Herniated discs in dogs

If your dog is suddenly reluctant to move, crying out in pain, or struggling to walk, a herniated disc could be the cause. This condition can lead to anything from back pain to serious mobility problems, including weakness or paralysis.
Because diagnosis, treatment and recovery can be costly, dog insurance may help cover some of these expenses, depending on your policy and whether the condition is pre-existing.
What is a herniated disc in dogs?
A herniated disc occurs when one of the cushioning discs between the vertebrae bulges or ruptures and begins to press on the spinal cord.
In many cases, this is linked to IVDD, a degenerative condition where discs gradually weaken over time. However, disc herniation can also occur due to acute injury.
When pressure is placed on the spinal cord, it can cause pain, nerve dysfunction, and in more severe cases, weakness, loss of coordination, or difficulty walking.
Causes of herniated discs in dogs
Most herniated discs are caused by gradual degeneration of the intervertebral discs. This process may happen over time before any symptoms appear.
Key contributing factors include:
- Age-related disc degeneration
- Genetic predisposition, especially in “chondrodystrophic” breeds (short-legged, long-bodied breeds)
- Disc calcification, which reduces flexibility and strength
- Excess body weight increasing spinal strain
- Sudden movement or trauma triggering rupture in a weakened disc
- In many dogs, the disc has already been weakening for some time before symptoms appear suddenly.
Commonly affected breeds
Herniated discs can affect any dog, but they’re most often seen in short-legged, long-bodied breeds. Some of the more commonly affected breeds include:
These breeds are more likely to develop early disc degeneration, sometimes before middle age.
Types of herniated disc
Herniated discs are often grouped into two main types:
Type I (acute extrusion)
The disc ruptures suddenly, releasing material into the spinal canal. This can cause rapid onset pain, weakness, or paralysis and is more common in predisposed breeds.
Type II (chronic protrusion)
The disc gradually bulges over time, leading to slower onset pain and progressive neurological signs.
Severity depends on how much pressure is placed on the spinal cord and whether nerve function is affected.
Symptoms of a herniated disc in dogs
The signs of a herniated disc in a dog can vary depending on its location and severity, but commonly include:
- Back or neck pain (pain is often the earliest and most consistent sign)
- Reluctance to move, jump, or climb stairs
- Arched back or stiffness
- Weakness in one or more limbs
- Wobbliness or loss of coordination
- Knuckling (dragging or misplacing paws)
- Sudden inability to walk in severe cases
- Loss of bladder or bowel control in advanced cases
What to do if your dog shows signs of a herniated disc
If you suspect a herniated disc, contact your vet immediately. A neurological examination will assess pain levels, reflexes, coordination, and limb function. Diagnosis is usually confirmed using MRI or CT imaging, which helps identify the location and severity of spinal cord compression.
Prompt treatment is important, particularly if there’s weakness or loss of movement. Early intervention is linked to better outcomes.
What age could you expect a herniated disc in your dog?
Herniated discs are most commonly seen in middle-aged to older dogs. However, in predisposed breeds, disc degeneration can begin as early as 2-4 years of age.
Symptoms may appear suddenly, even though the underlying disc changes often develop gradually over time.
How to manage a herniated disc in dogs
Management depends on the severity of the condition, but recovery usually involves rest, medication, and rehabilitation.
This may include:
- Strict rest (typically 4-8 weeks depending on how severe it is)
- Anti-inflammatory medication and pain relief
- Assisted movement and toileting support if needed
- Gradual return to controlled, lead-only exercise
- Physiotherapy and hydrotherapy to rebuild strength and coordination
- Weight management to reduce spinal strain
- Home adaptations such as ramps and non-slip flooring
Recovery can take several weeks to months, and in more severe cases may take longer.
Does pet insurance cover herniated discs?
Herniated discs are often covered by pet insurance, provided the condition is not pre-existing and your policy includes spinal or neurological cover. Treatment may involve emergency imaging, surgery, hospitalisation, and long-term rehabilitation, which can be costly.
Agria offers lifetime pet insurance, which means conditions like herniated discs can continue to be covered each year, as long as the policy is taken out before any signs or symptoms appear and is renewed annually. This is why early insurance is important, before any issues develop.
Herniated disc treatment options
Treatment for a herniated disc depends on how severe it is and whether nerves are affected. Vets may use non-surgical options for milder cases, while surgery is sometimes needed for more serious cases.
Conservative (non-surgical) treatment
This is usually used when the condition is painful but the dog can still move and use their legs:
- Strict rest (4-8+ weeks)
- Anti-inflammatory medication
- Pain management
- Controlled rehabilitation once stable
Surgical treatment
This can be recommended for severe pain, neurological deficits, or paralysis. This usually involves spinal decompression surgery to relieve pressure on the spinal cord.
When to speak to a vet
Contact your vet immediately if your dog shows signs of back or neck pain, stiffness, wobbliness, or difficulty walking. If your dog can’t walk, is crying out in pain, or loses bladder or bowel control, treat this as an emergency.
Early treatment significantly improves recovery chances and reduces the risk of long-term damage.
