The Norwegian Lundehund is the least popular—or, more precisely, the rarest breed—in the American Kennel Club’s 2025 U.S. registration ranking. The list compares 202 AKC-recognized breeds using AKC registration statistics, not a census of every dog or every registry in the country. The Lundehund ranked No. 3 in 2024 and No. 1 in 2025, while the English Foxhound moved out of the top spot it held in 2024.
That ranking identifies which breed had the lowest position in this particular annual registration comparison. It does not prove that the Norwegian Lundehund is the world’s rarest dog, give an exact number of dogs in America, or establish one breed-specific reason for its uncommonness. Here is what the data supports—and what it does not.

The least popular dog breed in America in 2025
In the AKC’s latest rare-breed list, published for 2025, the Norwegian Lundehund is No. 1 rarest among the 202 breeds included. The ranking is based on dogs registered with the American Kennel Club, so “least popular” is shorthand for the lowest position in that registration dataset. It is not a measurement of online interest, shelter numbers, ownership satisfaction, or the total number of Lundehunds living in the United States.
AKC’s own wording matters because registration rankings have a defined scope. They cover dogs recorded by that registry and the breeds in the comparison set. A dog registered elsewhere, an unregistered dog, or a dog belonging to a breed outside the AKC set will not be represented in the same way.
#1 Best Overall
For the current ranking, see the AKC’s 2025 rarest-breed list. The AKC also publishes a separate most-popular-breeds list; the two lists should not be treated as a complete census of American dogs.
What changed from 2024 to 2025?
The Norwegian Lundehund’s position changed substantially in one year. It was No. 3 rarest in the 2024 AKC ranking and No. 1 rarest in 2025. The English Foxhound held the No. 1 rarest position in 2024. Those are annual rank positions, not registration totals.
| AKC ranking year | No. 1 rarest breed | Norwegian Lundehund’s position | Number of breeds counted |
|---|---|---|---|
| 2024 | English Foxhound | No. 3 rarest | Not stated in the cited 2025 announcement |
| 2025 | Norwegian Lundehund | No. 1 rarest | 202 AKC-recognized breeds |
AKC notes that the set of recognized breeds can change. When a new breed is added to the comparison, every breed’s relative position can move even if its underlying registration activity changes little. That is why a year-to-year rank should be read as a snapshot of a defined list, not as proof that a breed’s national population suddenly rose or fell.
What “least popular” does—and does not—mean
It means the lowest rank in an AKC registration comparison
AKC popularity and rarity rankings use registration statistics. In practical terms, the 2025 result says the Norwegian Lundehund occupied the rarest position among the 202 breeds AKC counted. The evidence reviewed for this ranking does not provide an exact number of Norwegian Lundehunds registered in the United States, so no defensible population figure can be attached to the No. 1 position.
Rank #2
It does not mean “worst,” “least lovable,” or unsuitable
Popularity is not a quality score. A breed can be uncommon because relatively few people encounter it, because its traditional work is less common, or because its needs and lifestyle fit a smaller share of households. None of those possibilities establishes that the breed is unhealthy, difficult, unfriendly, or a poor choice for every owner.
It does not cover every dog in America
Registration data cannot include dogs that were never registered with AKC or that appear only in another registry. It also cannot, by itself, describe the number of mixed-breed dogs, dogs in shelters, or dogs whose owners do not participate in registration systems. “Rarest in the 2025 AKC registration ranking” is therefore the most accurate phrase.
Why is the Norwegian Lundehund uncommon?
No source cited for the 2025 ranking gives a single, breed-specific causal explanation for the Norwegian Lundehund’s position or supplies a U.S. registration count. The responsible answer is to separate what AKC says generally about uncommon breeds from what is actually demonstrated about this particular breed.

Some breeds are rare in the United States but not elsewhere
A breed’s American registration activity does not necessarily mirror its status in its country or region of origin. A dog can have a small U.S. presence while being more familiar or more numerous elsewhere. The 2025 U.S. ranking alone cannot tell you how common the Norwegian Lundehund is worldwide.
Historical work may no longer be widespread
Many dog breeds were developed for jobs that shaped their numbers and distribution. If that work becomes less common, fewer households may seek the breed for its original purpose. AKC lists this as a general reason that recognized breeds can be uncommon; the cited material does not prove that this is the specific cause of the Lundehund’s current U.S. rank.
A narrow household fit can limit demand
AKC also notes that not every breed fits every household. Size, activity expectations, training demands, grooming, housing constraints, and the owner’s experience can all affect how many people actively seek a breed. That general principle should not be converted into an unsupported claim about the Norwegian Lundehund’s temperament or care requirements, because those breed-specific details are not established by the sources used here.
Limited visibility can reinforce rarity
When few dogs of a breed are seen in neighborhoods, shelters, shows, or media, potential owners may know little about it and may choose a more familiar breed instead. This is a plausible mechanism for low demand in many rare breeds, but the available AKC material does not quantify its effect on the Norwegian Lundehund.

