Norwegian Buhund Size
As a medium breed, a Norwegian Buhund reaches its adult weight earlier than a large dog — smaller breeds finish growing sooner (Hawthorne et al., 2004).
Norwegian Buhund Lifespan
How long do Norwegian Buhunds live?
The American Kennel Club publishes a life expectancy of 12–15 years for the Norwegian Buhund, on its breed page. That is a figure for the breed, not a prediction for one dog — an individual Norwegian Buhund can fall on either side of it.
Norwegian Buhund Growth Chart
What a Norwegian Buhund 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 15.0 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 Buhund weigh?
A Norwegian Buhund weighs 26–40 lb (12–18 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.
Is a Norwegian Buhund a medium dog?
Yes — a Norwegian Buhund counts as a medium breed, going by the middle of its adult weight range (12–18 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 Buhund stop growing?
Earlier than a large dog. Hawthorne et al. (2004) measured that smaller breeds finish growing sooner, so a Norwegian Buhund 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 26–40 lb down to a single number would look more precise while being less true.
How long do Norwegian Buhunds 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 Buhund can fall on either side of it, and how a dog is fed, exercised and cared for moves the odds.
