Miniature Dachshund
Miniature Dachshunds have a cited life expectancy of 14 years (McMillan 2024 / VetCompass, n=7,342, 95% CI 13.7 to 14.2). The most carried tested variant is Chondrodystrophy and Intervertebral Disc Disease Risk, in 100% of 213 Miniature Dachshunds tested (Donner 2023), then Cone-Rod Dystrophy (35%) and Progressive Retinal Atrophy (11%). Only 8 dogs stand behind the atlas figures here, so little is known yet.
What genetic diseases do Miniature Dachshunds carry?
From a panel of 250 Mendelian-disease variants screened in 1,054,293 dogs (Donner et al. 2023), Miniature Dachshunds carry 14 of them at observable frequency. Carrier frequency is not clinical risk. Most recessive variants require two copies for disease expression; many dominant variants show incomplete penetrance. Read this as a population fingerprint of what's in the gene pool, not a per-dog prediction.
FGF4what this gene does
FGF4 influences leg length by affecting bone growth, leading to shorter legs in certain breeds.
For your dog: If your dog is from a breed known to carry this gene, it's worth discussing spinal health with your vet, but being a carrier doesn’t guarantee problems.
RPGRIP1what this gene does
RPGRIP1 is a gene involved in the function of photoreceptor cells in the eye, which help dogs see in different light conditions.
For your dog: If your dog belongs to a breed known to carry RPGRIP1 mutations, it’s worth discussing with your vet to understand the risks and monitor eye health.
SOD1what this gene does
SOD1 is a gene that helps protect cells from damage caused by harmful molecules called free radicals.
For your dog: If your dog is a carrier of SOD1 variants, it's worth discussing with your vet, but remember carrier status doesn't mean your dog will get the disease.
GDNFwhat this gene does
GDNF is a gene that helps support nerve cells, especially those involved in sensing pain and movement.
For your dog: If your dog is from a breed that can carry this gene change, it’s worth asking your vet about testing to understand any potential risks.
PDK4what this gene does
PDK4 helps regulate how cells use energy, especially in the heart muscle.
For your dog: If your dog is one of the breeds known to carry this gene, it’s worth discussing heart health with your vet, but being a carrier doesn’t mean your dog will develop disease.
RAB3GAP1what this gene does
RAB3GAP1 is a gene involved in nerve cell function, particularly in how cells communicate and maintain their structure.
For your dog: If your dog is one of the breeds known to carry this gene variant, it's worth discussing genetic testing with your vet to understand any potential risks.
F7what this gene does
The F7 gene helps produce a protein important for blood clotting, which stops bleeding when dogs get injured.
For your dog: If your dog is from a breed known to carry F7 variants, it's worth mentioning to your vet before any surgery or if you notice unusual bleeding.
ADAMTS17what this gene does
ADAMTS17 is a gene that influences body size and also plays a role in certain eye conditions. It affects the structure of tissues in the eye and elsewhere in the body.
For your dog: If your dog belongs to a breed known to carry ADAMTS17 variants, it’s worth discussing genetic testing and eye exams with your vet to stay ahead of potential issues.
Full ADAMTS17 gene page →PRCDwhat this gene does
PRCD is a gene involved in the health of a dog's retina, the part of the eye that detects light and helps with vision.
For your dog: If your dog belongs to a breed known to carry PRCD changes, it's worth discussing eye health and potential genetic testing with your vet.
What these results mean for a Miniature Dachshund
99.5% of Miniature Dachshunds in the Donner 2023 cohort carried it (n=213).
- Two extra copies of a growth gene, FGF4, shape dog legs and spines. The one on chromosome 12 is the one tied to disc disease; the one on chromosome 18 shortens legs.
OMIA 000157-9615
“Two FGF4 retrogenes (FGF4L1 on chromosome 18 and FGF4L2 on chromosome 12) have been identified to cause dwarfism across many dog breeds.” OMIA 000157-9615
“Brown et al. (2017) reported that an FGF4 retrogene insertion in chromosome CFA12” OMIA 000157-9615
- Carrying it raises risk. It does not say which dog will have a disc problem. In Dachshunds researchers found the test is not a valid risk indicator on its own.

What to do
Ask your veterinarian what a carrier result changes for your dog. What lowers risk in a carrier is not established in the sources this page draws on.
No test, or a mix
Without a test nobody can say whether a dog carries it. Leg length alone does not tell you: the disc-disease copy and the short-leg copy are different insertions.

