Other Names & Breed Recognition

The Large Vendeen Griffon is the English translation of Grand Griffon Vendeen, the breed's official French name under which it is registered with the Federation Cynologique Internationale and other international registries. The name directly describes the breed's key characteristics: it is the largest of the Vendeen griffon breeds, it possesses the rough wire coat denoted by the term griffon, and it originates from the Vendee region of western France. The breed may also be referred to simply as the Grand Griffon Vendeen in English-speaking countries where the French name has been retained.

The Vendeen griffon family includes four related breeds of different sizes, all originating from the same region and sharing similar characteristics. The Grand Griffon Vendeen is the largest, followed by the Briquet Griffon Vendeen, the Grand Basset Griffon Vendeen, and the Petit Basset Griffon Vendeen. Of these four, the Petit Basset Griffon Vendeen is by far the most widely known internationally, while the Grand Griffon Vendeen remains one of the rarest, even within France.

Recognition of the Large Vendeen Griffon by international kennel clubs has been limited by the breed's small population and its concentration primarily within France. The FCI has granted full recognition, and the United Kennel Club has recognized the breed within its Scenthound Group. The breed is not currently recognized by the American Kennel Club, though it may be registered with the AKC's Foundation Stock Service as a preliminary step toward potential future recognition.

Despite its rarity, the Large Vendeen Griffon has a long and distinguished history as a hunting dog in France, and breed enthusiasts are working to preserve and promote this noble hound. The breed's small global population makes responsible breeding practices and international cooperation among breeders particularly important for maintaining genetic diversity and breed health.

Large Vendeen Griffon Organizations & Standards

The primary breed organization for the Large Vendeen Griffon is the Club du Griffon Vendeen in France, which oversees breed standards, breeding guidelines, and working tests for all four Vendeen griffon varieties. This club plays a critical role in preserving the breed's working characteristics, ensuring that breeding decisions prioritize functional ability alongside conformational correctness. The club maintains a studbook, coordinates health testing, and organizes field events that test the breed's hunting instincts and abilities.

The FCI breed standard for the Large Vendeen Griffon describes a large, well-constructed hound of distinguished and noble appearance. The standard emphasizes the breed's characteristic rough wire coat, which must be long, harsh, and bushy without being excessively woolly or silky. The breed's facial furnishings, including prominent eyebrows that shade the eyes without obscuring vision and a well-developed beard and mustache, are specifically noted as essential breed type features. The standard calls for a dog that moves with a free, easy, ground-covering gait suitable for prolonged hunting over difficult terrain.

Breeding guidelines established by the parent club emphasize the importance of maintaining the breed's dual identity as both a conformation dog and a functional hunting hound. Dogs used for breeding are expected to demonstrate hunting aptitude in addition to meeting the physical requirements of the breed standard. This emphasis on working ability helps prevent the breed from becoming purely an exhibition animal and preserves the behavioral traits that define its character.

Health testing protocols for the Large Vendeen Griffon typically include hip evaluations, eye examinations, and screening for breed-relevant conditions. Given the breed's small population, genetic diversity is a significant concern, and breeding programs may incorporate careful outcrosses and international breeding partnerships to maintain healthy genetic variation within the breed.

Large Vendeen Griffon Physical Description

The Large Vendeen Griffon is an imposing and noble hound that commands attention through its combination of size, substance, and distinctive rough coat. Males typically stand 24 to 27 inches at the shoulder and weigh between 66 and 77 pounds, while females are slightly smaller at 23 to 26 inches and 55 to 66 pounds. The overall impression is one of strength and elegance, with a well-proportioned frame that suggests endurance and capability rather than excessive bulk. The breed carries itself with a confident, dignified bearing that reflects its aristocratic French hunting heritage.

The head of the Large Vendeen Griffon is one of its most distinctive features, displaying the classic griffon expression created by prominent bushy eyebrows, a full beard, and a well-developed mustache. The skull is slightly domed with a well-defined occipital protuberance, and the muzzle is long, square, and strong, designed to carry game effectively. The eyes are large and dark, set beneath the expressive eyebrows with a lively and intelligent expression. The ears are set low, narrow, and fine in texture, folding inward and reaching well past the tip of the nose when drawn forward, a characteristic feature of French scenthound breeds.

