About the Briard's ageing

The Briard is a large breed with an average lifespan of 12 to 12 years. Like other large-sized dogs, the Briard ages most rapidly in its first two years — reaching the rough equivalent of a 25-year-old human by its second birthday — and then ages more steadily.

Briards typically reach senior status around 7 years old. From that point on, screening for joint, dental and weight-related conditions becomes especially valuable. Large-class breeds tend to be prone to hip, elbow and cardiac issues; many owners begin joint supplementation and twice-yearly vet visits at this stage.

If your Briard is approaching the high end of its expected lifespan (12+ years), you're already doing something right. Continue to monitor mobility, appetite, weight and behaviour — and adjust food, exercise and vet check-up frequency accordingly.
