Other Names & Breed Recognition

The Kooiker Dog is an informal English-language name for the breed officially known as the Nederlandse Kooikerhondje. The full Dutch name translates roughly to Dutch decoy dog, reflecting the breed's historical role in the traditional Dutch duck trapping system known as the eendenkooi. The breed is also referred to simply as the Kooikerhondje, the Kooiker Hound, or the Dutch Decoy Dog in various English-speaking contexts. The shortened name Kooiker Dog has gained currency among enthusiasts who find the full Dutch name challenging to pronounce or spell.

The breed's name derives directly from the profession of its original handlers. A kooiker was the person who operated a duck decoy, an elaborate system of channels and screens used to lure and capture wild ducks for market or banding. The kooiker's dog played an essential role in this operation, using its bushy, white-tipped tail and playful movements to attract the curiosity of ducks and lure them into the funnel-shaped traps. The word hondje simply means little dog in Dutch, and the full name thus describes the little dog of the duck decoy operator.

In terms of formal recognition, the breed is registered under its official Dutch name across all major kennel clubs. The American Kennel Club admitted the breed to its Sporting Group in 2018, bringing increased visibility to the breed in the United States. The Federation Cynologique Internationale, the United Kennel Club, the Kennel Club in the United Kingdom, and the Canadian Kennel Club all recognize the breed as well. Regardless of which name is used in casual conversation, the breed standards across these organizations describe the same charming, orange-red and white sporting dog.

The variety of names used for this breed reflects its growing international popularity and the challenges that non-Dutch speakers face with the original Dutch nomenclature. Whether called the Kooiker Dog, the Kooikerhondje, or the Nederlandse Kooikerhondje, the breed's identity remains rooted in its unique Dutch heritage and its centuries-old role as the duck decoy operator's indispensable companion.

Kooiker Dog Organizations & Standards

The primary breed standard for the Kooiker Dog is maintained by the Raad van Beheer, the Dutch Kennel Club, which serves as the breed's country-of-origin registry. The Dutch standard provides the definitive description of the ideal Kooiker Dog, emphasizing its well-proportioned, nearly square build, its distinctive orange-red and white parti-color coat, and its characteristic black-tipped ear feathering known as earrings. This standard forms the basis for the FCI standard, which is adopted by kennel clubs in FCI member countries worldwide.

The American Kennel Club recognized the breed in 2018, placing it in the Sporting Group. The AKC standard closely follows the FCI standard and describes a small, well-balanced sporting dog with a cheerful expression and a flowing, feathered coat. The breed's entry into the AKC has significantly increased its visibility in the United States and provided American breeders and exhibitors with access to the full range of AKC events and programs.

The United Kennel Club classifies the Kooiker Dog in its Gun Dog group, while the Kennel Club in the United Kingdom places it in the Gundog group. The Canadian Kennel Club includes the breed in its Sporting Dogs group. Across all of these registries, the breed standard consistently emphasizes the same key features: the distinctive orange-red and white coat pattern, the black-tipped ear feathering, the well-plumed tail carried level with or slightly above the topline, and the alert, friendly expression that characterizes the breed.

The Nederlandse Kooikerhondje Club, founded in the Netherlands, serves as the breed's primary parent club and plays a central role in coordinating breeding efforts, maintaining health databases, and promoting the breed internationally. National breed clubs have also been established in the United States, the United Kingdom, Canada, and several other countries. These organizations provide resources for prospective owners, support responsible breeding practices, and organize breed-specific events that help maintain the quality and health of the Kooiker Dog population worldwide.

Kooiker Dog Physical Description

The Kooiker Dog is a small to medium-sized sporting breed that presents an attractive, well-balanced silhouette with a distinctly cheerful and alert bearing. Males typically stand 15 to 17 inches at the shoulder, while females measure 14 to 16 inches. Weight ranges from 20 to 30 pounds, with the breed's build conveying an impression of athleticism and agility rather than heaviness. The body is nearly square in proportion, with a level topline, a moderately deep chest, and well-sprung ribs that provide ample lung capacity for an active sporting dog.

The breed's coat is one of its most striking features. The medium-length hair ranges from straight to slightly wavy and consists of a protective outer coat over a well-developed, soft undercoat. The color is always orange-red on a white background, with clearly defined patches that give the breed its distinctive parti-color appearance. The feathering on the ears, chest, legs, and tail adds elegance to the breed's outline. The most prized coat feature is the black-tipped ear feathering, called earrings, which frames the face beautifully and is considered a hallmark of breed type.

