Our best guess, not hard science. These figures come from history and old breeding records, our viewpoint, not proven fact.
Just like owning a car or any other liability, upkeep and maintenance is required — and dog ownership is no different. Particular breeds need more attention from the vet, others have higher grooming costs, while others will eat you out of house and home. We have built this tool to help you understand what to expect from owning this breed.

The Lifespan Diagram
A visual guide to how this breed moves through life. The horizontal axis shows age from birth to old age; the vertical axis represents overall function, health and quality of life. The curve rises quickly through puppyhood, holds high during the prime adult years, then gradually declines into the senior stage. The exact shape varies by breed. This is a conceptual illustration, not a clinical or veterinary prediction for any individual dog.
The curve score is a conceptual illustration, not observed veterinary data. Published median lifespan informed the x-axis. The y-axis was generated by piecewise mathematical functions.
The smallest dog of all, traced to the Techichi companion dogs kept by the peoples of ancient Mexico. Tap a circle inside to keep digging.
Suitability
Scores reflect typical breed traits. Individual dogs vary with upbringing and environment.
Exercise needs
Chihuahuas are small but surprisingly feisty. Short daily walks plus indoor play keep them content.
Typical breed guidelines. Individual dogs vary by age, health and temperament.
Grooming
Short-coated Chihuahuas need only a weekly brush. Long-coated varieties need brushing two or three times a week but rarely need professional grooming.
Typical breed guidelines. Costs vary by location and coat condition.
Training
Typical breed traits. Individual dogs vary with socialisation and consistency of training.
Chihuahuas are generally hardy for their size but are prone to dental problems, luxating patella and heart disease. Their fragile build also makes them vulnerable to trauma.
This is a general guide based on published breed health surveys and veterinary literature. Not all dogs will develop these conditions. Always obtain health-tested parents from a responsible breeder and maintain regular vet check-ups.
