well the dog chihuahua can live up to 20 years(more or less) smaller dogs usually live longer than larger dogs
It depends on healthy you keep them. The average life expectancy of Chihuahuas is 15 to 18 years. Unless they get genital herpes, which can shave off approximately two to three years. Be careful.
Chihuahua's can live up to 15 (111 doggie years) years old and more!!

They can still die before that though so be careful and love your little doggie!
