their traditional hunting role, Kochi-ken demonstrated remarkable tracking abilities, using their keen scent and hearing to locate wild boar that had taken refuge in dense undergrowth or rocky crevices. Their compact, muscular build allowed them to navigate through thick vegetation and over rough terrain that would stop larger dogs, while their agility enabled them to dodge the quick, aggressive charges of cornered boar. The breed's distinctive bark served as a communication tool, alerting hunters to the location of game while also serving to keep the boar focused on the dog rather than escaping.

Beyond their hunting prowess, Kochi-ken served important guardian functions in their mountain communities. Their natural territorial instincts and protective nature made them excellent watchdogs for isolated farms and villages, where they would alert residents to the approach of both human intruders and dangerous wildlife. Their ability to distinguish between normal forest sounds and genuine threats made them invaluable in areas where wild animals posed ongoing risks to livestock and property.

The breed's intelligence and trainability also made them useful for other working roles within their communities. Some were trained to help with livestock management, using their natural herding instincts to move cattle and other animals in the mountainous grazing areas. Their sure footing and endurance made them excellent companions for shepherds and farmers who needed to traverse difficult terrain regularly. Additionally, their loyalty and protective nature made them trusted companions for travelers navigating the mountain paths that connected remote communities.

In modern times, the Kochi-ken's function has evolved to meet contemporary needs while maintaining its essential working characteristics. Many of these dogs now excel in various dog sports and competitions that tap into their natural abilities. Tracking competitions allow them to use their exceptional scenting skills, while agility trials challenge their physical capabilities and quick thinking. Some Kochi-ken have found success in search and rescue work, where their independent thinking, endurance, and determination prove invaluable in locating missing persons in challenging terrain.

The breed's natural protective instincts continue to make them effective guard dogs for homes and properties, particularly in rural or semi-rural settings where their territorial nature and alertness are most appreciated. Their tendency to form strong bonds with their families makes them excellent personal protection dogs, as they will defend their loved ones with courage and determination while remaining manageable and responsive to their owner's commands.

As companion animals, Kochi-ken serve the important function of providing devoted, intelligent partnerships for active individuals and families. Their need for mental and physical stimulation makes them ideal companions for hikers, runners, and outdoor enthusiasts who can provide the exercise and adventure these dogs crave. Their loyalty and affectionate nature with family members, combined with their natural caution around strangers, makes them excellent family protectors who can differentiate between normal social interactions and genuine threats.

The breed's intelligence and problem-solving abilities have also made them suitable for therapy work in some contexts, particularly with individuals who appreciate their calm, dignified demeanor and intuitive understanding of human emotions. Their ability to remain calm under pressure and their natural empathy make them effective in providing emotional support, though their independent nature means they work best with handlers who understand and respect their need for autonomy.

In agricultural settings, some Kochi-ken continue to serve traditional functions related to wildlife management and property protection. Their natural ability to deter wild animals from crops and livestock areas makes them valuable assets for farmers dealing with ongoing wildlife pressures. Their efficiency in this role stems from their ability to patrol large areas independently and their effectiveness in using non-lethal deterrent methods to manage wildlife conflicts.

Looking toward the future, the Kochi-ken's versatile abilities and strong work ethic suggest continued relevance in various functional roles. As interest in outdoor recreation and adventure sports continues to grow, these dogs may find new opportunities as adventure companions and sporting partners. Their natural abilities and trainability also make them candidates for specialized working roles that may emerge as society's needs evolve, always building upon the foundation of intelligence, loyalty, and independence that has defined the breed for centuries.

Kochi-ken Behavior

The behavioral characteristics of the Kochi-ken reflect centuries of selective breeding for independent hunting work in challenging mountain environments. These dogs exhibit a complex behavioral profile that combines fierce loyalty to their families with a strong independent streak that can sometimes challenge inexperienced dog owners. Understanding and working with these natural behavioral tendencies is essential for anyone considering sharing their life with a Kochi-ken.