The head is moderately broad with a slight dome, a well-defined stop, and a muzzle that tapers gently without appearing snipey. The eyes are almond-shaped, dark brown, and convey an expression of intelligence and warmth. The ears are set moderately high and hang close to the cheeks, with their length reaching approximately to the corner of the mouth. The nose is black, and the jaw supports a complete scissors bite.

The tail is one of the Kooiker Dog's most functionally important features, given the breed's history as a duck decoy dog. It is set as an extension of the topline, well-feathered with a luxurious white plume, and carried level with or slightly above the back in a gentle curve when the dog is alert or in motion. The waving white plume of the tail was the primary tool used by the kooiker's dog to attract the attention of curious ducks in the decoy system. The legs are straight, well-boned, and muscular, ending in compact, well-padded feet that provide sure footing on varied terrain.

Affectionate With Family
The Kooiker Dog is deeply devoted to its family and forms strong, lasting bonds with the people it lives with. This breed thrives on close companionship and is happiest when it can participate in daily family activities. Kooiker Dogs are known for following their owners from room to room, always seeking proximity without being overly demanding. Their affection is genuine and consistent, expressed through gentle leaning, soft eye contact, and an ever-wagging tail that signals their contentment in the presence of their loved ones.
Good With Young Children
The Kooiker Dog can be a good companion for children, but it tends to do best with older children who understand how to interact respectfully with dogs. The breed is not typically aggressive, but its somewhat sensitive and reserved nature means it may become overwhelmed by the unpredictable movements and loud noises associated with very young children. Kooiker Dogs that are raised alongside children from puppyhood tend to be more tolerant, though supervision is always recommended. Teaching children to approach the dog calmly and to respect its space helps foster a positive relationship.
Good With Other Dogs
Kooiker Dogs are generally sociable with other dogs and enjoy the companionship of canine housemates. Their sporting heritage gives them a cooperative nature that translates well to multi-dog households. They tend to be playful and engaging with dogs of similar size and energy level, and they rarely display the kind of serious dog-directed aggression seen in some other breeds. Proper socialization during the critical developmental period helps ensure that the Kooiker Dog remains confident and friendly in canine social situations, whether at home or in public.
Shedding Level
The Kooiker Dog sheds moderately throughout the year, with noticeable increases during seasonal coat changes in spring and fall. The breed's medium-length coat with its developed undercoat means that regular shedding management is a necessary part of ownership. Owners should expect to find orange-red and white hairs on furniture, clothing, and floors. Consistent brushing helps manage loose hair significantly, but prospective owners should be prepared for a moderate level of shedding as an ongoing reality of living with this breed.
Coat Grooming Frequency
The Kooiker Dog's coat requires regular but not excessive grooming to maintain its attractive appearance and healthy condition. Brushing two to three times per week is recommended to prevent matting, remove loose hair, and keep the coat looking its best. The feathering on the ears, chest, legs, and tail can be prone to tangling and may require more focused attention. During heavy shedding periods, daily brushing sessions help manage the increased hair loss. The coat has a natural water-resistant quality and should not be over-bathed, as excessive washing strips the coat's protective oils.
Drooling Level
The Kooiker Dog is not a drooling breed. Its well-proportioned muzzle and tight lip structure produce virtually no excess saliva under normal conditions. Owners can enjoy interacting with their Kooiker Dog without concern about drool on hands, clothing, or furniture. This clean-mouthed quality is appreciated by those who prefer a tidy companion. As with any breed, sudden or unusual drooling could be a sign of a health concern such as dental problems or nausea and should be evaluated by a veterinarian.
Coat Type
The Kooiker Dog has a medium-length coat that ranges from slightly wavy to straight, with a well-developed soft undercoat beneath a longer, protective outer coat. The coat's crowning feature is the beautiful feathering found on the ears, chest, front and hind legs, and the luxurious plume of the tail. The ear feathering often features distinctive black tips, known as earrings, which are a highly prized breed characteristic. The coat is naturally water-resistant, reflecting the breed's heritage as a working duck dog in the wetlands of the Netherlands.
Openness To Strangers
The Kooiker Dog is typically reserved and cautious with unfamiliar people, a trait that is well-documented in the breed standard and considered characteristic of the breed. This reserve should not be mistaken for fearfulness or aggression; rather, the Kooiker Dog simply takes its time assessing new people before deciding to engage. Some individuals may be quite shy with strangers if not adequately socialized during puppyhood. Early, extensive, and positive socialization is critical for this breed to develop the confidence needed to navigate encounters with unfamiliar people without undue stress.
Playfulness Level
The Kooiker Dog is a playful and enthusiastic breed that retains its sporting instincts in a cheerful, family-friendly package. These dogs love interactive games, including fetch, hide-and-seek, and retrieving objects from water. Their intelligence makes them natural candidates for puzzle toys and problem-solving activities that challenge them mentally while satisfying their need for engagement. The Kooiker Dog's playfulness is balanced by an ability to settle when playtime is over, a quality that makes them enjoyable companions who know when to shift from active play to relaxed companionship.
Watchdog/Protective Nature
The Kooiker Dog's natural alertness and reserved attitude toward strangers make it an effective watchdog for its size. This breed is quick to notice changes in its environment and will readily alert its family to the approach of visitors or unusual activity with a clear, purposeful bark. The Kooiker Dog takes its sentinel duties seriously without becoming a nuisance barker, generally distinguishing between genuine alerts and everyday occurrences. While it lacks the physical presence to serve as a guard dog, its attentiveness and vocal warnings make it a reliable early warning system.
Adaptability Level
The Kooiker Dog adapts well to a variety of living environments, provided its needs for exercise, mental stimulation, and companionship are met. While the breed does well in homes with fenced yards where it can run and play, it can also thrive in an apartment setting if given sufficient daily exercise and outdoor time. The Kooiker Dog adjusts to different routines and schedules with reasonable ease, though it does not tolerate prolonged periods of isolation. Transitions to new homes or environments are generally handled well by this breed when managed with patience and consistency.
Trainability Level
The Kooiker Dog is an intelligent and willing learner that responds exceptionally well to positive reinforcement training methods. The breed's sporting heritage has endowed it with a natural desire to work cooperatively with its handler, and this cooperative spirit shines during training sessions. Kooiker Dogs excel in a variety of canine sports and activities, including obedience, agility, rally, and scent work. Their sensitivity demands a gentle, encouraging approach, as harsh corrections can damage the trust between dog and handler and undermine the training process. Consistency, patience, and generous use of rewards produce a well-trained and confident Kooiker Dog.