The breed's rough wire coat is its most immediately recognizable physical characteristic and the feature that distinguishes it from smooth-coated hound breeds. The outer coat is long, coarse, and somewhat bushy, providing excellent protection against thorns, brambles, and rough vegetation encountered during hunting in the dense brush country of the Vendee. The undercoat is thick and dense, providing insulation against cold and wet weather. Accepted coat colors include white and orange, white and black, tricolor combinations, fawn with white markings, and black with tan markings, with various patterns and distributions of color permissible.

The body of the Large Vendeen Griffon is well-constructed for sustained physical effort, with a deep chest that provides ample lung capacity, well-sprung ribs, a strong level back, and muscular hindquarters that generate the propulsive power needed for all-day hunting. The legs are straight and well-boned, terminating in tight, well-padded feet with strong nails. The tail is thick at the base, carried in a gentle saber curve, and reaches approximately to the hock. The breed moves with a long, free, ground-covering stride that demonstrates its efficiency as a working hound.

Affectionate With Family
The Large Vendeen Griffon is a warmly affectionate breed that forms strong bonds with its family despite its independent hunting heritage. After a day of activity, this breed is content to settle near its people and enjoy their company, often seeking physical contact through leaning against legs or resting its head on a lap. The breed's affection is genuine and enthusiastic, expressed through tail wagging, happy vocalizations, and an eagerness to greet family members upon their return. While the Large Vendeen Griffon is not clingy or needy in its affection, it clearly values human companionship and is happiest when integrated into the daily life of its household.
Good With Young Children
The Large Vendeen Griffon is generally good-natured with children and can be a playful and entertaining companion for older kids. However, its large size and boisterous energy mean that interactions with very young children should be supervised to prevent accidental knockdowns or overly rough play. The breed does not have an aggressive temperament and is unlikely to intentionally harm a child, but its enthusiasm and physical exuberance can be overwhelming for toddlers and small children. Teaching children to respect the dog's space, particularly during mealtimes and rest periods, is important for harmonious coexistence.
Good With Other Dogs
Bred to work in large packs during hunting expeditions, the Large Vendeen Griffon has a natural sociability with other dogs that makes it well-suited to multi-dog households. This breed is generally friendly, tolerant, and cooperative with canine companions, and it often thrives when it has another dog to play and interact with. Pack dynamics are well understood by this breed, and serious aggression toward other dogs is uncommon. However, intact males may occasionally display competitive behavior with other intact males, and proper introductions should always be made when bringing a new dog into the household.
Shedding Level
The Large Vendeen Griffon sheds at a moderate level throughout the year, with some increase during seasonal transitions. The breed's rough, wire-haired coat does not shed as profusely as the smooth coats of many other hound breeds, but it does release loose hair consistently enough that regular grooming is needed to keep it under control. The coarse texture of the shed hair means it tends to cling to upholstery and clothing, making regular vacuuming and lint-rolling part of life with this breed. Overall, the shedding is manageable and should not be a significant concern for most owners who maintain a regular grooming routine.
Coat Grooming Frequency
The Large Vendeen Griffon's rough wire coat requires regular grooming attention to maintain its characteristic texture and prevent tangling. Brushing two to three times per week with a pin brush or slicker brush is recommended to remove dead hair, prevent mats from forming in the longer furnishings, and keep the coat looking tidy. The breed's facial hair, including the eyebrows and beard that give it its distinctive griffon expression, requires particular attention to keep clean and free of food debris. Hand-stripping may be needed periodically to maintain the proper coat texture, though many pet owners opt for a simpler maintenance routine.
Drooling Level
The Large Vendeen Griffon has a moderate tendency toward drooling, though it is not among the heaviest droolers in the hound world. Some drooling can be expected around mealtimes, after drinking water, and during periods of excitement or physical exertion. The breed's facial structure, including its moderately pendulous lips, contributes to occasional drool, and owners may want to keep a towel handy during feeding time. However, the drooling is generally not excessive enough to be a significant concern for most households and is far less than what one might experience with breeds known for heavy drooling.
Coat Type
The Large Vendeen Griffon possesses a distinctive rough, wire-haired coat that is one of the breed's defining physical characteristics. The outer coat is long, harsh, and slightly wavy, providing excellent protection against brambles, thorns, and rough vegetation encountered during hunting in the dense brush of the Vendee region. Beneath the outer coat lies a dense, insulating undercoat that provides warmth in cold and wet conditions. The breed's facial furnishings, including prominent bushy eyebrows and a full beard and mustache, give it a noble and somewhat shaggy appearance that is characteristic of the griffon type among French hound breeds.
Openness To Strangers
The Large Vendeen Griffon is generally approachable with strangers but may display initial caution before warming up. This breed is neither aggressive nor excessively suspicious of unfamiliar people, tending instead toward a measured friendliness that develops once the dog has had a chance to assess the situation. In social settings, the breed is typically well-mannered and willing to accept attention from new people, particularly if they approach calmly and allow the dog to initiate contact. Proper socialization from an early age helps ensure that the breed's natural caution does not develop into shyness or excessive wariness.
Playfulness Level
The Large Vendeen Griffon is an enthusiastically playful breed that retains a youthful exuberance well into adulthood. This breed genuinely enjoys interactive play and will eagerly engage in games of fetch, tug, and chase with its family members. Its hunting heritage contributes to a particularly strong drive for games that involve tracking, searching, and following scent trails, making scent-based games especially rewarding for this breed. The Large Vendeen Griffon's playful nature makes it an entertaining and engaging companion, though its size and energy level mean that play sessions can become boisterous and should be directed appropriately to prevent accidental damage to household items or injury to smaller family members.
Watchdog/Protective Nature
The Large Vendeen Griffon possesses a good voice and will bark to alert its family to the approach of visitors or unusual activity. Its deep, resonant hound bay is impressive and can serve as an effective deterrent to would-be intruders. However, the breed was developed as a hunting dog rather than a guard dog, and it lacks the territorial aggression and confrontational instinct of true protection breeds. A Large Vendeen Griffon is more likely to greet an intruder with tail wags after an initial barking announcement than to mount a physical defense. For families seeking an alert system rather than a guardian, this level of watchdog behavior is often ideal.
Adaptability Level
The Large Vendeen Griffon has specific needs that limit its adaptability to different living situations. This is a large, active breed that was bred to cover ground over rough terrain for extended periods, and it requires substantial space and exercise to remain physically and mentally healthy. Apartment living is generally not suitable for this breed, as it needs access to outdoor space and room to move. The breed's vocal nature, including its distinctive hound bay, can create difficulties in close-quartered living situations. The Large Vendeen Griffon also has a strong prey drive that requires a secure, fenced area for off-leash activity, as it will pursue interesting scents with single-minded determination.
Trainability Level
The Large Vendeen Griffon is an intelligent breed that is fully capable of learning complex commands but is famously independent and willful when it comes to obeying them. This breed was developed to work ahead of the hunter, making decisions independently while following scent trails through challenging terrain, and this self-reliance translates into a dog that does not feel compelled to comply with every request from its handler. Training requires exceptional patience, consistency, and creativity, as the Large Vendeen Griffon responds poorly to repetitive drills and harsh corrections. Positive reinforcement using high-value rewards, short and varied training sessions, and a sense of humor are essential tools for anyone training this breed.

