Being one of the smallest dog breeds, Chihuahuas have made their place in the hearts of people worldwide due to their big personalities, unique characteristics, and surprisingly long lifespan. They have a rich history dating back to ancient Mexican civilizations, making them one of the oldest dog breeds in the Americas.
The average lifespan of a Chihuahua lies anywhere between 12 to 20 years, marking them as one of the longest-living breed among dogs. Factors influencing their lifespan include genetics, diet, healthcare, housing conditions, and their overall management of genetic disorders. One of the interesting factors here is the reported median age of death – 8.2 years – which invites a need for further investigation.
