Spitz breeds, also known as Northern breeds, were originally bred in cold and snowy regions. The Japanese Spitz dogs came about in the 1920s after crossbreeding a number of other different spitz dogs from other locations, such as Australia, Canada, China, Siberia, and the United States. It all began with white German Spitz dogs.

This breed was officially recognized as the Japanese Spitz in 1948 with its distinct size, color, and fur features. Today, the Japanese Spitz breed is recognized by major kennel clubs like the Japanese Kennel Club and United Kennel Club, except the American Kennel Club because it is similar to the white Pomeranian, American Eskimo Dog, and Samoyed. Japan Kennel Club recognized this breed after World War II when the breed standards were finalized.

How to differentiate Japanese Spitz dogs And Others

While the Japanese Spitz, White Pomeranian, American Eskimo Dog, and Samoyed may look similar due to their fluffy white coats, some key differences exist between these breeds.

The Japanese Spitz is a small to medium-sized breed that typically weighs 11-20 pounds and stands 12-15 inches tall at the shoulder. They are known for their outgoing personality and are often described as playful, intelligent, and loyal.

The White Pomeranian, on the other hand, is a small toy breed that is descended from the larger Spitz-type dogs of the Arctic. They are known for their feisty and affectionate personality and are often described as lively, intelligent, and independent. They typically weigh between 3-7 pounds and stand 6-7 inches tall at the shoulder.

The American Eskimo Dog is a medium-sized breed that typically weighs between 20-35 pounds and stands 15-20 inches tall at the shoulder. This breed was originally developed in Germany and is known for its playful and affectionate personality.

The Samoyed is a large breed that was originally developed in Siberia for herding and pulling sleds. They typically weigh between 50-60 pounds and stand 19-23 inches tall at the shoulder. They are known for their gentle, intelligent, and independent personalities.


The Japanese Spitz is referred to as "small" in size in comparison to other dog breeds, but it is not as small as "toy" or "micro" bred dogs. At an adult weight of 10-25 pounds, these dogs usually grow to about 12-15" in height. Unlike other animals, the male and female Japanese Spitz typically grow to about the same size and are usually indistinguishable by size alone.


This playful dog is extremely energetic. Some of the most commonly used adjectives used to describe this breed include affectionate, friendly, playful, intelligent, and loyal. While they are very playful and energetic, Japanese Spitz prefers to be the center of attention for petting, snuggling, or just hanging out beside you. Japanese Spitz make a great family companion with their approachable personality and are rarely timid or aggressive. 

Japanese Spitz breeds are very social dogs, and most of the breeds get along well with other dogs, pets, and children.

This playful and loving pup does great with families, especially those with young kids. Because they are so affectionate and loyal, they become attached to their owners and families and love to play with kids and people of all ages. Japanese Spitz is a great size and has a super friendly personality, a perfect kid-friendly match for a full house.

Because they are so loyal, these dogs often can suffer from separation anxiety, and this causes them to react negatively when left alone for long amounts of time. They also are susceptible to barking at strangers or perceived threats to them or their families.

Diet/ Nutritional needs 

The Japanese Spitz is a small breed but is extremely active. So what is the best diet and nutrition to meet their needs? Portioning meals is important to make sure that their blood sugar and energy levels stay consistent throughout the day. If you have a puppy, feeding three small meals a day is recommended, about 8 hours apart. Once the puppy ages to around 6-12 months, it is appropriate to decrease the portioned meals to twice daily while still feeding the same amount overall. Depending on their size, these dogs should eat about ¾ cup to 1 ½ cups of well-balanced, nutritional dog food daily. Consult your veterinarian for additional specific food recommendations.

Activity/ Exercise needs

Even though this is a rather small-sized dog, because of its energetic personality, they need plenty of exercise and stimulation. They need plenty of room to run or to go on long walks throughout the day to get their energy out. This dog's recommended activity is at least 30 to 60 minutes of moderate exercise per day. Ideally, these dogs will have a large space to run freely outside, such as a backyard or enclosed park. Additional activities for these dogs can include mental stimulation, such as puzzles and toys that allow them to use up more energy when inside the home. 

Appearance/ Colors

The Japanese Spitz is often confused with other breeds, such as the Samoyed and American Eskimo, because of its long-haired, double-coat of bright white fur. Other distinctive features, besides its size, include a curled tail, a pointed snout, dark eyes, triangular pointed ears, and an athletic body.

Grooming needs

These non-hypoallergenic dogs have excessive fur due to their thick double coat. They shed a small amount throughout the year but will have larger sheds twice a year, losing most of the undercoat for a couple of weeks. Regular brushing is recommended, at least once weekly on a normal basis, plus more if needed during the time of their shed. Additional grooming needs include bathing as needed, as well as regular nail trims and teeth brushing for appropriate overall hygiene. 


Because this dog is moderately active, it should have a large space to run around, such as an enclosed backyard, and plenty of room to play inside.

Though they have lots of energy, because they are small, the Japanese Spitz also can adapt easily to apartment living if necessary. These dogs can do well in smaller living quarters as long as they get plenty of physical and mental stimulation and have room to run and play inside and outside.

Additionally, because they tend to bark, it is important to consider whether or not apartment living is ideal for you and your neighbors.

As energetic as these dogs are, they are not easily distracted and very trainable. Because of their loyalty and love for their owners, in addition to their intelligence level, they are extremely eager to please and make an active effort to learn what you are trying to teach them.

It is important, however, to find what motivates your dog, whether it's a treat or their favorite toy, to help facilitate the training process. The earlier you train your dog, the better, as it makes the process easier and will increase their confidence and loyalty to you.

If you have Japanese Spitz puppies, starting them on early socialization and enrolling them in training school is important. Adult Japanese Spitz should also start training or enroll in training school if needed.

Life expectancy 

The Japanese Spitz has a predicted lifespan similar to other small canine breeds. Typically expected to live about 12 to 14 years, these dogs can live a long and happy life with you and your family.

Potential Health Issues

Japanese Spitz is generally a healthy breed with few genetic problems. With appropriate hygiene, diet, exercise, and love, your Japanese Spitz will live not only happily, but also healthily.

As with any dog, Japanese Spitz owners should bring their dog to their regular veterinarian for annual exams to ensure their health and prevent potential illnesses. Like all dog breeds, Japanese Spitz is prone to health issues, specifically patellar luxation, arthritis, and cancer.

Patellar Luxation

Patellar luxation is a common problem in small dog breeds, and it is a disorder where the kneecaps come dislocated, causing limping, lameness, stiffness, and pain in the hind legs. Depending on the severity of this disorder, it may be able to be treated with surgery by your regular veterinarian.


Arthritis is actually common in many dogs. Like humans, their joints may become inflamed as the dog ages, causing stiffness, discomfort, and/or pain. Though there is no way to treat the damaged cartilage in the joints, your veterinarian may be able to recommend an NSAID, pain medication, or supplement to help ease discomfort.


Unfortunately, dogs are susceptible to cancer, and some breed more than others. With regular visits to the veterinarian, it is possible to catch cancer before it causes too much damage to the body. There are also veterinary Oncologists throughout the country who provide specialty care as needed.
