Dogue de Bordeaux Size
As a giant breed, a Dogue de Bordeaux 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.
Dogue de Bordeaux Lifespan
How long does a Dogue de Bordeaux live?
The American Kennel Club publishes a life expectancy of 5–8 years for the Dogue de Bordeaux, on its breed page. That is a figure for the breed, not a prediction for one dog — an individual Dogue de Bordeaux can fall on either side of it.
A second source measured it instead of publishing it. McMillan et al. (2024) followed 3,427 dogs of this breed in the United Kingdom and recorded 1,204 deaths, giving a median age at death of 11.1 years (95% CI 10.6–11.7 years).
⚠️ The two do not agree, and the gap is not small: 5–8 years against 11.1 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.
Dogue de Bordeaux Growth Chart
What a Dogue de Bordeaux 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 47.4 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 Dogue de Bordeaux weigh?
A Dogue de Bordeaux weighs 99–110 lb (45–50 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 Dogue de Bordeaux a giant dog?
Yes — a Dogue de Bordeaux counts as a giant breed, going by the middle of its adult weight range (45–50 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 Dogue de Bordeaux stop growing?
Later than a small dog. Hawthorne et al. (2004) measured that larger breeds keep gaining weight for longer, so a Dogue de Bordeaux 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 99–110 lb down to a single number would look more precise while being less true.
How long does a Dogue de Bordeaux live?
The American Kennel Club publishes a life expectancy of 5–8 years for the breed, re-checked here every week. That is a figure for the breed, not a prediction for one dog: an individual Dogue de Bordeaux 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 3,427 dogs of this breed in the United Kingdom, recorded 1,204 deaths, and report a median age at death of 11.1 years (95% CI 10.6–11.7 years). The two disagree here — 5–8 years against 11.1 years — and we show both rather than averaging them, because they are not measuring the same thing.
