Chihuahua age in human years
Chihuahuas are small dogs, and size sets the clock. The first year counts for 15 human years and the second adds 9, which puts a two-year-old at 24. After that each year adds about 4.5. A five-year-old is around 38, and most enter their senior years around 10 or 11. Most live somewhere in the 10 to 16 range.
