The average lifespan of a dog is around 10-13 years, but some breeds have a much shorter life expectancy.
Breeds such as the Great Dane, Irish Wolfhound, and Bernese Mountain Dog have an average lifespan of only 6-8 years.
Factors that contribute to shorter lifespans in dogs include genetics, size, and health issues.
Smaller breeds tend to live longer than larger breeds, as they have fewer health problems and a slower rate of aging.
Breeds with genetic health issues, such as the Bulldog and Boxer, also have shorter lifespans.
Owners can help extend their dog's lifespan by providing proper nutrition, exercise, and regular veterinary care.