Large Vendeen Griffon History & Development

The Large Vendeen Griffon traces its ancestry to the ancient hounds of western France, specifically the Vendee region along the Atlantic coast. This area, characterized by dense brush, rocky terrain, marshlands, and thick undergrowth, demanded a hunting dog with exceptional stamina, a keen nose, and a rough protective coat capable of withstanding the punishing landscape. The breed's origins likely extend back several centuries, with early ancestors believed to include the now-extinct white hounds of the French royal kennels and various rough-coated griffon-type dogs native to the region.

During the height of French pack hunting in the seventeenth and eighteenth centuries, the Large Vendeen Griffon was highly prized by the nobility for hunting large game including wild boar, deer, and wolves. The breed's exceptional scenting ability, tireless stamina, and bold temperament made it ideal for the demanding hunts that could last entire days across the rugged Vendeen countryside. The breed hunted in packs, with the deep, melodious baying voices of multiple hounds creating a chorus that allowed hunters on horseback to follow the progress of the chase from considerable distances.

The French Revolution and its aftermath brought significant disruption to the breeding programs of many French hound breeds, as the aristocratic kennels that had maintained them were disbanded or destroyed. The Large Vendeen Griffon survived this turbulent period through the efforts of dedicated breed enthusiasts in the Vendee region who continued to maintain small breeding populations. However, the breed's numbers declined significantly, and it never fully recovered to its pre-revolutionary population levels.

In the twentieth century, the breed standard was formalized, and organized efforts to preserve and promote the Large Vendeen Griffon were undertaken by French breed clubs. Despite these efforts, the breed remains one of the rarest of the French hound breeds, with a relatively small annual registration count even in France. The breed's demanding exercise requirements, strong hunting instincts, and independent temperament have limited its adoption as a companion dog, and it continues to be maintained primarily by hunting enthusiasts and dedicated breed preservationists.

