What genetic health risks do Dachshunds face — and what can owners do?

A practical guide to Dachshund genetic health: IVDD (~25% risk), PRA, Lafora in wirehaired dogs, pattern baldness, obesity, dental disease, and the genetics of chondrodysplasia.

Overview

Sources used in this guide include breed and veterinary authorities (AKC, AVMA, Merck Veterinary Manual), canine genetics research and veterinary specialty resources. Where possible I cite peer-reviewed findings and clinical guidance.

Intervertebral disc disease (IVDD): the biggest single risk

• What it is: IVDD is degeneration and displacement or extrusion of intervertebral discs in the spine. In chondrodystrophic breeds like the Dachshund, disc degeneration happens earlier and more severely than in most dogs.
• How common: Dachshunds are at very high risk — lifetime estimates are often cited around 20–25% (about 1 in 4) for clinically significant IVDD, making IVDD the most important genetic-health issue for the breed.
• Why it happens: Many Dachshunds inherit a chondrodystrophic body plan that shortens limbs and alters disc biology. Genetic variants that drive short-legged morphology are strongly associated with premature disc degeneration (see 'Genetics of dwarfism' below).

• Back pain, reluctance to jump or climb stairs
• Weakness in the hind limbs, wobbliness
• Sudden paralysis, especially of the hind legs
• Loss of deep pain sensation (an emergency)

• Prevention: keep dogs lean (see obesity below), avoid repetitive jumping/stairs, use ramps and harnesses rather than collars for lifting.
• Early action: any suspicious back pain or hind-limb weakness requires immediate veterinary attention — early surgery or medical management improves outcomes.
• Diagnostics and treatment: your vet will use neurologic exam, radiographs, CT or MRI. Treatment ranges from strict medical therapy (rest, anti-inflammatories) to decompressive surgery (hemilaminectomy) depending on severity.

Progressive retinal atrophy (PRA)

• What it is: PRA is a group of inherited retinal degenerations that cause progressive loss of vision and ultimately blindness. Onset and progression vary by form and by breed.
• Dachshund risk: PRA has been reported in Dachshunds and models of PRA affect vision in several coat/size varieties. DNA tests exist for some specific PRA mutations; however not all genetic causes are covered by currently available tests.

• Early eye exams: have a veterinary ophthalmologist screen puppies and adults (CERF/BAER-type or ophthalmic exam) annually or as recommended.
• Genetic testing: use available breed-specific DNA tests before breeding to reduce PRA risk in offspring. Organizations such as OFA and breed clubs maintain testing programs.
• Management: while there is no cure for PRA, many dogs adapt well to vision loss if the home environment and routines are kept stable.

Lafora disease (myoclonic epilepsy) in wirehaired Dachshunds

• What it is: Lafora disease is a progressive myoclonic epilepsy characterized by spontaneous muscle jerks (myoclonus), seizures, behavioral changes and progressive decline. It is a fatal, late-onset neurodegenerative condition in affected dogs.
• Breed distribution: Lafora disease has been reported repeatedly in Miniature Wirehaired Dachshunds (and some related lines). Onset is typically young adult to middle age.
• Genetics: a specific mutation in the canine NHLRC1 (EPM2B) gene has been identified in affected Dachshunds; reliable DNA testing is available.

• Test wirehaired Dachshunds for the Lafora (NHLRC1) mutation before breeding. Puppies from a carrier-by-carrier or carrier-by-affected mating are at risk of developing disease.
• If your dog is a carrier: avoid breeding two carriers together; work with a genetic-savvy breeder to reduce risk while maintaining diversity.
• Management: symptomatic treatment for seizures is possible, but the disease is progressive. Early diagnosis helps with planning and supportive care.

Pattern baldness and coat/skin-related genetic issues

• What owners see: pattern baldness (areas with reduced hair growth), color-associated follicular dysplasia and other coat abnormalities can occur in Dachshunds. Certain coat and color patterns (dapple, piebald, color dilution) can be linked to congenital or inherited skin/hair disorders in some lines.
• Not the same as seasonal or immune-mediated hair loss: pattern/follicular dysplasia tends to be non-inflammatory and linked to hair-follicle structure rather than infection or allergy.

• If you see unusual or progressive hair loss, seek a veterinary dermatology evaluation to rule out parasites, infections, endocrine disease and then consider genetic causes.
• Breeding advice: responsible breeders avoid mating combinations that produce higher risk for coat-associated disorders (e.g., certain dilute/dapple combinations may create health risks such as 'double dapple' ocular problems).

