One Dogs are one of favorite companions. From Golden Retrievers to French Bulldogs, many breeds are instantly recognizable. But beyond the popular and well-known dogs, there exists a fascinating world of extremely rare dog breeds some so uncommon that most people will never see one in person.
So, what is the rarest dog breed, and what makes a dog breed rare in the first place? This in-depth guide explores the rarest dog breeds in the world, explains why they are so uncommon, and helps you understand whether owning a rare dog is the right choice for you.
What Does “Rarest Dog Breed” Mean?
It is worth knowing the meaning of the term rare when it comes to the world of dogs before calling a certain breed rare.
A dog breed is regarded as rare when:
- The number of registered dogs in the world is very minimal.
- The breed is with minimal breeders.
- It can be physically confined.
The major kennel clubs such as the American Kennel Club (AKC) do not accept it.
The Rarest Dog Breed in the World: The Norwegian Lundehund
Uncommonness does not imply excellence. Not all rare breeds are the healthier, smarter, and better pets, they are simply less common.
Why the Norwegian Lundehund Is Considered the Rarest
Norwegian Lundehund is generally regarded as the rarest type of dogs in the world. At some stage, the breed was reduced to less than 20 dogs across the world, and the breed was left hanging at the edge of extinction.
To this day, the overall population is very minimal as compared to mainstream breeds.
Origin and History of the Norwegian Lundehund
Norwegian Lundehund was developed in Norway more than 1000 years ago. It was specially domesticated to predate on puffins, a seabird that inhabits Norway on the rocky cliffs.
This specialized occupation demanded unusual physical characteristics and the Lundehund possessed them to the present day.
Unique Physical Characteristics
Norwegian Lundehund is not like any other breed of dogs:
- Each foot has six toes (polydactyl).
- Very loose joints so that the dog can bend backwards.
- Capability of sealing its ears with the help of a muscle.
- Lightweight and agile body.
These modifications enabled the dog to climb sharp cliffs and squeeze through small crevices.
Personality/Temperament
Although the Lundehund looks strange, it is:
- Alert and energetic
- Witty, yet self-reliant
- Loyal to its family
- Sometimes stubborn
The breed is well adapted to the knowledgeable dog owners who appreciate primitive dog behavior.
Health Considerations
The greatest difficulty with the Norwegian Lundehund is the Lundehund Syndrome, which is a digestive disorder due to low genetic diversity. This is a condition which needs to be managed throughout life and proper dieting.

Geographic Isolation
The breeds that are formed in distant regions tend to be localized.
Specialized Purpose
The domesticated dogs that are used to perform certain tasks might become obsolete.
Limited Genetic Pool
Small populations render breeding hard.
Lack of Popularity
The demand of the breed is very much influenced by media exposure.
