Brittany Age Calculator
A French pointing breed developed in the Brittany region in the late 19th century from spaniel-and-setter crosses for upland-bird hunting. Compact, leggy, often tailless, with a dense flat or wavy coat in orange-and-white or liver-and-white. The smallest of the versatile pointing breeds. Brittanies typically weigh 30–40 lb (13.6–18.1 kg) at adulthood and live 12–14 years on average.

How long do Brittanies live?
Brittanies typically live 12–14 years, with a median lifespan around 13 years. Medium-sized breeds like the Brittany have above-average lifespans for the canine size spectrum. The strongest modifiable factor is body condition: dogs kept at BCS 4–5/9 (lean) routinely outlive their average by 1–2 years, while overweight dogs lose a comparable amount. Dental care from puppyhood + annual bloodwork from middle age are the next two highest-leverage longevity inputs.
Origins of the Brittany
Developed in the Brittany region of north-western France in the mid-to-late 19th century from crosses of older French spaniel stock with English Pointers and Setters that hunting English gentry brought to French estates. Brittany hunters wanted a versatile dog small enough to work dense Breton hedgerows but possessing the pointing instinct of the English setters. The first formal breed standard was drafted in 1907 in the village of Loudeac, organized by Arthur Enaud. The breed reached the United States in 1931 and AKC recognition followed in 1934 under the name Brittany Spaniel. AKC formally dropped Spaniel from the name in 1982 to reflect the actual pointing-and-retrieving working style. The Brittany remains the most commonly registered AKC pointing breed and dominates amateur upland-bird field-trial competition in the United States and France.
How a Brittany ages
A Brittany's aging has two phases: front-loaded years one and two (15 + 9 = 24 cumulative human-equivalents), then the steady 5-per-year pace. A 5-year-old Brittany is around 39 in human terms; a 10-year-old, 64.
Lifespan for a Brittany centers around 14 years — the breed has no major short-lifespan conformational pressure, so the practical limiting factors are the standard senior-adult ones: weight, dental disease, joint maintenance, and the cumulative effect of annual veterinary check-ins.

Brittany weight chart
Adult weight for the Brittany typically falls between 30–40 lb (14–18 kg) — placing this breed in the medium breed band per AKC size classification. Weight outside this range warrants a vet conversation about body condition rather than a target weight: BCS 4–5 (a slight visible waist, ribs easily palpable but not visible) is the goal regardless of where in the breed range your individual dog lands.
| Stage | Typical weight (Brittany) | What to watch |
|---|---|---|
| 8 weeks (puppy) | ~5–7 lb | Weight gain trajectory matters more than the absolute number — track weekly. |
| 6 months | ~22–29 lb | Most small breeds at ~75% of adult by 6 months; large breeds at ~55%. |
| 12 months | ~36–40 lb | Small breeds usually fully grown. Large and giant breeds add 10-20% over the next 6-12 months. |
| Adult (12-15 mo+) | 30–40 lb | Hold steady at BCS 4-5. Excess weight directly shortens lifespan (Purina 2002 lifetime study: lean-fed dogs live ~1.8 years longer). |
Stage weights are size-band approximations using growth-curve percentiles from AAHA + Royal Canin breed-data references. Individual dogs vary ±20% from these midpoints. For a more precise current-vs-target trajectory, see the puppy growth calculator or the ideal-weight calculator.
Common health concerns to watch for
- Hip dysplasia — moderate prevalence in the breed; OFA-screened parents matter
- Epilepsy — idiopathic seizures have documented breed-typical patterns; usually well-managed with medication
- Hypothyroidism — middle-age coat thinning, weight gain, and lethargy warrant a thyroid panel
- Spinal muscular atrophy — rare inherited neurological disease; DNA test exists for breeding stock
- Hip and elbow dysplasia in some lines
This is general guidance based on size and breed averages. Always discuss specific concerns with your veterinarian.
Brittany life-stage milestones
Generic puppy/adult/senior bands often miss the breed-specific timing windows for orthopedic development, neuter timing, and senior protocols. The stages below are calibrated for the Brittany:
- 8 weeks (puppy arrival): Begin socialisation and bird exposure early - the working drive declares fast. First orthopedic exam. Schedule first ophthalmology check (CERF). Verify SMA DNA test results from breeder if available.
- 6 months (adolescence): Drive intensifies. Begin formal bird training if hunting is planned. First OFA hip prelim screen. Coat begins coming in - regular grooming of feathering prevents mats and burr accumulation.
- 1 year (young adult): Skeletally mature at 30-40 lb. Full OFA hip and elbow screen at 24 months. Annual cardiac auscultation. Establish 60+ minutes of daily exercise - the breed under-stimulates badly in apartment life.
- 3 years (prime adult): Peak working years. Idiopathic epilepsy onset window - first seizures typically appear between 1-5 years. Hypothyroidism may begin declaring. Annual thyroid panel from this age.
- 8 years (mature/senior): Senior bloodwork annually with thyroid emphasis. Hip arthritis from athletic working life. Continue moderate field work - the breed remains capable into senior years. Cataracts may declare.
- 11 years (geriatric): Brittanys regularly reach 13-15 years on lean condition and continued moderate exercise. Cognitive sharpness usually preserved. Mobility support for working-line individuals with hip wear.

Brittany age FAQ
How long do Brittanies live?
Brittanies typically live 12–14 years, with a median lifespan around 13 years. Medium-sized breeds like the Brittany have above-average lifespans for the canine size spectrum. The strongest modifiable factor is body condition: dogs kept at BCS 4–5/9 (lean) routinely outlive their average by 1–2 years, while overweight dogs lose a comparable amount. Dental care from puppyhood + annual bloodwork from middle age are the next two highest-leverage longevity inputs.
How old is a 7-year-old Brittany in human years?
Using the AKC size-based method, a 7-year-old Brittany is approximately 49 human years old. Try the calculator above with your dog's actual age and months for a precise answer.
What is the typical lifespan of a Brittany?
Brittanies typically live 12–14 years. Lifespan for a Brittany centers around 14 years — the breed has no major short-lifespan conformational pressure, so the practical limiting factors are the standard senior-adult ones: weight, dental disease, joint maintenance, and the cumulative effect of annual veterinary check-ins.
When does a Brittany become a senior?
As a medium-sized breed, a Brittany is generally considered senior at around 8 years old. Senior status signals a shift toward semi-annual veterinary check-ups and closer monitoring for arthritis, dental disease, and weight changes.
Are Brittanies long-lived?
Brittanies have an average lifespan for their size. Diet, exercise, and dental care are the strongest modifiable factors for longevity.
Is the Brittany a spaniel or a pointer?
Despite the older "Brittany Spaniel" label, the working style is that of a pointer. AKC dropped "Spaniel" from the official name in 1982 to reflect what the dogs actually do in the field — Brittanys lock up on game birds and retrieve them rather than flushing in the classic spaniel pattern. They compete in the Sporting Group against pointers and setters in field trials. The feathered coat reads setter, but the pointing instinct, fast quartering pace, and bird-finding strategy align with pointing breeds. Smaller frame and more biddable temperament than the English Pointer make them a popular choice for amateur upland hunters.
