Why guide dogs have a short life span

Guide dogs have a shorter life span because they work long hours, are under more stress than normal dogs, and have a very high level of energy and physical exertion, which has an impact on their life span, so the average life span of a guide dog may be a few years shorter than a normal dog. Not all guide dogs have a shorter life expectancy, but many have a limited number of years of service and can retire to enjoy a happy old age in their adopters’ homes when the time comes. Guide dogs can also live up to the age of a normal dog with the careful care of their owners.
