The most common cause of death in dachshunds is simply old age, accounting for about 22% of deaths in the breed. Cancer follows at roughly 17%, and heart disease comes in third at about 14%. A large UK health survey of purebred dogs found the median age of death for dachshunds was 12.67 years, with an overall life expectancy of 12 to 16 years.
But dachshunds also face breed-specific risks that don’t always show up neatly in mortality statistics, particularly back problems that can lead to paralysis and, in some cases, euthanasia. Here’s a closer look at what dachshund owners should realistically expect.
Back Disease (IVDD)
Intervertebral disc disease, or IVDD, is the health problem most closely associated with dachshunds. Their long spines and short legs make them uniquely vulnerable to disc degeneration, where the cushioning material between vertebrae hardens and eventually ruptures into the spinal cord. This can cause anything from mild back pain to complete hind-leg paralysis, sometimes within hours.
Dachshunds develop IVDD at dramatically higher rates than other breeds. The case fatality rate (meaning the percentage of affected dogs that ultimately die or are euthanized because of the condition) is around 24% for miniature dachshunds and 25% for standard dachshunds. That’s actually lower than breeds like Dobermans and German Shepherds, where the fatality rate exceeds 60%, largely because dachshunds tend to develop disc problems in the mid-back rather than the neck, and owners of the breed are often more prepared for it.
Still, IVDD is a significant quality-of-life issue even when it isn’t fatal. Many dachshunds that survive an episode need surgery, weeks of crate rest, or ongoing mobility support like wheelchairs. The first episode most commonly strikes between ages 3 and 7, much earlier than most owners expect. Keeping your dachshund at a healthy weight, using ramps instead of letting them jump on and off furniture, and supporting their back when you pick them up can reduce the strain on vulnerable discs.
Cancer
Cancer is the second leading cause of death in dachshunds, responsible for about 17% of deaths. This is actually slightly lower than the average across all dog breeds, where cancer typically accounts for 20 to 30% of deaths depending on the survey. Dachshunds don’t have a dramatically elevated risk for any single type of cancer, but like all dogs, they become more susceptible as they age.
The types most commonly seen in dachshunds include mast cell tumors (skin lumps that can range from benign to aggressive), mammary tumors in unspayed females, and lymphoma. Because dachshunds live relatively long lives, they simply have more years in which cancer can develop. Regular veterinary checkups become especially important after age 8 or 9, and any new lump or unexplained weight loss is worth getting checked promptly.
Heart Disease
Heart conditions account for roughly 14% of dachshund deaths. The most common form is myxomatous mitral valve disease, a progressive condition where the valve between two chambers of the heart gradually deteriorates and begins to leak. It typically develops after age 8 and is especially prevalent in small breeds, with dachshunds among those at higher risk.
In the early stages, the only sign is a heart murmur your vet detects during a routine exam. As the valve worsens over months or years, the heart has to work harder to pump blood, eventually leading to fluid buildup in the lungs. Symptoms at that stage include coughing (especially at night or after lying down), exercise intolerance, and rapid breathing. Many dogs live comfortably for years after diagnosis with medication that reduces fluid retention and eases the heart’s workload.
Cushing’s Disease
Dachshunds are one of several small breeds predisposed to Cushing’s syndrome, a condition where the adrenal glands produce too much cortisol. It’s most often caused by a tiny benign tumor on the pituitary gland at the base of the brain. The excess cortisol affects nearly every system in the body, causing increased thirst, frequent urination, a pot-bellied appearance, hair thinning, and muscle weakness.
Cushing’s doesn’t usually kill a dachshund directly, but it accelerates other problems. Chronically elevated cortisol weakens the immune system, promotes diabetes, raises blood pressure, and can contribute to kidney damage. With treatment, dogs with the pituitary form of Cushing’s typically survive an average of 2 to 2.5 years on medication. Surgical options can extend that to 2 to 5 years but are less commonly pursued. The condition is most often diagnosed in middle-aged to older dogs, so it frequently overlaps with other age-related health issues.
What “Old Age” Actually Means
The single largest category in mortality surveys is “old age,” which covers about 22% of dachshund deaths. This isn’t a medical diagnosis. It reflects dogs that declined gradually without a single identifiable disease being named as the cause. In practice, these deaths involve some combination of organ systems slowly wearing out: kidneys losing function, joints becoming painful enough to limit mobility, cognitive decline, and the eventual decision by owners and veterinarians that quality of life has dropped below a humane threshold.
The fact that old age is the leading category is actually a positive signal. It means more dachshunds die of general aging than of any single disease, which is the pattern you see in breeds with relatively good overall health. A dachshund that avoids serious back problems and cancer has a strong chance of reaching 14 or 15 years.
Factors That Affect Longevity
Weight is probably the single most controllable factor in a dachshund’s lifespan. Obesity increases the mechanical load on an already vulnerable spine, raises the risk of IVDD episodes, worsens heart disease, and contributes to joint problems. Dachshunds are enthusiastic eaters and easy to overfeed, especially when treats become part of training routines. You should be able to feel your dachshund’s ribs without pressing hard, and they should have a visible waist when viewed from above.
There’s no strong evidence that coat type (smooth, long-haired, or wire-haired) or size variety (standard vs. miniature) significantly changes overall life expectancy, though individual health risks can vary. Miniature dachshunds may face slightly different patterns of disc disease than standards, but both varieties share the same general health profile and the same 12 to 16 year lifespan range.
Genetics play a meaningful role, particularly for IVDD. Dogs from lines with fewer back problems are less likely to develop severe disc disease themselves. If you’re getting a dachshund from a breeder, asking about the spinal health history of the parents and grandparents is one of the most useful questions you can ask.