Kooiker Dog History & Development

The Kooiker Dog's history stretches back several centuries in the Netherlands, where it was developed as an essential working partner in the traditional Dutch duck decoy system known as the eendenkooi. This ingenious trapping method, which dates to at least the 16th century, used a series of curved, narrowing channels screened by reed fencing to lure wild ducks from open water into netted traps. The kooiker, or decoy operator, relied on his small, orange-red and white dog to attract the ducks' attention with its bushy, waving tail and playful movements along the edges of the channels.

The breed appears in numerous Dutch paintings from the 17th and 18th centuries, depicted alongside hunters and in domestic scenes that attest to its dual role as a working dog and a beloved companion. Rembrandt, Jan Steen, and other Dutch Golden Age artists featured small orange-red and white dogs that closely resemble the modern Kooiker Dog, providing valuable visual documentation of the breed's appearance and role during this period. The breed's association with Dutch culture runs deep, and legend holds that a Kooiker Dog belonging to William of Orange alerted him to an assassination attempt by the Spanish, earning the breed a place in national folklore.

By the early 20th century, the traditional duck decoy system had fallen into decline, and with it the population of Kooiker Dogs dwindled to dangerously low numbers. By the time of World War II, the breed was on the verge of extinction. The survival and recovery of the Kooiker Dog is largely credited to Baroness Van Hardenbroek van Ammerstol, who undertook a determined effort in the 1940s to locate surviving examples of the breed. She sent peddlers into the Dutch countryside with a photograph of the breed, and the dogs they eventually located became the foundation of the modern breeding program.

From this critically narrow genetic base, the breed was carefully rebuilt through disciplined breeding practices. The Dutch Kennel Club officially recognized the breed in 1971, and the Kooiker Dog gradually gained admirers beyond the Netherlands. International recognition followed over the decades, culminating in the breed's admission to the American Kennel Club's Sporting Group in 2018. Despite its growing popularity, the Kooiker Dog remains relatively uncommon worldwide, and responsible breeders continue to prioritize genetic health and breed type in their programs.

