The Labrador Retriever is classified by The Royal Kennel Club as a large breed, with adults typically weighing 25–36 kg, and a median life expectancy of around 13.1 years, according to a 2024 analysis of UK veterinary records by Dogs Trust. Larger breeds tend to reach adulthood and old age faster than smaller ones, so a Labrador's ageing curve is noticeably steeper in the later years than, say, a Cocker Spaniel's.

What this means for your Labrador

Labradors are famously food-motivated, which makes weight management one of the biggest factors in how well they age — an overweight Labrador is at much higher risk of joint problems, particularly hip and elbow dysplasia, which the breed is already predisposed to. Keeping your Lab at a healthy weight throughout life is one of the most effective things you can do to support healthy ageing.

Ear infections are also common, thanks to those floppy ears trapping moisture, so regular checks are worth building into your routine, especially if your dog swims often.

When is a Labrador considered a senior?

Based on The Royal Kennel Club's size-adjusted guidance, large breeds like the Labrador are generally considered senior from around 5 dog years old — noticeably earlier than smaller breeds. This doesn't mean your dog suddenly "becomes old" at that point, but it's a sensible time to start twice-yearly vet check-ups if you haven't already, and to keep a closer eye on mobility and weight.