Large Vendeen Griffon Temperament & Personality

The Large Vendeen Griffon possesses a temperament shaped by centuries of selective breeding for independent pack hunting in challenging terrain. The most prominent personality trait of this breed is its bold determination, a quality that served it well when pursuing large and potentially dangerous game such as wild boar through dense brush. In a domestic setting, this determination manifests as a dog with strong opinions and a willful streak that can be both endearing and challenging for owners who are not prepared for it.

Despite its strong-willed nature, the Large Vendeen Griffon is a genuinely friendly and sociable breed. Its pack-hunting heritage has instilled a natural comfort with social situations, and the breed generally gets along well with people, other dogs, and the general bustle of an active household. The breed has an exuberant, outgoing personality that can be infectious, and it approaches life with an enthusiasm and joie de vivre that reflects its French heritage. When the Large Vendeen Griffon is happy, everyone in the household knows it.

The breed's vocal nature is a characteristic that prospective owners must understand and accept. The Large Vendeen Griffon possesses a deep, resonant bay that it was bred to use while tracking game, and this vocalization carries over into domestic life. The breed will bay when excited, when alerting to visitors, when it catches an interesting scent, and sometimes seemingly just for the pleasure of hearing its own voice. While this is a charming trait in the field, it can be problematic in suburban or urban environments where noise levels are a concern.

The Large Vendeen Griffon is an intelligent dog with a strong independent streak that reflects its working heritage. This breed was developed to follow scent trails and make hunting decisions without constant direction from a handler, and it retains this self-reliance in all aspects of its life. The breed does not look to its owner for permission before acting and will follow its nose with single-minded determination when it catches an interesting scent. This independence means that the Large Vendeen Griffon is not a breed that lives to please its owner in the manner of retrievers or herding dogs, but it forms deep and genuine bonds with its family nonetheless.

Large Vendeen Griffon Family Life & Living Requirements

The Large Vendeen Griffon can be a wonderful family dog for the right household, but prospective owners must carefully consider whether their living situation and lifestyle can accommodate this breed's specific needs. This is a large, active, vocal hound that requires substantial space, significant daily exercise, and a secure outdoor environment. Families who enjoy an active outdoor lifestyle, have access to open spaces for the dog to explore, and appreciate the independent character of hound breeds will find the Large Vendeen Griffon a rewarding companion.

Housing requirements for the Large Vendeen Griffon strongly favor homes with large, securely fenced yards. The breed's powerful prey drive and exceptional nose mean that an interesting scent can override any training, making a solid, tall fence essential for off-leash outdoor time. Underground electronic fences are generally ineffective with this breed, as the drive to follow a scent can outweigh the correction. Apartment living is not appropriate for the Large Vendeen Griffon due to its size, exercise needs, and vocal tendencies, which would create difficulties for both the dog and its neighbors.

The breed's relationship with children is generally positive, as the Large Vendeen Griffon is good-natured and tolerant. However, its large size and exuberant personality mean that interactions with very small children should be supervised to prevent accidental injuries from the dog's enthusiastic play. Older children who can participate in the dog's exercise and training will find an eager and energetic companion. The breed's pack-oriented nature means it does well in multi-dog households and generally accepts new canine additions with grace.

Prospective owners should be aware that the Large Vendeen Griffon has a strong prey drive toward smaller animals including cats, rabbits, and other small pets. While some individuals can learn to coexist peacefully with cats they have been raised with from puppyhood, the breed's hunting instincts remain strong, and introductions to small animals should be conducted with extreme caution. Supervision is always recommended when the Large Vendeen Griffon is in the presence of small animals, regardless of the dog's prior behavior.

Large Vendeen Griffon Training & Exercise Needs

Training a Large Vendeen Griffon requires patience, creativity, and a willingness to accept that this breed will never offer the instant compliance of a Border Collie or a German Shepherd. The breed is intelligent and fully capable of understanding what is being asked, but its independent temperament means it will often weigh whether compliance serves its own interests before deciding to cooperate. This is not stubbornness born of stupidity but rather the calculated independence of a breed that was selected for centuries to make its own decisions in the field.

