About Chihuahua Ownership in Illinois
Chihuahuas are the world's smallest dog breed and one of the most affordable to own. Their tiny size means minimal food costs, low medication dosages, and a very long lifespan that delivers excellent value per year of companionship.
Frequently Asked Questions
Are Chihuahuas the cheapest dog to own?
Chihuahuas are consistently among the cheapest breeds to own on a monthly basis. Their tiny food requirements ($15-$30/month), minimal medication doses, and low grooming costs make them very affordable. Their long lifespan (12-20 years) does mean total lifetime costs add up, but the per-year cost is among the lowest of any breed.
What health problems do Chihuahuas have?
Chihuahuas are prone to patellar luxation (knee slipping - surgery $1,500-$3,000 per knee if needed), tracheal collapse (a respiratory condition), dental disease (annual cleanings important), hypoglycemia in puppies, and heart disease in senior dogs. Genetic health testing reduces risk significantly.
How much does dental care cost for a Chihuahua?
Dental disease is the most common health issue in Chihuahuas. Annual professional dental cleanings cost $300-$700. Without regular dental care, extractions ($800-$2,000) are frequently needed in middle-aged Chihuahuas. Daily tooth brushing is one of the best investments in Chihuahua health.
How long do Chihuahuas live?
Chihuahuas are one of the longest-lived dog breeds, with many individuals living 15-20 years and some exceeding 20. This exceptional longevity, combined with low monthly costs, makes Chihuahuas one of the best lifetime value breeds - even though the relationship and associated costs extend over many years.
