Dachshunds have a form of dwarfism, chondrodystrophy, that gives them their short legs — and also causes the cushioning discs between their vertebrae to harden and degenerate early, often from the first year of life. A hardened disc can bulge or burst into the spinal canal, pressing on the cord. This is intervertebral disc disease, IVDD.

Studies put the lifetime incidence in dachshunds at roughly 20 to 25 percent, far higher than any other breed. It is the single most important health issue in the breed and the reason so much of dachshund care is about the back.

The warning signs

Early or mild signs: reluctance to jump or do stairs, a hunched back, shivering, yelping when picked up, a tucked belly, walking "on eggshells", loss of appetite. These mean stop all activity and call your vet the same day.

Serious signs: wobbly or crossing back legs, dragging a paw, knuckling over, and — the true emergency — sudden inability to walk or stand, or no feeling in the toes. Loss of the ability to walk is a "get to a surgical vet now" situation; the chance of recovery drops sharply after the first 24 to 48 hours, and fastest of all once deep pain sensation is gone.

Treatment

Mild cases are managed conservatively: strict crate rest for four to six weeks (not "take it easy" — genuine confinement), anti-inflammatory and pain medication, then a slow return to activity. Cutting corners on the rest is the commonest reason conservative treatment fails.

Moderate to severe cases, and dogs that lose the ability to walk, usually need MRI and decompressive surgery. Done promptly by a specialist, success rates are good — often 90 percent or better for dogs that still have pain sensation. Rehab, hydrotherapy and lifelong weight control follow.

Screening and prevention

Some countries run X-ray screening schemes that score the calcified discs visible in a young adult dachshund; dogs with fewer calcifications are lower risk and preferred for breeding. If you are buying a puppy, ask whether the parents have been screened.

For your own dog: keep it lean, ban jumping on and off furniture, use ramps, support the back and chest whenever you lift, use a harness not a neck collar, and keep it fit with regular low-impact walking. None of this guarantees safety, but together they meaningfully lower the odds.