Positive reinforcement training methods are the only effective approach with the Large Vendeen Griffon. Harsh corrections, raised voices, and punitive methods will cause this sensitive breed to shut down, become defensive, or simply disengage from the training process. High-value food rewards are particularly effective motivators, as the breed is typically food-motivated. Training sessions should be kept short, varied, and interesting, as the Large Vendeen Griffon will lose interest quickly in repetitive drilling. Incorporating scent-based challenges and novel exercises keeps the breed engaged and willing to participate.

The exercise requirements of the Large Vendeen Griffon are substantial and non-negotiable. This breed was developed for all-day hunting expeditions across rugged terrain and possesses the stamina and drive to match. A minimum of 90 minutes to two hours of vigorous daily exercise is recommended, divided between structured activities such as long walks, hikes, or jogging and free-running time in a securely enclosed area. The breed excels at scent work, tracking trials, and other activities that engage its extraordinary nose, and these pursuits provide both physical exercise and essential mental stimulation.

Recall training deserves special emphasis with the Large Vendeen Griffon, as the breed's inclination to follow its nose can make reliable off-leash recall extremely difficult to achieve. Even well-trained individuals may become deaf to commands when they lock onto an interesting scent trail. For this reason, off-leash exercise should be limited to securely fenced areas, and the breed should always be walked on a leash or long line in unfenced environments. Investing in a sturdy harness designed for large, powerful dogs is advisable, as the breed can pull with considerable force when it catches a scent.

Large Vendeen Griffon Health Concerns

The Large Vendeen Griffon is generally a hardy and robust breed that benefits from the genetic diversity maintained within its working-dog breeding programs. The breed's average lifespan of 12 to 14 years is impressive for a dog of its size, as larger breeds typically have shorter lifespans than their smaller counterparts. However, like all breeds, the Large Vendeen Griffon is predisposed to certain health conditions that owners and breeders should monitor for throughout the dog's life.

Ear infections are among the most common health issues affecting the Large Vendeen Griffon, a consequence of the breed's long, pendulous ears that restrict airflow to the ear canal. The warm, moist environment created by the folded ear flap is an ideal breeding ground for bacteria and yeast. Without regular cleaning and monitoring, minor ear irritation can quickly progress to painful chronic infections that may require prolonged treatment with medicated drops or oral antibiotics. Preventive ear care should be a regular part of the grooming routine for every Large Vendeen Griffon.

Gastric dilatation-volvulus, commonly known as bloat, is a serious concern for the Large Vendeen Griffon due to its deep-chested conformation. This potentially fatal condition occurs when the stomach fills with gas and may twist on its axis, cutting off blood supply to the stomach and spleen. The onset of bloat is rapid and constitutes a veterinary emergency requiring immediate surgical intervention. Owners should familiarize themselves with the signs of bloat and implement preventive feeding practices to reduce risk.

Hip dysplasia affects the Large Vendeen Griffon at rates consistent with other large-breed dogs and should be screened for through radiographic evaluation of all breeding stock. The condition can range from mild, causing occasional stiffness, to severe, resulting in chronic pain and significant mobility limitations. Maintaining a healthy weight, providing appropriate exercise, and supporting joint health through supplementation can help manage the condition and maintain the dog's quality of life. Additional health concerns include hypothyroidism, epilepsy, and various skin conditions related to the breed's dense wire coat.

Common Health Issues

  • Hip Dysplasia - A common orthopedic condition in large breeds where the hip joint develops abnormally, leading to instability, pain, and progressive arthritis. The Large Vendeen Griffon's active lifestyle can exacerbate symptoms if the condition is present, making early screening and weight management important preventive strategies.
  • Ear Infections (Otitis Externa) - The Large Vendeen Griffon's long, pendulous ears create a warm, moist environment within the ear canal that is conducive to bacterial and yeast infections. Regular ear cleaning and inspection are essential to catch and address infections early before they become chronic or painful.
  • Epilepsy - Idiopathic epilepsy, characterized by recurring seizures without an identifiable underlying cause, has been reported in the breed. The condition typically manifests between one and five years of age and can usually be managed effectively with anticonvulsant medication under veterinary supervision.
  • Hypothyroidism - An underactive thyroid gland can lead to metabolic slowdown in the Large Vendeen Griffon, presenting as unexplained weight gain, lethargy, coat deterioration, and skin problems. The condition is diagnosed through blood testing and is manageable with daily thyroid hormone replacement therapy.
  • Gastric Dilatation-Volvulus (Bloat) - As a large, deep-chested breed, the Large Vendeen Griffon is at elevated risk for this life-threatening condition in which the stomach fills with gas and may twist on its axis. Preventive measures include feeding multiple smaller meals rather than one large meal, using slow-feeder bowls, and avoiding vigorous exercise immediately before and after eating.
  • Patellar Luxation - A condition in which the kneecap slides out of its normal position, causing intermittent lameness and discomfort. While more commonly associated with smaller breeds, it can occur in the Large Vendeen Griffon and may require surgical correction in severe cases.
  • Dermatitis - The breed's dense wire coat can trap moisture and debris close to the skin, potentially leading to contact dermatitis or allergic skin reactions. Regular grooming and coat maintenance help minimize this risk, and any persistent skin irritation should be evaluated by a veterinarian.

