Intervertebral Disc Disease in Pigs: Back Pain, Weakness, and Difficulty Walking

Quick Answer
  • Intervertebral disc disease (IVDD) means a spinal disc is bulging, degenerating, or herniating and may press on the spinal cord or nearby nerves.
  • Pigs with IVDD may show back pain, a hunched posture, reluctance to move, wobbliness, dragging of the rear legs, or sudden inability to stand.
  • See your vet promptly if your pig is weak, painful, or walking abnormally. See your vet immediately if your pig cannot stand, cannot urinate, or seems severely painful.
  • Diagnosis often starts with a physical and neurologic exam plus spinal radiographs, but advanced imaging such as CT or MRI may be needed to confirm spinal cord compression.
  • Treatment ranges from strict rest and pain control to hospitalization and referral imaging. Surgery may be considered in select severe cases, depending on location, severity, and your pig's overall health.

What Is Intervertebral Disc Disease in Pigs?

Intervertebral disc disease, often shortened to IVDD, is a problem involving the cushioning discs between the bones of the spine. When a disc degenerates, bulges, or ruptures, it can irritate nerves or compress the spinal cord. That pressure can cause pain, weakness, poor coordination, and in severe cases paralysis.

IVDD is well described in dogs, but it is much less commonly reported in pigs. In pet pigs, spinal cord disease can have many possible causes, including trauma, infection, inflammatory disease, congenital problems, and degenerative changes. Because of that, IVDD is usually considered one possible cause of back pain and hind-end weakness rather than the only explanation.

For pig parents, the important point is this: a pig that suddenly seems painful, weak in the rear legs, or unwilling to walk needs veterinary attention. Early evaluation helps your vet sort out whether the problem is a disc issue, another spinal condition, or a different cause of lameness altogether.

Symptoms of Intervertebral Disc Disease in Pigs

  • Back or neck pain
  • Reluctance to walk or stand
  • Weakness in the rear legs
  • Wobbly or uncoordinated gait
  • Dragging toes or scuffing hooves
  • Inability to stand or paralysis
  • Loss of bladder or bowel control
  • Decreased appetite or stress from pain

Some pigs are very vocal during handling, so pain can be hard to judge at home. What matters most is a change from your pig's normal movement and behavior. If your pig is suddenly weak, dragging the rear legs, falling, or unable to rise, treat that as urgent. If your pig also cannot urinate, seems panicked, or is getting worse over hours, see your vet immediately.

What Causes Intervertebral Disc Disease in Pigs?

IVDD happens when a spinal disc loses normal structure and starts to protrude or rupture. That can happen with age-related degeneration, wear and tear, or sudden force on the spine. In pigs, obesity, poor footing, jumping from furniture or ramps, and traumatic slips or falls may increase strain on the back.

Still, pigs with back pain or hind-end weakness do not always have IVDD. Your vet may also consider spinal trauma, vertebral malformations, inflammatory or infectious disease, meningomyelitis, epidural abscess, osteomyelitis, fibrocartilaginous embolism, and inherited neurologic disorders. In young pigs especially, congenital or inherited spinal and motor neuron diseases can mimic disc disease.

Because the list of look-alike conditions is long, it is safest not to assume a pig has a "slipped disc" based on symptoms alone. A careful exam and, in some cases, advanced imaging are needed to identify the most likely cause and guide treatment options.

How Is Intervertebral Disc Disease in Pigs Diagnosed?

Your vet will usually begin with a full history, physical exam, gait assessment, and neurologic exam. They will look for where the weakness is coming from, whether the problem seems painful, and whether the signs fit a spinal cord lesion versus a joint, hoof, or muscle problem. Basic bloodwork may also be recommended to look for inflammation, infection, or problems that affect anesthesia safety.

Spinal radiographs can help identify fractures, luxations, severe arthritis, vertebral abnormalities, or narrowed disc spaces, but plain X-rays cannot reliably show the spinal cord itself. If your pig has significant neurologic deficits, referral imaging may be the next step. CT can be helpful for bony changes, while MRI is generally the best test for evaluating the spinal cord, discs, and soft tissues around the spine.

In pigs, MRI has been used to investigate vertebral column disease and other neurologic conditions, and it can help separate disc-related compression from infections, inflammatory disease, vascular events, or congenital problems. Because MRI usually requires general anesthesia and specialty equipment, your vet may help you balance the value of advanced diagnostics against your pig's stability, comfort, and your care goals.

