Dachshund dogs, also known as "weiner dogs" or "sausage dogs," typically live between 12 and 16 years on average. Some have been known to live beyond 16 years, with rare cases reaching up to 20 years or more. The lifespan is similar across the various sizes (standard, miniature) and coat types (short, long, wire-haired) of the breed. Factors influencing their longevity include genetics, diet, exercise, preventive healthcare, and overall lifestyle. Common causes of death in Dachshunds include old age, cancer, heart disease, and back-related health issues. Proper care can help extend their life and maintain their quality of life.