Preventive Care & Health Monitoring

  • Ear Care and Monitoring - Clean the Large Vendeen Griffon's ears weekly using a veterinarian-recommended ear cleaning solution to remove wax buildup and moisture. Check for signs of redness, odor, or discharge that may indicate an infection. Keep the hair around the ear canal trimmed to improve air circulation and reduce the warm, moist conditions that promote bacterial and yeast growth.
  • Joint Health Support - Maintain a healthy weight throughout the dog's life to reduce stress on joints and lower the risk of hip dysplasia and arthritis. Consider joint-supporting supplements such as glucosamine, chondroitin, and omega-3 fatty acids, particularly as the dog ages. Avoid high-impact exercise during the growth period in puppies to protect developing joints.
  • Bloat Prevention Protocol - Feed the Large Vendeen Griffon two to three smaller meals throughout the day rather than one large meal. Use a slow-feeder bowl to prevent rapid eating. Avoid strenuous exercise for at least one hour before and after meals. Learn to recognize the early signs of bloat, including unproductive retching, abdominal distension, and restlessness, and seek emergency veterinary care immediately if these symptoms appear.
  • Coat and Skin Maintenance - Brush the wire coat thoroughly two to three times per week to remove dead hair, prevent matting, and allow air to reach the skin. Inspect the skin during grooming sessions for signs of irritation, parasites, or hot spots. After outdoor activities in brush or tall grass, check the coat and skin for ticks, burrs, and foxtails that may become embedded.
  • Dental Hygiene - Brush the dog's teeth at least three times per week using a canine-specific toothpaste and toothbrush. Provide dental chews approved by the Veterinary Oral Health Council to supplement brushing. Schedule professional dental cleanings as recommended by your veterinarian, typically annually, to address plaque and tartar buildup that home care cannot reach.

Large Vendeen Griffon Grooming & Maintenance

The Large Vendeen Griffon's rough wire coat is both one of its most attractive features and one of its most demanding maintenance requirements. The coat's coarse texture was developed to protect the dog during hunts through dense, thorny undergrowth, and while it serves this purpose admirably, it also requires consistent grooming attention to remain in good condition. A thorough brushing two to three times per week using a pin brush, slicker brush, or a combination of both is necessary to remove dead hair, prevent mats and tangles, and maintain the coat's characteristic rough texture.

The breed's distinctive facial furnishings require special attention during grooming. The bushy eyebrows, full beard, and mustache that give the Large Vendeen Griffon its expressive appearance can trap food debris, dirt, and moisture, creating both hygiene issues and potential skin irritation if not cleaned regularly. Wiping the beard after meals and checking the facial hair for tangles or debris should be part of the daily routine. The eyebrows should be maintained at a length that does not obstruct the dog's vision while preserving the breed's characteristic expression.

Hand-stripping is the preferred method for maintaining the proper texture of the Large Vendeen Griffon's wire coat. This process involves pulling out dead outer coat hairs by hand or with a stripping knife, which encourages the growth of new, correctly textured coat. Hand-stripping preserves the coat's natural harshness and weather-resistant properties in a way that clipping does not. However, hand-stripping is time-consuming and requires skill, and many pet owners choose to use a professional groomer for this task or opt for a combination approach that includes occasional clipping with periodic hand-stripping.

Beyond coat care, the Large Vendeen Griffon requires regular attention to its ears, nails, teeth, and feet. The long, pendulous ears should be cleaned weekly and inspected for signs of infection. Nails should be trimmed every two to three weeks to prevent overgrowth that can affect the dog's gait and cause discomfort. Dental care should include regular brushing with a canine toothpaste and periodic professional cleanings. The feet should be checked after outdoor excursions for embedded debris, cracked pads, or overgrown hair between the toes that may need trimming.
