Chihuahuas typically live between 12 and 20 years, with the average lifespan generally falling around 14 to 16 years. They are considered one of the longest-living dog breeds. Many Chihuahuas live well into their late teens, and some have even been known to reach their early 20s, with the oldest recorded Chihuahua living to 23 years old
. The wide range in lifespan is influenced by factors such as genetics, overall health care, diet, exercise, and environmental conditions. Regular veterinary visits and proper care can help maximize a Chihuahua's longevity
. In summary:
- Average lifespan: 14–16 years
- Typical range: 12–20 years
- Exceptional cases: up to 23 years
This longevity is partly due to their small size, which generally correlates with longer life expectancy in dogs compared to larger breeds
