Wikidata publishes 56–65 lb for this breed. The two sources don’t measure the same thing — see why.
Gordon Setter Size
As a large breed, a Gordon Setter keeps growing for longer than a small dog — larger breeds reach their adult weight months later (Hawthorne et al., 2004). Expect steady growth well past the first year.
Gordon Setter Lifespan
How long do Gordon Setters live?
The American Kennel Club publishes a life expectancy of 12–13 years for the Gordon Setter, on its breed page. That is a figure for the breed, not a prediction for one dog — an individual Gordon Setter can fall on either side of it.
A second source measured it instead of publishing it. McMillan et al. (2024) followed 393 dogs of this breed in the United Kingdom and recorded 138 deaths, giving a median age at death of 12.4 years (95% CI 12.1–12.8 years).
The two roughly agree here, which is not always the case: on 34 of the breeds on this site the measured median falls outside the range the AKC publishes, in both directions. They are still not the same measurement — a life expectancy for the breed on one side, the age half the studied dogs had died by on the other.
Gordon Setter Growth Chart
What a Gordon Setter 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 28.3 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 Gordon Setter weigh?
A Gordon Setter weighs 45–80 lb (25.5–29.5 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 56–65 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 Gordon Setter a large dog?
Yes — a Gordon Setter counts as a large breed, going by the middle of its adult weight range (25.5–29.5 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 Gordon Setter stop growing?
Later than a small dog. Hawthorne et al. (2004) measured that larger breeds keep gaining weight for longer, so a Gordon Setter is likely to fill out well past its first birthday. 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 45–80 lb down to a single number would look more precise while being less true.
How long do Gordon Setters 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 Gordon Setter 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 393 dogs of this breed in the United Kingdom, recorded 138 deaths, and report a median age at death of 12.4 years (95% CI 12.1–12.8 years).
