About Dogue de Bordeaux aging
The average Dogue de Bordeaux lives between 5 and 8 years, with 7 years being typical. Dogues de Bordeaux are wrinkle-faced French mastiffs — calm, loyal, physically powerful.
Breed-specific note: One of the shortest-lived breeds. Prioritize cancer screenings from age 3.
Life stages for Dogue de Bordeauxs
Based on a typical lifespan of 7 years, here's roughly when your Dogue de Bordeaux enters each life stage:
- Puppy: birth to 6 months — rapid physical and mental development.
- Junior: 6 to 12 months — adolescence, social maturation.
- Adult: 1 year to ~4 years — peak health and energy.
- Mature: ~4 to 5 years — early signs of aging may emerge.
- Senior: 5 to 7 years — slower pace, more rest, extra care.
- Golden years: 7+ years — every day is a gift.
How we calculate Dogue de Bordeaux age
Our calculator uses the UCSD epigenetic formula published by Wang et al. in 2020, which maps dog age to human age based on DNA methylation patterns. Breed-specific lifespan data comes from the American Kennel Club and peer-reviewed veterinary studies. For a Dogue de Bordeaux specifically, this gives you a more personalized result than generic calculators.
Dogue de Bordeaux age chart in human years
This table is calculated for the Dogue de Bordeaux's own 7-year average lifespan, so the life-stage column differs from a generic dog age chart. Human-year figures use the epigenetic formula; the AAHA column shows the size-adjusted method for comparison.
| Dogue de Bordeaux age | Human years (epigenetic) | Human years (AAHA) | Life stage |
|---|---|---|---|
| 1 year | 31 | 15 | Junior |
| 2 years | 42 | 24 | Adult |
| 3 years | 49 | 31 | Adult |
| 4 years | 53 | 38 | Mature |
| 5 years | 57 | 45 | Mature |
| 6 years | 60 | 52 | Senior |
| 7 years | 62 | 59 | Senior |
| 8 years | 64 | 66 | Golden years |

How the Dogue de Bordeaux compares
At an average of 7 years, the Dogue de Bordeaux sits 5.4 years below the 12.4-year average across all 180 breeds we track, and 2.4 years below the 9.4-year average for the 19 giant breeds in the dataset. It ranks joint #18 of 19 among giant breeds by average lifespan (tied with 1 other), and lives longer than roughly 0% of the breeds we list.
Dogue de Bordeaux age: frequently asked questions
How old is a 1-year-old Dogue de Bordeaux in human years?
A 1-year-old Dogue de Bordeaux is roughly 31 in human years. The UCSD epigenetic formula (16 × ln(age) + 31) puts the first year of a dog's life far ahead of a human's first year, which is why a one-year-old dog is already a young adult rather than a toddler.
How old is a 7-year-old Dogue de Bordeaux in human years?
A 7-year-old Dogue de Bordeaux is about 62 in human years by the epigenetic method. The older "multiply by seven" rule of thumb would say 49, and the size-adjusted AAHA method gives about 59 for a giant dog — the three methods disagree because dogs age fastest early in life, not at a constant rate.
What is the average lifespan of a Dogue de Bordeaux?
Dogue de Bordeauxs live about 7 years on average, with a typical range of 5 to 8 years. Giant breeds have the shortest average lifespans of any size class, so each life stage is reached at a younger calendar age.
When is a Dogue de Bordeaux considered a senior dog?
Using the last quarter of the average lifespan as the senior threshold, a Dogue de Bordeaux enters its senior years at roughly 5 years old — about 57 in human terms. Before that, the mature phase runs from around 4 to 5 years.
How much does a Dogue de Bordeaux weigh on average?
An adult Dogue de Bordeaux averages about 55 kg (121 lb), which places it in the giant size class. Size class matters for age conversion because the AAHA size-adjusted method applies a different yearly rate to each class.
At what age does a Dogue de Bordeaux reach the human equivalent of 60?
The epigenetic curve crosses human age 60 at about 6.1 dog years — the same for every breed, because the formula is based on DNA methylation rather than breed. What differs per breed is how much of its expected 7-year lifespan remains at that point.
Why do different Dogue de Bordeaux age calculators give different results?
Because they use different models. This page reports the UCSD epigenetic clock from Wang et al. (2020), which maps dog age to human age through DNA methylation patterns. The AAHA method instead adjusts by body size, and the "×7" rule is a folk approximation with no research basis. For a Dogue de Bordeaux at 10 years the epigenetic method gives about 68 human years.
Is there anything specific about how Dogue de Bordeauxs age?
One of the shortest-lived breeds. Prioritize cancer screenings from age 3. Dogues de Bordeaux are wrinkle-faced French mastiffs — calm, loyal, physically powerful.
How old is a 2-year-old Dogue de Bordeaux, and a 5-year-old?
A 2-year-old Dogue de Bordeaux is roughly 42 in human years and a 5-year-old is about 57. The gap between those two ages is smaller than the gap between birth and age one, because the aging curve is logarithmic — it rises steeply at first and then flattens. Across a full 7-year lifespan a Dogue de Bordeaux reaches roughly 62 human years.