A low registration rank is a starting point for questions, not an answer to every ownership question. The cited ranking and explanatory article do not establish the breed’s health profile, exercise needs, grooming routine, trainability, behavior around children or animals, or typical lifespan. Those subjects require current, breed-specific guidance from qualified veterinary and breed organizations.
- It does not provide a census: no exact U.S. population or registration total is stated in the evidence used here.
- It does not prove a cause: the general reasons AKC lists for rarity are not a diagnosis of why this breed ranks No. 1 rarest.
- It does not predict an individual dog: a registration category cannot describe every dog’s personality, health, or behavior.
- It does not guarantee scarcity everywhere: U.S. rarity may differ from availability in another country.
- It does not make a breed automatically desirable: unusual status should never replace a careful fit assessment.
How to interpret the 2025 AKC result responsibly
Use the precise label
When accuracy matters, write or say “the Norwegian Lundehund was the rarest breed in the AKC’s 2025 U.S. registration ranking.” That wording identifies the organization, year, geography, metric, and comparison group. It avoids the broader—and unsupported—claim that it is the rarest dog breed on Earth or that it is the least-owned dog in every American dataset.
Compare ranks, not imaginary totals
The change from No. 3 rarest in 2024 to No. 1 rarest in 2025 is meaningful as a change in relative position. It does not reveal how many registrations were gained or lost because the source does not state breed-specific totals. Nor does it prove a sudden change in public interest.
Check the year before making a current claim
AKC releases annual rankings, and the comparison set can change. A statement about the “current” least popular breed should identify its ranking year and be checked against the newest list available. The 2025 result is the latest ranking supplied for this article; a later annual list could produce a different answer.
If you are considering this rare breed
Rarity should prompt more preparation, not a rush to acquire a puppy. Start by determining whether the breed’s documented characteristics—once verified through authoritative breed-specific sources—fit your household, schedule, budget, housing, and ability to obtain veterinary care. Do not assume that a low ranking makes a dog easier, harder, healthier, or more valuable.

A practical decision checklist
- Define your evidence standard. Separate AKC ranking information from independent information about health, behavior, exercise, grooming, and training.
- Confirm local access. Ask veterinarians whether they routinely see the breed and whether specialist care or breed-familiar referral options are available in your area.
- Plan for a small breeder network. A rare breed may require patience, travel, and careful verification rather than an immediate purchase from the first listing you find.
- Evaluate the breeder. Ask for transparent records, health-testing documentation relevant to the breed, a written contract, and an opportunity to meet the dam and see where puppies are raised.
- Budget for the full lifetime. Include routine veterinary care, emergencies, training, insurance if available, food, supplies, transport, and possible travel to a breeder or specialist.
- Walk away from pressure. Scarcity claims, demands for rushed deposits, refusal to show records, or requests to ship a puppy without adequate screening are warning signs.
For breeder discovery, AKC says its AKC Marketplace can connect puppy seekers with a responsible breeder. A listing service is not a substitute for your own verification: review records, ask detailed questions, and ensure the arrangement complies with applicable laws and transport requirements.
Why responsible breeding matters for an uncommon breed
AKC President and CEO Tom DiNardo described rare-breed attention as a way to educate the public and encourage responsible ownership, adding that choosing a responsible breeder can help these breeds continue across generations. The point is preservation with welfare, not producing dogs simply because they are unusual.
For a small-population breed, responsible decisions have consequences beyond one household. Breeders and buyers need to consider genetic diversity, health screening, temperament, puppy socialization, placement quality, and lifetime support. Those are principles of responsible ownership; the ranking itself does not prove that the Norwegian Lundehund has any particular inherited condition or that one breeding strategy is appropriate.
Why annual rare-breed lists can change
Annual rankings are relative. A breed can move because its own registration activity changes, because another breed’s activity changes, or because AKC adds or removes breeds from the recognized comparison set. The 2024-to-2025 shift illustrates why rank should not be presented as a permanent label.
Registration statistics also measure participation in one registry rather than the entire dog population. They are useful for comparing AKC-recognized breeds within the stated year, but they cannot answer questions about unregistered dogs, other registries, international prevalence, or the number of dogs currently needing homes.
The bottom line for the title question
The Norwegian Lundehund is the least popular—or most precisely, the rarest—breed in the 2025 AKC U.S. registration ranking, which counts 202 breeds. It rose from No. 3 rarest in 2024 to No. 1 in 2025, while the English Foxhound held the top rarest position in 2024. The available evidence does not state an exact registration count or prove one specific reason for the Lundehund’s uncommonness. AKC’s general explanations—regional differences, declining relevance of historical work, and a narrower household fit—are useful context, not breed-specific findings.
Use the ranking as a carefully defined statistic, then investigate current, breed-specific health and ownership information before making a decision.