Kooiker Dog Temperament & Personality

The Kooiker Dog possesses a temperament that blends the working drive of a sporting breed with the warmth and sensitivity of a devoted companion. These dogs are cheerful, good-natured, and attentive to their families, displaying a quiet confidence that makes them pleasant to live with. The breed is known for its calm indoor demeanor, a quality that stands in contrast to its lively enthusiasm during outdoor activities and play sessions. This ability to shift between active engagement and relaxed companionship is one of the Kooiker Dog's most appealing characteristics.

Intelligence is a defining trait of the Kooiker Dog, and it manifests in the breed's keen observational skills and quick learning ability. These dogs are adept at reading their owners' body language and vocal cues, often anticipating commands before they are given. This sensitivity to human communication makes the Kooiker Dog an exceptionally responsive companion, but it also means the breed can be affected by tension or discord within the household. A stable, harmonious home environment brings out the best in the Kooiker Dog's temperament.

The breed's characteristic reserve with strangers is an important aspect of its personality that prospective owners should understand. Kooiker Dogs are not typically outgoing or effusive with unfamiliar people and may initially hold back when meeting new acquaintances. This caution is deeply ingrained in the breed's temperament and is recognized in the breed standard. While extensive early socialization can help build confidence and reduce excessive shyness, the Kooiker Dog will generally never become the kind of dog that enthusiastically greets every stranger it encounters. This reserve should be respected as a breed trait rather than viewed as a flaw.

With their own family, however, Kooiker Dogs are affectionate, loyal, and deeply engaged companions. They form strong bonds with their primary caregivers and enjoy participating in all aspects of daily life. Their sporting heritage gives them an enthusiasm for outdoor activities, and they particularly enjoy games that tap into their natural retrieving and scenting instincts. The Kooiker Dog's combination of intelligence, sensitivity, and devotion creates a companion that is both rewarding and demanding in equal measure, requiring an owner who appreciates and nurtures the breed's unique qualities.

Kooiker Dog Family Life & Living Requirements

The Kooiker Dog integrates well into family life when its needs for companionship, exercise, and mental stimulation are met consistently. This breed is at its best in a home where it is treated as a full member of the family and included in daily activities. Kooiker Dogs that are relegated to the backyard or excluded from family life often develop behavioral issues rooted in anxiety and boredom. The breed's strong need for human connection means it is best suited to households where someone is home for a significant portion of the day or where arrangements can be made to prevent extended periods of isolation.

A home with a securely fenced yard is ideal for the Kooiker Dog, providing a safe space for off-leash play and exploration. The breed has enough sporting instinct to investigate interesting scents and may wander if given the opportunity, so reliable fencing is important. That said, the Kooiker Dog can adapt to apartment living if it receives adequate daily exercise and outdoor time. The breed's moderate size and calm indoor demeanor make it more adaptable to smaller living spaces than many sporting breeds of similar energy level.

Families with children should be aware that the Kooiker Dog's sensitive temperament pairs best with older, more considerate children who can respect the dog's boundaries and interact with it calmly. The breed is not prone to aggression, but it may become stressed or withdrawn if subjected to rough handling, loud environments, or chaotic interactions. Households that maintain a reasonably calm atmosphere and teach children appropriate dog-handling skills will find the Kooiker Dog to be a delightful family companion that bonds closely with each member of the household.

The Kooiker Dog typically gets along well with other dogs, especially when raised together or properly introduced. Its sporting heritage gives it a cooperative disposition that facilitates harmonious multi-dog households. The breed retains some prey drive, so caution is warranted around very small pets such as hamsters or pet birds. Cats and Kooiker Dogs often coexist peacefully when the dog has been raised with feline housemates from a young age, though individual temperament and the cat's disposition play significant roles in the success of the relationship.

Kooiker Dog Training & Exercise Needs

The Kooiker Dog is a highly trainable breed that responds beautifully to positive reinforcement methods. Its intelligence, cooperative nature, and desire to please its handler make training an enjoyable and productive endeavor for both dog and owner. The breed excels in a variety of canine sports and activities, including obedience, agility, rally, flyball, scent work, and dock diving. Many Kooiker Dogs also show aptitude for therapy work, where their gentle demeanor and sensitivity to human emotions are particularly valued.

