Why does the dachshund have such short legs?

Over 15 years handling, testing, and restoring pocket, fixed-blade, and Damascus steel knives across hunting and everyday-carry disciplines.

The sound of little claws on the floor in the morning, that happy trot when they come looking for a cuddle… Have you ever wondered, looking at their unique physique: why does the dachshund have such short legs on such a long body? The answer lies in a single gene that tells the whole story of this small-statured dog.

Why does the dachshund have such short legs: one gene, centuries of history

The FGF4 gene: what stops limb growth

Behind those short legs lies a genetic trait: chondrodystrophy in dachshunds.

In 2009, researcher Heidi Parker’s team published a study in the journal Science. Scientists identified the culprit: a specific gene called FGF4. It acts as a signal that tells cartilage to stop growing sooner than expected.

This same mechanism also weakens the spinal discs. The dachshund’s short legs and the fragility of their back share the same genetic origin.

Why did breeders seek out this silhouette?

The origins of the dachshund date back to the Middle Ages. In Germany, short-legged hounds were gradually selected for underground hunting. Brave and persistent, they had to be able to squeeze into tunnels to flush out badgers or foxes.

These dogs evolved over the centuries to become the dachshund we know today. However, the breed was not officially structured until much later, with the drafting of its first standard in 1879.

Their short, sturdy legs allowed them to dig and crawl through narrow passages. Their broad, deep chest gave them the stamina and strength needed to face combative prey.

A profile adapted to every terrain

The FCI recognizes three official dachshund varieties (within Group 4, for underground and above-ground hunting dogs), each calibrated for a distinct terrain:

The Kaninchen (Rabbit Dachshund) generally weighs up to 3.5 kg. Historically, it was intended for pursuing wild rabbits in their narrow tunnels and burrows.

The Miniature dachshund generally weighs between 3.5 and 7 kg. It was notably used in small burrows and for ferret hunting.

Finally, the Standard dachshund generally weighs between 7 and 15 kg. Its morphology allowed it to explore the deep tunnels of badgers and foxes.

Note: the dapple coat defines a specific color pattern. This trait developed over the centuries through the dachshund’s origins and the work of breeders.

A profile increasingly low to the ground

In a century of selective breeding, the “sausage dog” has moved even closer to the ground. Shorter-legged than in the past, today’s Doxie puts more strain on their back.

What is the impact of the dachshund’s short legs on their health?

Pes varus: when their little paws curve

Observe your companion when they stand straight in front of you. Do you sometimes notice a slight deformation of the front leg? This phenomenon is called pes varus and comes directly from chondrodystrophy: the two bones of the forearm do not grow at the same rate. When one stops growing too early, the other continues to push, curving inward.

When should you seek veterinary advice?

A slight curvature is part of the breed’s classic morphology. However, if it becomes very pronounced, and if your beloved dog hesitates to put weight on their paw or shows a stiff gait, a veterinary consultation is necessary to prevent the onset of arthritis.

What this means for their joints

When they jump off the sofa or dash down the stairs at full speed, their little legs don’t have the height needed to cushion the landing. The shockwave travels directly up their back. It is this repetition of small impacts that eventually weakens their spine.

Dachshunds are 10 to 12 times more likely to develop a herniated disc than other breeds. To protect your companion’s spine and avoid back pain, a few simple daily habits make all the difference.

The 4 essential tips to protect your dachshund’s short legs and long back

Is your dachshund experiencing back pain due to their short legs? Protecting their health requires little, but consistency is key:

No more repeated jumping: install a ramp at the foot of the bed, the sofa, and even for getting into the car. It saves them from jarring landings and protects their spine.
Manage the stairs: steps put a huge strain on their limbs and back. Place a gate at the bottom of the stairs to stop them from racing up and down and avoid repeated shocks.
A harness adapted to their morphology: choose a well-fitted harness that clears their shoulders without pulling on their neck.
Watch their ideal weight: every extra kilo puts additional pressure on their joints and strains their spine. Viewed from above, their silhouette should show a slight inward curve just after the ribs. When touched, the ribs should be easily felt without being too prominent.

The answer to the question “why does the dachshund have such short legs” lies in their history, written into every centimeter of their DNA. Learning to protect them every day means giving them the freedom to live their life as an intrepid dog to the fullest, while keeping their spine safe.

FAQ – Why does the dachshund have such short legs

What is the genetic disease of the dachshund?

The main mutation of the breed is called chondrodystrophy (linked to the FGF4 gene). It stops the growth of the long bones of the limbs and predisposes the dachshund to fragile intervertebral discs.

What are the common health problems in the sausage dog?

Herniated disc (IVDD) is the leading cause of veterinary visits, followed by angular limb deformities (pes varus) and weight gain, which is very harmful to the back.

Do the dachshund’s short legs prevent them from going on long walks?

Not at all. The Doxie is an endurance dog. You just need to avoid overly steep terrain. For long hikes, having a suitable carrier bag allows you to spare their body.

How do I know if my short-legged dog is suffering from joint pain?

Hesitation before jumping, a hunched back, a stiff gait, or whimpering when you pick them up should alert you. Knowing how to carry your dachshund is essential, but if the pain persists, consult a veterinarian without delay.
