The big picture
Two of the most serious corgi conditions involve the spine, a direct consequence of the breed's long-back, short-leg build. The good news: the single biggest risk factor you control — body weight — sits under nearly all of them. Keep your corgi lean, protect its back, and buy from a health-testing breeder, and you've stacked the odds heavily in your favor.
The conditions at a glance
Intervertebral Disc Disease (IVDD)
The cushioning discs between vertebrae bulge or rupture and press on the spinal cord, causing pain, weakness, or paralysis. Corgis are predisposed because dwarf breeds' discs degenerate and calcify earlier.
Your levers: keep the dog lean, limit jumping and hard landings, and act fast on sudden back pain or weakness.
Degenerative Myelopathy (DM)
A progressive, ultimately fatal degeneration of the spinal cord causing painless hind-limb weakness that advances to paralysis, usually starting after age 8. No cure; supportive care and carts manage quality of life.
Your levers: a DNA test exists — but read the important nuance below before you panic over a result.
Hip Dysplasia
An inherited malformation of the hip joint that leads to arthritis and pain. Screened in breeding dogs via OFA or PennHIP evaluation.
Your levers: weight control and appropriate exercise reduce the symptomatic impact.
Von Willebrand Disease (Type I)
An inherited bleeding disorder — low von Willebrand clotting factor. Type I is the milder form, but it matters for surgery and injury. A DNA test is available.
Your levers: know your dog's status before any surgery; buy from a breeder who tests.
Eye Conditions
Inherited eye disorders, including progressive retinal atrophy (PRA). Breeding dogs should be certified clear by a veterinary ophthalmologist (OFA/CAER exam).
Your levers: choose tested parents; report vision changes to your vet.
Obesity
Not a disease of bad luck but of the food bowl — and the amplifier for nearly every other problem here (IVDD, arthritis, hip dysplasia, diabetes, heart disease).
Your levers: this one is almost entirely in your hands. See Keeping Your Corgi Lean.
IVDD — the conformation risk you can shape
Intervertebral disc disease is the condition most tied to a corgi's shape, and also the one where daily habits matter most. Because chondrodysplastic (dwarf) breeds have discs that degenerate and calcify earlier, a bad jump or twist can herniate a disc and compress the spinal cord.
Prevention is mostly lifestyle: keep the dog lean, limit jumping and hard landings (ramps for the car and couch, an "off" cue, no furniture-diving), and manage stairs. Act fast on symptoms — sudden back pain, a hunched posture, reluctance to move, wobbliness, or hind-limb weakness are emergencies. Early medical or surgical intervention dramatically affects the outcome, so call your vet immediately rather than waiting to "see if it improves."
Degenerative myelopathy — and the number every owner should know
DM is a heartbreaking disease: a slow, painless loss of hind-limb function that usually begins after age 8 and, over 1–3 years, progresses to the point that mobility fails. There's no cure, though physical therapy, supportive care, and rear-support carts can preserve quality of life for a long time.
DM is associated with a recessive mutation in the SOD1 gene (the c.118G>A variant, identified at the University of Missouri), and a DNA test is available. Pembrokes are one of the most-affected breeds and carry the mutation at high frequency — roughly 20–30% carry at least one copy.
It's easy to panic at an "at-risk" DNA result, but the genetics are not deterministic. On average, only about 1.1% of Pembrokes that test homozygous "at-risk" actually go on to develop clinical DM. The mutation appears necessary but is far from sufficient — other, still-unidentified factors gate whether the disease ever develops. The test is genuinely useful for breeding decisions and awareness, but it is not a reason to despair over a two-copy dog.
Hips, bleeding, and eyes — the breeder-screened conditions
Three more inherited conditions are the reason responsible breeders health-test their dogs:
- Hip dysplasia — screened via OFA or PennHIP hip evaluation. Careful breeders also screen elbows.
- Von Willebrand disease (Type I) — a bleeding disorder with a straightforward DNA test; knowing status matters most around surgery.
- Inherited eye disease — breeding dogs get an annual eye certification (OFA/CAER) from a veterinary ophthalmologist.
Other conditions noted in the breed include epilepsy, some cardiac and autoimmune issues, and a diabetes-research interest — which is exactly why the breed club runs an ongoing health survey to track true prevalence.
The breeder health-testing cheat sheet
When you're choosing a puppy, ask to see documentation of these on both parents. A breeder who tests, keeps puppies to ~10 weeks, and offers lifetime support is the best predictor of a healthy dog.
| Test | Method | What it screens |
|---|---|---|
| Hips | OFA or PennHIP | Hip dysplasia |
| Eyes | OFA/CAER exam by a veterinary ophthalmologist | Inherited eye disease (PRA and others) |
| Von Willebrand (vWD) | DNA test | Type I bleeding disorder |
| Degenerative myelopathy | SOD1 DNA test | DM (interpret with the ~1.1% nuance above) |
| Elbows, cardiac (optional) | OFA | Elbow dysplasia, heart |
FAQ
Sudden reluctance to move or jump, a hunched or tense back, yelping when picked up or touched, wobbly or weak hind legs, or dragging the back feet. Any of these warrants an immediate vet visit — early treatment strongly affects recovery.
Almost certainly not, statistically. Only about 1.1% of homozygous "at-risk" Pembrokes actually develop clinical DM. The result is meaningful for breeding decisions and for awareness after age 8, but it is not a diagnosis or a sentence.
Commonly 12–15 years (the AKC lists around 12–13), and sometimes longer with good weight and joint management. Keeping a corgi lean is one of the most effective things you can do to protect both lifespan and mobility.
Keep it lean and protect its back. Weight sits underneath IVDD, arthritis, hip problems, diabetes, and heart disease, so weight control is the highest-leverage habit you have. Start with Keeping Your Corgi Lean.