Obesity predisposition and its implications

• Dachshunds have a compact body and relatively low energy needs; combined with easy feedability, many Dachshunds are prone to gaining excess weight.
• Why it matters: extra weight increases mechanical load on the spine and intervertebral discs — directly increasing IVDD risk and worsening outcomes when disc disease develops.

• Maintain ideal body condition using portion control, measured feeding, and routine exercise tailored to the dog's spine (walks, controlled play, supervised swimming).
• Regularly weigh your dog and use body condition scoring with your vet — even modest excess weight increases IVDD risk.
• Avoid diets with excessive calories or free-feeding. Ask your vet for a target weight and a feeding plan.

Dental disease (periodontal disease)

• Small breeds like Dachshunds are predisposed to early periodontal disease because of relatively crowded teeth in a small jaw.
• Consequences: periodontal disease causes pain, tooth loss and can contribute to systemic inflammation affecting the heart, kidneys and liver.

• Daily toothbrushing with canine toothpaste is the gold standard.
• Regular professional dental exams and cleanings under anesthesia, frequency based on your dog’s dental health (often annually or every 1–2 years for predisposed dogs).
• Home care adjuncts: dental chews, water additives and special diets can help but should not replace brushing.

The genetics of dwarfism (chondrodysplasia) and how it links to disease

• What chondrodysplasia means: Dachshunds are a chondrodystrophic/chondrodysplastic breed — their short limbs result from genetic changes that alter cartilage growth and limb development.
• Key genetic finding: research has identified expressed fibroblast growth factor (FGF4) retrogenes associated with the short-limbed (chondrodysplastic) phenotype in multiple dog breeds. These retrogenes change growth signaling in cartilage, producing the classic short-legged appearance.
• Connection to IVDD: the same genetic background that produces short legs also affects the discs, leading to earlier degeneration and higher risk of IVDD in Dachshunds than in non-chondrodystrophic breeds.

• The short-legged phenotype is breed-defining and is not going to be “bred out” without changing what makes a Dachshund a Dachshund. Instead, manage the associated risks: maintain lean body weight, limit high-impact activities, and screen breeding stock where possible.
• Genetic testing is improving: some labs offer tests that identify FGF4 retrogene status, which can inform risk estimation for disc disease in breeding decisions.

Practical checklist for owners and breeders

For puppy buyers and owners:

• Get an ophthalmic screen and a baseline dental exam.
• Ask breeder for genetic test results: Lafora (if wirehaired), available PRA tests, and any screening done for IVDD predisposition or family history.
• Keep Dachshunds lean: weigh monthly, use measured meals, ask vet for caloric targets.
• Reduce spinal risk: avoid prolonged jumping, use harnesses and ramps, provide stairs for beds/cars if needed.
• Know IVDD emergency signs and have a veterinary hospital contact for neurology/surgery.

• Use available DNA tests (Lafora, PRA variants, other known mutations) and keep complete health records.
• Avoid carrier-by-carrier matings for conditions with known recessive inheritance.
• Participate in breed health schemes (OFA/CHIC-type programs) and keep detailed pedigrees and health outcomes to improve selection.

When to seek specialist care

• Sudden hind-limb weakness, paralysis, or loss of deep pain: emergency veterinary evaluation immediately.
• Recurrent seizures or progressive neurologic signs: consult a neurologist and consider genetic testing for Lafora.
• Progressive vision loss: veterinary ophthalmology referral and genetic testing.
• Severe dental disease: veterinary dentistry for scaling, extractions and a home-care plan.

Key Takeaways

• IVDD is the single most important genetic-health issue in Dachshunds (roughly 1 in 4 may develop clinically significant IVDD); prevention focuses on weight control, activity modification and early veterinary care.
• Progressive retinal atrophy and Lafora disease (in wirehaired Dachshunds) are inherited neurological/ocular conditions with available DNA tests — test before breeding.
• Dachshunds are genetically chondrodystrophic (short-limbed) due to FGF4 retrogene effects; this defines the breed but increases IVDD risk.
• Pattern baldness/coat disorders and dental disease are common breed-related problems; prompt veterinary assessment and routine preventive care help manage these.
• Responsible breeding (genetic testing, avoiding risky matings) plus informed ownership (weight management, environmental adjustments, regular exams) reduces disease burden and improves lifespan and quality of life.
