What Dog Breed Lives the Longest? The dog breed that often lives the longest is the Chihuahua, with a lifespan that can reach up to 18 to 20 years or more.
Other long-living dog breeds include the Dachshund, Toy Poodle, and Jack Russell Terrier, all known for their longevity.
Smaller breeds generally outlive larger ones due to their slower aging process and lower risk of developing age-related health issues.
How Long Do Dogs Live?
Smaller dog breeds tend to have longer lifespans, often living into their late teens or early 20s, while larger breeds like Great Danes and Newfoundlands typically only live around 7-10 years.
A notable exception is Bobi, a Portuguese Rafeiro do Alentejo who holds the record as the oldest dog at 30 years old.
The reason for this disparity is not fully understood, but one theory suggests that medical issues in larger breeds are more challenging to manage, leading to earlier euthanasia.
Factors Affecting Canine Lifespan
Several factors influence a dog’s lifespan, including breed, size, genetics, and overall health care. While genetics play a significant role, a dog’s environment and lifestyle can greatly impact their longevity.
Breed and Size
Smaller dogs like the Chihuahua, Dachshund, and Toy Poodle tend to live longer than larger breeds like Great Danes or Saint Bernards. This is because smaller dogs age slower and are less prone to certain health problems that affect larger dogs, such as joint issues and heart disease.
- Chihuahua: Average lifespan of 15 to 20 years.
- Dachshund: Known to live between 12 to 16 years.
- Toy Poodle: Typically lives around 14 to 18 years.

Diet and Nutrition
Proper nutrition can add years to a dog’s life. A balanced diet that meets all nutritional needs supports healthy organs, muscles, and bones, helping to prevent obesity—a leading cause of health problems in dogs.
- Balanced Diet: Dogs with well-balanced, nutrient-rich diets tend to have fewer health problems and live longer.
