The German Shepherd Dog is classified by The Royal Kennel Club as a large breed, with adults typically weighing 22–40 kg, and a median life expectancy of around 11.3 years, according to a 2024 analysis of UK veterinary records by Dogs Trust. As with other large breeds, German Shepherds mature quickly in their first couple of years, and their ageing pace picks up noticeably from middle age onward.

What this means for your German Shepherd

German Shepherds are prone to hip and elbow dysplasia, and in later life some develop degenerative myelopathy, a progressive spinal cord condition that affects mobility in the hind legs. Because the breed is naturally active and working-bred, owners sometimes don't notice early mobility changes until they've progressed — so it's worth watching for subtle signs like reluctance to jump or climb stairs as your dog ages.

Keeping your German Shepherd at a healthy weight and maintaining regular, appropriate exercise well into their senior years helps support joint health and can slow the impact of these breed-related conditions.

When is a German Shepherd considered a senior?

Under The Royal Kennel Club's size-adjusted guidance, large breeds like the German Shepherd are generally considered senior from around 5 dog years old — a good point to start more frequent vet check-ups and mobility monitoring.