One of the most prominent behavioral characteristics of the Kochi-ken is their extraordinary loyalty and devotion to their human family. This loyalty often manifests as a preference for one primary person, though they maintain affectionate relationships with other family members. They have an almost intuitive ability to read their owner's moods and emotions, often responding to subtle changes in body language or tone of voice before their human is even fully aware of their own emotional state. This sensitivity makes them remarkably attuned companions but also means they can be affected by household stress or conflict.

The breed's independence is both one of their greatest strengths and one of their most challenging characteristics for modern pet owners. Bred to make life-or-death decisions while hunting alone in the mountains, Kochi-ken naturally question commands that don't make sense to them and may choose alternative solutions to problems. This independent thinking should not be mistaken for stubbornness or disobedience; rather, it represents intelligent problem-solving that served them well in their working roles. Successful training requires owners to present tasks in ways that engage the dog's intelligence and show clear purpose.

Territorially, Kochi-ken display strong protective instincts that extend to both their physical territory and their human family. They are naturally suspicious of strangers and will carefully evaluate new people before deciding whether to accept them. This cautious approach to strangers is not fearfulness but rather a careful assessment process that helped their ancestors distinguish between friendly travelers and potential threats. Once they accept someone into their circle of trust, however, that person will be greeted warmly and defended if necessary.

The breed's hunting heritage manifests in several distinctive behavioral patterns that owners should understand and manage appropriately. They possess a strong prey drive that may cause them to chase small animals, and their tracking instincts mean they can become intensely focused on interesting scents, sometimes to the exclusion of everything else around them. This behavior is not defiance but rather the expression of deep-seated instincts that have been honed over centuries. Providing appropriate outlets for these hunting behaviors through activities like tracking games or scent work can help satisfy these natural urges.

Socially, Kochi-ken tend to be somewhat reserved and dignified in their interactions with both humans and other dogs. They rarely display the exuberant, outgoing personality typical of some breeds, preferring instead to observe and assess situations before committing to interaction. With proper socialization from an early age, they can be quite social, but they will always maintain a certain dignity and selectiveness in their relationships. They tend to form deeper, more meaningful bonds rather than superficial friendships with many individuals.

The breed's communication style is sophisticated and varied, involving not just vocalizations but also body language and behavioral cues. They are generally not excessive barkers, reserving their voice for genuinely important communications such as alerting to potential threats or expressing strong emotions. Their bark tends to be deep and authoritative, reflecting their serious nature and their role as guardians. They also communicate through subtle changes in posture, ear position, and facial expressions that attentive owners learn to interpret over time.

Intellectually, Kochi-ken demonstrate remarkable problem-solving abilities and memory. They can learn complex routines and remember them for years, often anticipating their owner's needs based on subtle environmental cues. Their intelligence manifests not just in their ability to learn commands but in their capacity to understand context and make appropriate decisions in novel situations. This intelligence requires mental stimulation to prevent boredom, which can lead to destructive behaviors or depression.

The breed's energy patterns reflect their working heritage, with periods of intense activity followed by deep rest. They are capable of incredible bursts of energy and focus when engaged in activities that interest them, but they also appreciate quiet time for reflection and observation. This pattern makes them well-suited to active owners who can provide exciting adventures followed by peaceful home time, but poorly suited to owners who expect constant, moderate activity levels.

Emotionally, Kochi-ken are remarkably stable and resilient, but they form deep emotional bonds that make them sensitive to changes in their family structure or living situation. They handle physical challenges and discomfort with stoic courage, but emotional stress or the loss of a beloved family member can affect them deeply. They require patient, understanding handling during difficult transitions and may need extra time and support to adjust to major changes in their lives.

The breed's natural behaviors also include a strong denning instinct, leading them to seek out secure, comfortable spaces where they can retreat when they need rest or want to observe their surroundings safely. They often choose elevated positions that allow them to survey their territory, reflecting their heritage as mountain dogs who needed to watch for both prey and predators. Providing appropriate spaces that satisfy this need for security and observation helps them feel comfortable and confident in their home environment.