Treatment Options for Intervertebral Disc Disease in Pigs

Spectrum of Care means you have options. Here are treatment tiers at different price points.

Budget-Conscious Care

$250–$900
Best for: Pigs with mild pain, mild weakness, stable symptoms, or families starting with symptom relief before referral-level testing.
  • Office or farm-call exam
  • Basic neurologic and mobility assessment
  • Pain-control plan selected by your vet
  • Strict activity restriction with non-slip housing
  • Weight and bedding adjustments
  • Short-term recheck visit
Expected outcome: Fair to good for mild cases if the problem is inflammatory or a small disc protrusion and the pig remains able to stand and walk.
Consider: This approach may improve comfort without confirming the exact cause. It can miss serious spinal cord compression, infection, or another neurologic disease if signs worsen or fail to improve.
Most Common

Recommended Standard Treatment

$900–$3,500
Best for: Pigs with ongoing pain, worsening gait changes, repeated falls, moderate weakness, or uncertainty between spinal, orthopedic, and infectious causes.
  • Comprehensive exam and neurologic localization
  • Sedated or awake spinal radiographs when appropriate
  • Bloodwork before medications or anesthesia
  • Prescription pain control and nursing-care plan
  • Hospitalization for observation if mobility is poor
  • Referral consultation for CT or MRI if deficits are progressing
Expected outcome: Variable. Many pigs with mild to moderate neurologic deficits can stabilize or improve with rest and medical management, but outcome depends on the true diagnosis and how quickly care begins.
Consider: Provides a stronger diagnostic workup, but still may not fully define spinal cord compression without advanced imaging. Costs rise if sedation, hospitalization, or referral are needed.

Advanced / Critical Care

$3,500–$8,500
Best for: Pigs that cannot stand, have rapidly progressive weakness, have severe pain, or need definitive diagnosis before major treatment decisions.
  • Emergency stabilization and intensive pain management
  • Specialty referral or teaching hospital evaluation
  • Advanced imaging such as MRI or CT under general anesthesia
  • Urinary support and assisted nursing care if non-ambulatory
  • Discussion of surgical decompression in select cases
  • Post-procedure hospitalization and rehabilitation planning
Expected outcome: Guarded to fair, depending on whether deep pain sensation is present, how long paralysis has been present, and whether the underlying problem is surgically addressable.
Consider: Most informative and intensive option, but it requires anesthesia, specialty access, and a higher cost range. Surgery in pigs is not routine everywhere, and not every case is a good candidate.

Questions to Ask Your Vet About Intervertebral Disc Disease in Pigs

Bring these questions to your vet appointment to get the most out of your visit.

  1. Based on the exam, does this look more like spinal pain, joint disease, hoof pain, or a neurologic problem?
  2. What signs would make this an emergency, such as inability to stand or trouble urinating?
  3. Do you recommend radiographs first, or is referral for CT or MRI more useful in my pig's case?
  4. What conservative care steps should I follow at home for flooring, bedding, confinement, and lifting support?
  5. What is the expected timeline for improvement if we try medical management first?
  6. Which medications are appropriate for pain control in my pig, and what side effects should I watch for?
  7. If my pig gets worse, what would the next diagnostic or treatment step be?
  8. Is my pig a realistic candidate for referral imaging or surgery, considering size, age, and overall health?

How to Prevent Intervertebral Disc Disease in Pigs

Not every case of IVDD can be prevented, but you can reduce spinal strain. Keep your pig at a healthy body condition, since excess weight increases stress on the back and limbs. Use non-slip flooring, avoid steep ramps, and limit situations where your pig may jump off furniture, porches, or uneven surfaces.

Good housing matters too. Provide dry, well-cushioned bedding and enough space to move without scrambling on slick floors. If your pig is older or already has arthritis or weakness, traction mats and low-entry sleeping areas can make daily movement safer.

Prompt care for any new lameness, pain, or wobbliness is also part of prevention. Early treatment of minor mobility problems may help prevent falls and secondary injury. If your pig has repeated episodes of back pain or weakness, ask your vet whether weight management, environmental changes, or referral evaluation would be the most practical next step.