For researchers Population genetics, disease models and every recorded condition Open the research detail for the Miniature Dachshund
In the atlas, the Miniature Dachshund clusters consistently as Miniature Dachshund (100% of the 8 dogs here). Genetic diversity is high (mean heterozygosity 0.3218), reflecting either a mixed-breed cluster or breeds with broad genetic backgrounds.
Mean heterozygosity is 0.322, notably high, indicates broad genetic background. High breed predictability score (1.83), individual dogs of this breed reliably cluster together genetically. Only 8 dogs of this breed in the atlas, every individual contributes outsized weight to the breed's computed profile.
What the atlas genotypes say about Miniature Dachshund
Computed from the 14,478 CanVAS dogs in the Atlas, on an imputed genotype backbone: 77,215 directly typed sites per dog, imputed to 9.67 million variants.
The confidence below counts dogs, not reads: it is the size of the sample, and it is separate from how the genotypes were measured.
Not enough dogs in the atlas yet (n=8) for a reliable diversity figure. It fills in as more are added.
What does genetic diversity mean?
How varied a breed's gene pool is — the share of gene spots where a typical dog of the breed carries two different versions rather than two identical ones.
How to read it: Higher = more diverse. Among well-sampled breeds it ranges roughly 0.22 (least diverse) to 0.33 (most diverse).
Diversity is a strength, not a verdict on any individual dog. Lower diversity means it's worth paying attention to recessive-risk testing — not that a dog is doomed.
Not enough dogs in the atlas yet (n=8) to resolve cluster structure. It fills in as more are added.
What does within-breed variation mean?
How much individual dogs within the breed differ from each other genetically.
How to read it: Higher = more internal variety among individuals of the breed.
Sensitive to how many dogs of the breed we've sampled.
What does typical lifespan mean?
The median age dogs of the breed tend to reach.
How to read it: Higher = longer-lived. Compare to longevity-for-size to see whether it's just a size effect.
Drawn from population lifespan records; individual dogs vary widely with care, genetics, and luck.
Miniature Dachshunds are a natural model for human cancer.
Some cancers appear in Miniature Dachshunds and in people driven by the same somatically-altered genes, cohort by cohort and cited on both sides. That makes this breed part of how we understand, and one day treat, the human disease. This is not a prediction about your dog, it is a window into the biology we share.
Miniature Dachshunds are a natural model for human disease
Because the same genes cause the same conditions across species, the inherited conditions documented in Miniature Dachshunds help researchers understand, and work toward treating, the human diseases they model. This is the dog advancing human medicine. The breed models the human disease; it does not have it, and this is not a prediction for your dog.

Where every number on this page came from.
This page draws on three primary data sources. Carrier frequencies for the Mendelian section come from Donner et al. 2023 (CC-BY-4.0). We grade these data at evidence Limited because the cohort is a direct-to-consumer ascertainment, which biases toward owners who chose to test their dogs. The panel also uses tag-SNP proxies for some variants rather than direct causal-variant assays. Limited is a study-design grade, not a quality grade: the Donner cohort is the largest open canine-genotype dataset in existence and we are grateful for it. We rate the confounding MEDIUM.
Population-genetic dimensions (heterozygosity, intra-breed PCA distance, nearest neighbors, trait-locus frequencies) come from CanVAS (Brundage 2026), harmonized through the Sniff Atlas. The exact release date and verification commit are pinned at the bottom of the page so a researcher can trace a number back to a specific snapshot. The disease-gene-variant graph comes from OMIA (Online Mendelian Inheritance in Animals; Nicholas, Tammen, and the Sydney Informatics Hub at the Sydney School of Veterinary Science, The University of Sydney; retrieved April 2026, DOI 10.25910/2AMR-PV70).
What this page does not yet have. Inheritance modes and per-disease penetrance evidence from Donner 2023 are in the structured data for every variant the panel covers. Mondo, OMIM, Ensembl, and HGNC cross-references live on the gene and disease pages this page links to, rather than being repeated here. What is still absent from this breed page is anything not in the cited panel, and each such gap carries its cause where it appears.
How to cite this page. The computed dimensions on this page are derived from the open Sniff Atlas v1.0.1 (Gehring 2026, doi:10.5281/zenodo.20566358, CC-BY 4.0). Full citation formats including BibTeX, RIS, and CITATION.cff at sniff.world/cite.
