Wikidata publishes 13–15 lb for this breed. The two sources don’t measure the same thing — see why.

Norwegian Lundehund Size

As a small breed, a Norwegian Lundehund reaches its adult weight earlier than a large dog — smaller breeds finish growing sooner (Hawthorne et al., 2004).

Norwegian Lundehund Lifespan

How long do Norwegian Lundehunds live?

The American Kennel Club publishes a life expectancy of 12–15 years for the Norwegian Lundehund, on its breed page. That is a figure for the breed, not a prediction for one dog — an individual Norwegian Lundehund can fall on either side of it.

Norwegian Lundehund Growth Chart

What a Norwegian Lundehund puppy weighs week by week, from the growth curve FEDIAF publishes (Nutritional Guidelines 2025, Table VII-8a) for a dog whose expected adult weight is 6.8 kg. It is an average, not a target, and it is only valid from 8 weeks to one year — FEDIAF notes that growth patterns show a certain individual variability. Read a row as the middle of a spread.

Common questions

How much does a full-grown Norwegian Lundehund weigh?

A Norwegian Lundehund weighs 12–18 lb (6–7 kg) as an adult. That range is the weight the American Kennel Club publishes in the breed's official standard, re-checked here every week — it is a typical weight across many adult dogs, not a target for one dog. Wikidata publishes 13–15 lb for the same breed — a breed standard and a set of measurements don't answer the same question, so this page names both rather than picking one.

Is a Norwegian Lundehund a small dog?

Yes — a Norwegian Lundehund counts as a small breed, going by the middle of its adult weight range (6–7 kg). The cut-offs between small, medium, large and giant are a common veterinary convention rather than one official standard, so a breed near a boundary can be described either way elsewhere.

When does a Norwegian Lundehund stop growing?

Earlier than a large dog. Hawthorne et al. (2004) measured that smaller breeds finish growing sooner, so a Norwegian Lundehund reaches something close to its adult weight before a big breed would. We don't publish a month-by-month figure, because no source gives one breed by breed — and an invented number would be worse than none.

Why is there a range instead of one weight?

Because the source publishes a range. Within any breed, weight varies with sex, genetics, build and health, and a mixed-breed dog usually falls between its parents' breeds. Narrowing 12–18 lb down to a single number would look more precise while being less true.

How long do Norwegian Lundehunds live?

The American Kennel Club publishes a life expectancy of 12–15 years for the breed, re-checked here every week. That is a figure for the breed, not a prediction for one dog: an individual Norwegian Lundehund can fall on either side of it, and how a dog is fed, exercised and cared for moves the odds.

Weight varies within the Norwegian Lundehund by sex, genetics and health, and mixed-breed dogs fall between their parents. This is a typical range, not a guarantee.
