Siberian Husky Size
As a medium breed, a Siberian Husky reaches its adult weight earlier than a large dog — smaller breeds finish growing sooner (Hawthorne et al., 2004).
Siberian Husky Lifespan
How long does a Siberian Husky live?
The American Kennel Club publishes a life expectancy of 12–14 years for the Siberian Husky, on its breed page. That is a figure for the breed, not a prediction for one dog — an individual Siberian Husky can fall on either side of it.
A second source measured it instead of publishing it. McMillan et al. (2024) followed 4,453 dogs of this breed in the United Kingdom and recorded 1,947 deaths, giving a median age at death of 11.9 years (95% CI 11.7–12 years).
⚠️ The two do not agree, and the gap is not small: 12–14 years against 11.9 years. We show both rather than averaging them, because they are not measuring the same thing. The AKC figure is what the breed club publishes for the breed; the McMillan figure is the age half of the dogs in that study had died by. A median at death sits below a life expectancy almost by construction — and here it lands below the published range, which is worth knowing either way.
Siberian Husky Growth Chart
What a Siberian Husky 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 21.5 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 Siberian Husky weigh?
A Siberian Husky weighs 35–60 lb (15.5–28 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 34–62 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 Siberian Husky a medium dog?
Yes — a Siberian Husky counts as a medium breed, going by the middle of its adult weight range (15.5–28 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 Siberian Husky stop growing?
Earlier than a large dog. Hawthorne et al. (2004) measured that smaller breeds finish growing sooner, so a Siberian Husky 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 35–60 lb down to a single number would look more precise while being less true.
How long does a Siberian Husky live?
The American Kennel Club publishes a life expectancy of 12–14 years for the breed, re-checked here every week. That is a figure for the breed, not a prediction for one dog: an individual Siberian Husky can fall on either side of it, and how a dog is fed, exercised and cared for moves the odds. A second source measured it rather than publishing it: McMillan et al. (2024) followed 4,453 dogs of this breed in the United Kingdom, recorded 1,947 deaths, and report a median age at death of 11.9 years (95% CI 11.7–12 years). The two disagree here — 12–14 years against 11.9 years — and we show both rather than averaging them, because they are not measuring the same thing.