Kochi-ken Family Dynamics

The integration of a Kochi-ken into family life creates a unique dynamic that reflects the breed's distinctive personality traits and historical background. These dogs form incredibly strong bonds with their human families, but the nature of these relationships is influenced by their independent heritage and their natural tendency to form hierarchical social structures. Understanding these dynamics is crucial for families considering adding a Kochi-ken to their household.

Within the family structure, Kochi-ken typically establish a primary bond with one family member while maintaining affectionate but secondary relationships with others. This bonding pattern often develops naturally based on who spends the most time with the dog, provides training and care, or simply has a personality that resonates with the dog's temperament. The chosen person becomes the dog's primary focus and the individual they look to for guidance and leadership in uncertain situations. This special relationship should be respected and nurtured, as it forms the foundation for successful training and behavior management.

The breed's relationship with children requires careful consideration and proper management. While Kochi-ken can be wonderful with children when properly socialized and trained, their independent nature and protective instincts mean they are better suited to families with older children who understand how to interact respectfully with dogs. Young children's unpredictable movements and loud vocalizations can sometimes trigger the dog's protective instincts inappropriately, and their independent nature means they may not tolerate rough handling or disrespectful treatment that other breeds might accept.

When properly introduced and socialized, Kochi-ken often become devoted protectors of family children, understanding intuitively when supervision and protection are needed. They may position themselves between children and strangers, or alert parents to situations they perceive as potentially dangerous. However, this protective instinct requires careful management to ensure the dog doesn't become overly restrictive of children's normal social interactions or activities. Early socialization with children of various ages and consistent training are essential for developing appropriate responses.

The breed's interaction with elderly family members often highlights their gentler, more intuitive side. Many Kochi-ken seem to understand when family members are fragile or vulnerable and will adjust their behavior accordingly, becoming gentler and more careful in their movements and interactions. Their natural alertness and protective instincts can make them excellent companions for elderly family members, providing both security and companionship while respecting the person's need for independence.

In multi-pet households, Kochi-ken dynamics depend heavily on early socialization and the individual dog's personality. Their hunting heritage means they may have strong prey drives toward smaller animals, making careful introduction and supervision essential when cats, rabbits, or other small pets are present. With other dogs, they tend to be somewhat selective in their friendships, preferring to establish clear social hierarchies rather than engaging in rough, egalitarian play. They often do best with dogs that respect their need for personal space and don't challenge their authority.

The breed's territorial nature extends to their concept of family space, and they often develop complex understanding of household routines and territories. They may designate certain areas of the home as their responsibility to guard, while allowing family members free access to other areas. This territorial awareness can be beneficial for home security but requires management to ensure the dog doesn't become overly restrictive of normal household activities or visitor access.

Family routines and schedules often become deeply important to Kochi-ken, who thrive on predictability and structure. They quickly learn family patterns and may become anxious or unsettled when routines are disrupted without explanation. Involving them in family activities and maintaining consistent schedules helps them feel secure and reduces stress-related behaviors. They often anticipate family needs and activities, positioning themselves to be helpful or simply to observe important family interactions.

The breed's communication within the family context is sophisticated and multifaceted. They develop different interaction styles with different family members, adjusting their approach based on each person's personality and role within the family. With their primary person, they may be more physically affectionate and responsive to subtle cues, while with other family members they may be more formal but still clearly devoted. Understanding and respecting these different relationship styles helps maintain harmony within the family structure.

Training and behavior management within the family requires a coordinated approach where all family members understand and consistently apply the same rules and expectations. Kochi-ken are astute observers of human behavior and will quickly identify inconsistencies in family members' approaches, potentially leading to confusion or manipulation of different family members. Establishing clear, consistent leadership and rules that all family members enforce helps the dog understand their place within the family structure.

The breed's emotional sensitivity means they are deeply affected by family conflicts or stress. They may become withdrawn or anxious during periods of family tension, and their behavior can sometimes serve as a barometer for overall family harmony. Maintaining calm, positive interactions and providing extra reassurance during stressful times helps them cope with family difficulties and maintain their emotional stability.

