Presa Canario Size
As a large breed, a Presa Canario 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.
Presa Canario Lifespan
How long does a Presa Canario live?
The American Kennel Club publishes a life expectancy of 9–11 years for the Presa Canario, on its breed page. That is a figure for the breed, not a prediction for one dog — an individual Presa Canario can fall on either side of it.
A second source measured it instead of publishing it. McMillan et al. (2024) followed 144 dogs of this breed in the United Kingdom and recorded 98 deaths, giving a median age at death of 7.7 years (95% CI 7–9.5 years).
⚠️ The two do not agree, and the gap is not small: 9–11 years against 7.7 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.
Presa Canario Growth Chart
What a Presa Canario 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 44.0 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 Presa Canario weigh?
A Presa Canario weighs 84–110 lb (40–65 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 88–143 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 Presa Canario a large dog?
Yes — a Presa Canario counts as a large breed, going by the middle of its adult weight range (40–65 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 Presa Canario stop growing?
Later than a small dog. Hawthorne et al. (2004) measured that larger breeds keep gaining weight for longer, so a Presa Canario 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 84–110 lb down to a single number would look more precise while being less true.
How long does a Presa Canario live?
The American Kennel Club publishes a life expectancy of 9–11 years for the breed, re-checked here every week. That is a figure for the breed, not a prediction for one dog: an individual Presa Canario 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 144 dogs of this breed in the United Kingdom, recorded 98 deaths, and report a median age at death of 7.7 years (95% CI 7–9.5 years). The two disagree here — 9–11 years against 7.7 years — and we show both rather than averaging them, because they are not measuring the same thing.
