First, be aware that the average life span of dogs is increasing, just as the average human life span is. A dachshund that is well cared for usually now lives to be 14 or 15 years old; many live longer. Second, all dogs require regular medical care, including annual physical exams, inoculations, heartworm tests and preventive medication, and dental care. Third, illness and debility affect dogs of all ages.
A full grown standard dachshund averages  16-28 lbs., while the miniature normally weighs less than 11 pounds. According to most kennel club standards, the miniature differs from the full-size only by size and weight. Offspring from miniature parents must never weigh more than the miniature standard to be considered a miniature as well.