During times of family change, such as moves, new additions to the household, or loss of family members, Kochi-ken require extra patience and support. Their deep emotional bonds mean they feel these changes intensely, and they may need time and assistance to adjust to new circumstances. Maintaining as much routine and consistency as possible during transitions, while providing extra attention and reassurance, helps them adapt more successfully to family changes.

Kochi-ken Health

The Kochi-ken is generally considered a hardy and healthy breed, benefiting from centuries of natural selection in challenging mountain environments that favored dogs with strong constitutions and genetic resilience. However, like all breeds, they are susceptible to certain health conditions that potential owners should understand and monitor throughout the dog's life. Their relatively small gene pool, common among rare breeds, requires careful attention to genetic diversity and health testing in breeding programs.

The breed's genetic health has been shaped by their historical isolation and the demanding conditions of their working environment. Dogs that could not maintain their health and vitality in the harsh mountain climate simply could not survive or reproduce, creating a natural selection pressure that favored robust health and longevity. This background contributes to the breed's overall hardiness, but modern breeding practices must carefully maintain this genetic strength while avoiding the problems that can arise from limited genetic diversity.

Musculoskeletal health is particularly important in Kochi-ken due to their active nature and athletic demands. Their strong, compact build generally serves them well, but like many medium-sized breeds, they can be susceptible to joint problems if not properly maintained. Regular exercise on appropriate surfaces, maintaining proper weight, and avoiding excessive stress on developing joints during puppyhood all contribute to long-term skeletal health. Their mountain heritage means they are generally well-adapted to vigorous physical activity, but sudden increases in exercise intensity should be avoided.

Cardiovascular health in the breed is generally excellent, reflecting their heritage as endurance athletes capable of working for hours in challenging terrain. However, like all dogs, they benefit from regular cardiovascular exercise to maintain heart health and proper circulation. Their deep chest and athletic build typically allow for excellent lung capacity and efficient oxygen utilization, making them well-suited to activities that require sustained physical effort.

The breed's double coat requires attention to skin health, particularly during seasonal shedding periods when the undercoat releases completely. Proper grooming during these times prevents matting and skin irritation, while regular brushing throughout the year maintains coat health and allows for early detection of skin problems. Their coat is generally resistant to common skin parasites, but regular inspection and appropriate preventive care are still essential.

Digestive health in Kochi-ken generally benefits from their hardy constitution, but their active nature and intelligent personality mean they require consistent, high-quality nutrition to maintain optimal health. Their working heritage suggests they evolved to efficiently utilize available nutrition, but modern dogs need carefully balanced diets that support their energy needs without leading to obesity. Their intelligence can sometimes lead to food-related behavioral issues if feeding routines are inconsistent or if they become bored with their diet.

Eye health deserves particular attention in the breed, as their keen vision was essential to their traditional hunting roles. Regular veterinary eye examinations can detect early signs of hereditary eye conditions that may affect some lines. Their alert, expressive eyes are typically clear and bright, and any changes in appearance or behavior that might indicate vision problems should be promptly evaluated by a veterinary professional.

The breed's neurological health generally reflects their intelligent, alert nature. However, their sensitive temperament means they can be affected by stress-related conditions if their mental and emotional needs are not properly met. Providing appropriate mental stimulation, maintaining consistent routines, and ensuring they have adequate opportunities for natural behaviors all contribute to neurological wellness and emotional stability.

Common Health Issues

  • Hip dysplasia - Genetic condition affecting hip joint development that can cause lameness and arthritis
  • Progressive retinal atrophy - Inherited eye condition that can lead to vision loss over time
  • Allergic dermatitis - Skin sensitivities that may develop due to environmental or food allergens

Recommended Health Testing

  • Hip and elbow radiographs - X-rays to evaluate joint development and detect dysplasia
  • Annual eye examinations by veterinary ophthalmologist - To screen for hereditary eye conditions
  • Genetic screening for breed-specific conditions - DNA tests for known hereditary issues in breeding lines