Training should begin early and be conducted with consistent, gentle methods that build the dog's confidence while establishing clear expectations. The Kooiker Dog's sensitivity means that harsh corrections, raised voices, or confrontational training techniques are counterproductive and can cause lasting damage to the dog's trust in its handler. Instead, rewards-based training using food, praise, and play produces a Kooiker Dog that is eager to learn and enthusiastic about working with its owner. Short, varied training sessions that keep the dog mentally engaged yield better results than long, repetitive drills.

The breed's exercise needs fall in the moderate to high range, reflecting its sporting heritage. A Kooiker Dog benefits from at least 60 minutes of physical activity daily, which can be broken into multiple sessions. This exercise should include a mix of leashed walks, off-leash play in secure areas, and activities that engage the dog's mind as well as its body. Fetch, swimming, and interactive play are particularly well-received by the breed. The Kooiker Dog also enjoys nose work and tracking activities that tap into its natural scenting abilities.

Mental stimulation is equally important to the Kooiker Dog's well-being. This intelligent breed needs regular mental challenges to prevent boredom and the behavioral problems that accompany it. Puzzle feeders, training games, scent-detection exercises, and interactive toys all help keep the Kooiker Dog's active mind occupied. A Kooiker Dog that receives adequate physical exercise and mental enrichment is a calm, content, and well-behaved household companion, while one that is under-stimulated may channel its energy into undesirable behaviors such as excessive barking, digging, or destructive chewing.

Kooiker Dog Health Concerns

The Kooiker Dog is generally a healthy breed with a life expectancy of 12 to 15 years, but its history of near-extinction and subsequent population bottleneck has left it with several hereditary health conditions that prospective owners and breeders must take seriously. The most significant of these is hereditary necrotising myelopathy, a fatal neurological disease that is unique to the Kooikerhondje breed. ENM causes rapid deterioration of the spinal cord in affected dogs, typically presenting in young animals and progressing quickly to paralysis and death. Fortunately, a reliable DNA test is available, and responsible breeders use it to ensure that two carriers are never bred together.

Von Willebrand disease is another important hereditary condition in the Kooiker Dog. This bleeding disorder results from a deficiency in the von Willebrand clotting factor and can cause prolonged bleeding from injuries, during surgery, or from heat cycles in females. DNA testing allows breeders to identify carriers and affected dogs, and the availability of this test has made it possible to significantly reduce the incidence of the disease through informed breeding decisions. Prospective owners should verify that the parents of any puppy they consider have been tested clear or are known carriers bred only to clear partners.

Orthopedic issues, particularly patellar luxation, occur in the breed with some regularity. The kneecap displacement can range from an occasional, self-correcting slip to a chronic condition that causes pain and lameness and requires surgical repair. Maintaining the Kooiker Dog at a healthy weight and providing appropriate exercise on supportive surfaces helps minimize orthopedic stress. Eye conditions, including cataracts, have also been documented in the breed and should be monitored through regular ophthalmologic examinations.

Epilepsy and polymyositis represent additional health concerns that have been identified in the Kooiker Dog population. Epilepsy manifests as recurrent seizures that can often be managed with medication, while polymyositis is an inflammatory muscle condition that requires immunosuppressive treatment. The relatively small gene pool of the Kooiker Dog means that health monitoring and responsible breeding practices remain critically important to the breed's long-term genetic health. Prospective owners should seek breeders who conduct comprehensive health testing, participate in breed health registries, and make breeding decisions that prioritize the well-being of the breed as a whole.

