A German Shepherd is a large breed — typically 50–90 lb (22–40 kg) as an adult, living about 9–13 years. That size decides how fast a German Shepherd ages: a 1-year-old is about 15 in human years, a 2-year-old about 24, and after that each year adds about 6 human years. So a 5-year-old German Shepherd is about 42, and a 10-year-old is about 72.
| German Shepherd age | Human years | Life stage |

German Shepherds reach senior age at around 8 years old — about 60 in human years. A senior German Shepherd is not sick by definition, but it does need a little more attention: regular vet check-ups, weight control, shorter but frequent walks, and a comfortable bed away from draughts.
Watch hips and elbows — German Shepherds are prone to hip dysplasia, so keep weight lean and avoid hard jumping and rough play on slippery floors. Daily training and exercise keep them calm and healthy, and ask your vet about joint checks and senior screening from about age 8.
