Medium Size Poodle
The medium-sized Kai Ken, also known as Kai Inu, Tora Inu, or Kai tora-ken, is part of the Asian Spitz group and primarily kept as a hunting dog in its homeland of Japan. Due to an export ban since 1934, this dominant and spirited Japanese breed is a rare exotic in other countries.

The striped Kai Ken has an insatiable urge to hunt and move about.
The medium-sized Kai appears impressive with its even-toned, muscular body. Strong and swift, some members of the breed can even climb trees thanks to their well-developed legs and hocks.
The FCI (Fédération Cynologique Internationale) recognises the Kai Ken under standard number 317, classifying it among the Asian Spitz breeds. Typical for this group, the Kai has a pointed face, triangular, erect ears, and a densely furred, high-set tail that it carries curled or sickle-shaped over its back.
Male Kai Ken reach a shoulder height of about 53cm. Females are slightly smaller, averaging 48cm. The FCI standard does not specify the weight, but it should be proportionate to the body size, generally around 18kg.
The Kai Ken’s distinctive brindle coat has been preserved over millennia without crossbreeding with other breeds. The fur comes in black, red, and black-red brindle colours.
Good to know: The typical brindle pattern develops only after approx. one year. In the first twelve months, the puppy’s fur is solid-coloured.
The adult Kai Ken’s fur is hard and strong, featuring a soft, dense undercoat. This provides excellent protection against the often extreme climate of its mountainous homeland.
The Kai is a very primitive dog, retaining its instinctive, ‘wild’ nature. Its pronounced hunting instinct, high alertness, natural pack behaviour, and selective obedience are typical traits.
It is known as a dominant and independent hunter that seldom sees the need for unconditional human follow.
On the flip side, the Kai can also be a very loyal and alert dog, standing protectively by its family. Once you have earned the Kai Inu’s trust, its initial wariness towards strangers gives way to a very friendly and affectionate nature. The dog revels in love and attention. However, its strong hunting passion and natural sharpness should never be underestimated. These traits are intrinsic to its nature and always simmer beneath the surface.
The Kai is demanding and challenging, suited for lovers of sports and work. Due to its primitive character, it’s not necessarily recommended as a family dog.
Determined to keep a Kai as a family dog? Be aware that its high exercise requirements and especially its training and socialisation needs are extremely time-intensive.
Training a Kai Ken requires much experience, patience, and consistency to transform this highly intelligent and eager, yet dominant dog into a well-adjusted companion.
Motivating the Kai to cooperate also demands creativity, especially when it’s kept as a companion dog without hunting duties. This highly intelligent dog craves meaningful work it can carry out independently.
Like most dogs, positive motivational incentives such as treats, engaging games, or affection work best. The sensitive Kai reacts poorly to harshness, loud voices, or violence, often leading to fear-driven aggression.
Besides experience and consistency, a Kai owner should exhibit calmness, patience, and a loving, gentle hand.
Pay special attention to the Kai Ken’s hunting instinct. Keeping this dog with other pets necessitates training it from puppyhood to understand other animals aren’t prey but pack members. To avoid unpleasant surprises, it’s best to forgo other furry housemates like cats, hamsters, or rabbits—no amount of training and socialisation can truly suppress a Kai’s hunting instinct.
Once caught up in hunting fever, a Kai is unlikely to respond to its owner’s recall. A lead and a sturdy fence around the property are fundamental for any Kai owner.
Daily movement takes up a considerable amount of time. These Japanese hunting dogs need above-average exercise and activity levels corresponding to their breeding history.
A Kai Ken that doesn’t hunt and is only walked twice daily will not only be physically but also mentally unfulfilled.
Owners outside Japan with a Kai must allocate at least three hours or more for their dog’s exercise. Long hikes with the dog or bike rides, with the Kai running alongside, are ideal for physical activity.
Dog sports with the Kai? While the Kai’s physical fitness and muscular body make it suitable for various dog sports, its dominant nature and independence often hinder performing many exercises.
The Kai’s limited prevalence also adds to its charm, as it is considered very original and pure compared to other Japanese hunting dogs.
This is evident not only in its behaviour but also in its robust health. Breed-specific diseases, typically spread through uncontrolled breeding, are rare in the Kai.
The Kai experiences few health issues and has a high average life expectancy of 12 to 15 years.
In Japan, the Kai earns its food almost entirely through hunting, eating what the hunter shares from the captured animals. Those keeping the Kai as a family companion cannot maintain this primitive diet.
To feed the dog as naturally as possible, many owners opt for the BARF method (biologically appropriate raw feeding), offering raw meat with vegetables or rice. This diet suits the Kai well.
Anyone wanting to use this method must understand their dog’s nutrient needs and the nutritional content of different foods.
The Kai can be fed dry or wet food just as well. It’s essential to check the ingredients to keep the dog healthy. Excessive fillers can cause stomach issues and other problems, like allergies.
Chemical preservatives, artificial flavour enhancers, or sugar should not be in dog food. The food’s content and quantity should align with the dog’s size, weight, and activity level.
Tip: An adult Kai typically does well with one to two meals a day.
High veterinary bills or extensive, time-consuming care aren’t concerns for this robust and naturally very clean dog.
Regular brushing or combing of the fur is sufficient. During shedding season (twice a year), the Kai should be brushed daily to remove dead hairs and reduce fur clumps around the house.
The Kai Inu originates from the “Kai” province, a mountainous region in Japan’s Yamanashi Prefecture.
It descends from various medium-sized Japanese dogs used for hunting bears, deer, wild boars, badgers, and hares for millennia.
Asian hunters valued these dogs for their great independence and fearlessness, traits that made them unafraid to confront even fully grown bears.
The Kai’s remote, hard-to-reach homeland and pack formation tendencies likely contributed to the breed’s purity.
In 1934, due to their cultural significance, Japan declared the Kai a natural monument. Since then, its export from Japan, previously possible only under special conditions, has been strictly prohibited. Few breeders have Kai Ken operations in Europe.
Dreaming of seeing a true Kai outside Japan? It requires effort. Your best chance might be at an international dog show where this breed is occasionally featured. Spotting a Kai on the street is also very rare.
Practically no breeders for Kais exist in most regions, making it almost impossible to purchase one outside Japan. If that seems too complicated, consider related breeds like the Akita Inu or Shiba Inu, resembling the Kai in character and appearance.
The Kai is hard to come by outside Japan. Choosing this breed involves considerable effort, including thoroughly considering if the Kai suits your lifestyle.
Demanding and complex, the Kai is meant for professionals. However, those who rise to the challenge will be rewarded with an exceptionally loyal and typically healthy dog of rare distinction.
The Goldendoodle isn't a breed, but a pairing between Golden Retrievers and Medium or Standard Poodles. Marketed as a low-maintenance dog for allergy sufferers, this hybrid is enjoying increasing popularity amongst dog lovers, similar to the Labradoodle.
The Labradoodle is a pioneer amongst designer dogs. Whilst there are serious endeavours in Australia to establish this Poodle and Labrador Retriever hybrid as a stand-alone breed, most specimens found in Europe aren't bred according to a standard.