Common Health Issues

  • Von Willebrand Disease - A hereditary bleeding disorder caused by a deficiency in von Willebrand factor, a protein essential for blood clotting. The Kooiker Dog has a known predisposition to this condition, and responsible breeders test for it before breeding. Affected dogs may experience prolonged bleeding from injuries, surgeries, or even minor wounds.
  • Hereditary Necrotising Myelopathy (ENM) - A fatal neurological disease specific to the Kooikerhondje breed in which the spinal cord deteriorates rapidly. Onset typically occurs in young dogs, and there is no cure. A DNA test is available, and ethical breeders screen all breeding stock to ensure that carriers are not bred to one another, which has significantly reduced the incidence of this devastating condition.
  • Patellar Luxation - A condition in which the kneecap dislocates from its normal position in the femoral groove. The Kooiker Dog can be affected by this orthopedic issue, which ranges from mild, intermittent displacement to chronic dislocation requiring surgical intervention. Maintaining a healthy weight and providing appropriate exercise help minimize stress on the knee joints.
  • Cataracts - An opacity of the lens of the eye that can impair vision and, in severe cases, lead to blindness. Cataracts can develop at various ages in the Kooiker Dog and may be hereditary or age-related. Regular ophthalmologic examinations help detect cataracts early, and surgical removal is possible for cases that significantly affect quality of life.
  • Epilepsy - Idiopathic epilepsy has been reported in the Kooiker Dog breed. Affected dogs experience recurrent seizures that may vary in frequency and severity. While the condition cannot be cured, it can often be managed effectively with anticonvulsant medications prescribed by a veterinarian. Careful record-keeping of seizure frequency and duration helps guide treatment decisions.
  • Polymyositis - An inflammatory condition of the muscles that can cause weakness, pain, and muscle wasting. The Kooiker Dog has been identified as having a breed predisposition to this autoimmune disorder. Diagnosis involves blood tests, electromyography, and muscle biopsy, and treatment typically includes immunosuppressive medications to control the inflammatory response.

Preventive Care & Health Monitoring

  • Genetic Health Testing - Before acquiring a Kooiker Dog, verify that the breeder has tested for von Willebrand disease and hereditary necrotising myelopathy using available DNA tests. These tests are essential for responsible breeding in this breed and should be non-negotiable when selecting a puppy. Request documentation of test results for both parents.
  • Regular Veterinary Examinations - Schedule biannual wellness visits to monitor for early signs of patellar luxation, eye disorders, and other breed-predisposed conditions. Annual ophthalmologic examinations are particularly important for early detection of cataracts. Keep vaccination and parasite prevention protocols current as recommended by your veterinarian.
  • Joint Health Maintenance - Maintain the Kooiker Dog at a healthy body weight to reduce stress on joints and minimize the risk of patellar luxation. Provide joint-supporting supplements such as glucosamine and chondroitin as recommended by your veterinarian. Avoid high-impact activities during the growth phase to protect developing joints.
  • Coat and Skin Care - Brush the coat two to three times weekly to prevent matting, particularly in the feathered areas. Inspect the skin regularly for signs of irritation or parasites. Maintain a regular flea and tick prevention program, as the Kooiker Dog's outdoor activities increase its exposure to external parasites.
  • Dental Care - Implement a daily tooth-brushing regimen using canine-appropriate toothpaste. Supplement with dental chews and schedule professional dental cleanings as recommended by your veterinarian. Consistent dental care helps prevent periodontal disease and its associated systemic health risks.

Kooiker Dog Grooming & Maintenance

The Kooiker Dog's medium-length, feathered coat requires regular grooming attention but is less demanding than the coats of many other sporting breeds. The breed's coat has a natural, slightly tousled quality that is part of its charm, and excessive trimming or sculpting is neither necessary nor desirable. The goal of grooming the Kooiker Dog is to maintain the coat's health and natural appearance while preventing matting and managing shedding.

Brushing two to three times per week with a slicker brush or pin brush is the foundation of the Kooiker Dog's grooming routine. Pay particular attention to the feathering behind the ears, on the chest, along the backs of the legs, and on the tail, as these areas are most prone to tangling and mat formation. A metal comb worked through the feathering after brushing helps catch any remaining tangles. During seasonal shedding periods in spring and fall, daily brushing is advisable to manage the increased volume of loose hair and prevent it from accumulating around the home.

Bathing should be performed on an as-needed basis, typically every six to eight weeks or when the dog becomes noticeably dirty. The Kooiker Dog's coat has a natural water-resistant quality that helps repel dirt and debris, and over-bathing can strip these protective oils and leave the coat dry and dull. When bathing is necessary, a gentle, pH-balanced dog shampoo followed by a light conditioner on the feathered areas helps maintain coat health and manageability.

Ear care is particularly important for the Kooiker Dog, as the breed's hanging ears can trap moisture and create conditions favorable to bacterial or yeast infections. Inspect the ears weekly and clean them with a veterinarian-recommended ear cleaning solution as needed. Nail trimming should be performed every two to three weeks or as needed to prevent overgrowth and associated discomfort. Dental care rounds out the maintenance routine and should include daily tooth brushing with a canine-specific toothpaste, supplemented by dental chews and regular professional cleanings to maintain oral health throughout the dog's life.
