Pembroke Welsh Corgi Weight, Size & Lifespan
How big does a Pembroke Welsh Corgi get?
A full-grown Pembroke Welsh Corgi is a medium dog, weighing about 20–26 lb as an adult.
- Adult weight
- 20–26 lb
- Also in kilograms
- 9–12 kg
- Size class

- Life expectancy
- 12–13 years
The American Kennel Club’s breed standard says “up to 30 pounds (male), up to 28 pounds (female)” — not a range this page can chart.
Pembroke Welsh Corgi Size
As a medium breed, a Pembroke Welsh Corgi reaches its adult weight earlier than a large dog — smaller breeds finish growing sooner (Hawthorne et al., 2004).
Pembroke Welsh Corgi Lifespan
How long does a Pembroke Welsh Corgi live?
The American Kennel Club publishes a life expectancy of 12–13 years for the Pembroke Welsh Corgi, on its breed page. That is a figure for the breed, not a prediction for one dog — an individual Pembroke Welsh Corgi can fall on either side of it.
A second source measured it instead of publishing it. McMillan et al. (2024) followed 643 dogs of this breed in the United Kingdom and recorded 221 deaths, giving a median age at death of 13.2 years (95% CI 12.7–13.6 years).
⚠️ The two do not agree, and the gap is not small: 12–13 years against 13.2 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 above the published range, which is worth knowing either way.
Pembroke Welsh Corgi Growth Chart
What a Pembroke Welsh Corgi 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 10.5 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 Pembroke Welsh Corgi weigh?
A Pembroke Welsh Corgi weighs 20–26 lb (9–12 kg) as an adult. That range is the mass Wikidata publishes for the breed under a CC0 license, re-checked here every week — it is a typical weight across many adult dogs, not a target for one dog.
Is a Pembroke Welsh Corgi a medium dog?
Yes — a Pembroke Welsh Corgi counts as a medium breed, going by the middle of its adult weight range (9–12 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 Pembroke Welsh Corgi stop growing?
Earlier than a large dog. Hawthorne et al. (2004) measured that smaller breeds finish growing sooner, so a Pembroke Welsh Corgi 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 20–26 lb down to a single number would look more precise while being less true.
How long does a Pembroke Welsh Corgi live?
The American Kennel Club publishes a life expectancy of 12–13 years for the breed, re-checked here every week. That is a figure for the breed, not a prediction for one dog: an individual Pembroke Welsh Corgi 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 643 dogs of this breed in the United Kingdom, recorded 221 deaths, and report a median age at death of 13.2 years (95% CI 12.7–13.6 years). The two disagree here — 12–13 years against 13.2 years — and we show both rather than averaging them, because they are not measuring the same thing.
