Intervertebral Disc Disease (IVDD)
Intervertebral disc disease (IVDD) is the most common spinal problem we work with at AURA. Caught early and managed well, many dogs walk again. Here is what IVDD is, how it shows up, and how rehabilitation supports the recovery your vet is guiding.
Quick facts
- What it is: a soft cushion sitting between two bones in your dog’s spine has slipped, swollen, or burst. The cushion now presses on the spinal cord.
- Who tends to be affected: dogs whose body shape carries the wear earlier in life, alongside dogs of any shape after a sudden injury or with age.
- Common signs: back pain, reluctance to jump, a wobble in the back legs, and in worse cases a sudden inability to walk.
- Outlook with rehabilitation: every animal is different. Many regain meaningful function with the right care and enough time. Your vet is best placed to set expectations for your dog.
- Time matters: a dog who cannot walk needs to see a vet within hours, not days.
What IVDD actually is, in plain words
If it helps to picture this, think of your dog’s spine as a row of small bones stacked one on top of the other. Between every two bones sits a soft cushion. The cushion gives the spine its bend and absorbs the load when your dog walks, jumps, or twists. Running down the centre of the whole stack, through a narrow tunnel inside the bones, is the spinal cord. The cord carries every signal between your dog’s brain and the rest of the body.
IVDD is what happens when one of those cushions stops behaving. It can swell out of place, slip, or burst. The cushion material then sits where it should not, pressing on the spinal cord. The cord does not tolerate that pressure well. That is where the pain comes from. If the pressure is greater, signals between the brain and the back legs (or sometimes the front legs, depending on where in the spine the problem is) struggle to get through. That is when a wobble, weakness, or paralysis appears.
The spine, in 60 seconds
The spine runs from your dog’s skull to the tail. It is built from about 50 bones (vertebrae), give or take a few depending on the tail. Each vertebra protects part of the spinal cord, and each pair of vertebrae is joined by one of those cushions.
The spinal cord itself ends about two-thirds of the way down the back. The nerves that supply the back legs leave the cord through small gaps between the vertebrae in the mid and lower spine. The nerves for the front legs come out higher up, in the neck and shoulders.
Where in the spine the disc fails changes what you see. A problem in the neck affects the front legs first, often with sharp pain. A problem in the mid back affects the back legs, which is the picture most owners have in mind when they hear “IVDD”.
Why some animals are more prone
We are careful at AURA never to pin a condition on a breed. Every dog we have worked with has its own story, and many of the loveliest patients we see are dogs nobody would have expected to develop IVDD.
That said, the science is clear on one pattern. Dogs whose body shape carries a long back and short legs have spinal discs that age faster than the average. The technical term for this body type is “chondrodystrophic”. It is not the breed name that matters; it is the inherited body shape, and the disc biology that comes with it. Several breeds carry this shape, and you will often hear them named in the same breath as IVDD. The reverse is also true. A dog of any shape can develop IVDD after a sudden injury, with age, or for reasons that are not always fully understood.
If your dog has that long back and short leg shape, treat it as a reason to be observant, not anxious. Most dogs with that shape never develop IVDD. What changes is how you respond to the early signs we describe further down.
How IVDD is graded (1 to 5)
When your vet examines your dog, they will usually place the case into one of five grades. The grades describe how severely the spinal cord is being affected. They help everyone (you, your vet, and us at AURA) make sensible decisions about treatment and expectations. The plain-language version is below. Your vet will explain the grade specific to your dog after examining them.
Your dog is painful but still walking normally. Reluctance to jump, a hunched posture, a yelp when picked up.
Strict rest, pain medication from your vet, and a gentle rehabilitation start once your vet clears it.
Most dogs at this grade settle within a few weeks with good rest and medication.
Pain plus mild loss of coordination in the back legs. The dog can walk but stumbles or knuckles.
Rest, pain control, and a structured rehabilitation plan. Your vet may also discuss imaging or surgical options.
Many dogs at this grade do well with conservative care and rehabilitation.
The dog cannot stand or walk on its own but can still move the legs when supported.
Most vets recommend imaging (X-ray or MRI). Surgery is often discussed. Rehabilitation begins as soon as your vet allows.
Time to treatment matters more at this grade. Your vet is best placed to set expectations.
The dog cannot move the back legs but still responds to a firm pinch between the toes. Bladder control may be affected.
Surgery is usually recommended, followed by structured rehabilitation.
With prompt surgical care and committed rehabilitation, many dogs at this grade regain meaningful function. Your vet has the full picture.
The dog cannot move the back legs and does not respond to deep pinch testing.
Treated as an emergency. Surgery within the first 24 to 48 hours gives the best chance of recovery. Rehabilitation follows once your vet has cleared the dog for it.
Outcomes vary significantly. Speed of treatment and the dog’s individual response both play a role. Your vet is best placed to advise on what your dog’s specific picture means.
The grade is not a forecast. It is a description of today. Your vet will reassess as the picture changes.
What can trigger a flare
A few moments are common culprits we hear about often. None of these guarantee a flare, and a flare can happen without any of them. Worth knowing all the same.
- Jumping off furniture (sofas, beds, into the car)
- Twisting suddenly during play
- Slipping on a wet or polished floor (a common one in Singapore homes with tiled flooring)
- Running on stairs
- Carrying excess weight, which loads the spine across years rather than seconds
- Cumulative wear that none of us see
If your dog already has a history of IVDD, the working principle is to lower the spike risk: ramps instead of jumps, traction on slippery floors, weight kept in a healthy range, and the rehabilitation plan kept up rather than stopped at the first sign of improvement.
Signs to watch for
Some signs are loud. Others are quiet enough that you only spot them looking back. The earlier you notice, the more options you have.
Worried about a sign you have seen?
A short message tells us a lot. We will say whether it sounds urgent and what we would do next.
IVDD or something else?
Three different problems can look identical on day one. That is why your vet runs through a careful examination before anyone talks about a treatment plan. The table below sketches the patterns. It is not a diagnostic tool, it is a way to follow what your vet may be thinking.
| What you might see | IVDD | FCE (spinal stroke) | Arthritis |
|---|---|---|---|
| How it starts | Sometimes sudden, sometimes building over weeks. | Very sudden, often during a normal moment of play or a jump. | Slow, building over months and years. |
| Pain | Usually present, sometimes severe. | Usually no pain after the first moment. | Often present, worse after rest, eases with gentle movement. |
| Which legs | Both back legs together is the common pattern. | Often one side of the body more than the other. | Both back legs, often unevenly. |
| Bladder control | Can be affected in worse cases. | Sometimes affected. | Almost never affected. |
| Time of day | Worse with movement and at night. | Static, what you see is what you get from the moment it happens. | Worse in the morning, eases as the dog moves. |
Your vet uses the pattern of signs together with a neurological examination, and sometimes imaging, to tell them apart. Treatment paths differ, so the diagnosis matters.
How AURA helps with IVDD recovery
Whether your dog has had surgery or is being managed conservatively, rehabilitation is the bridge between intact nerves and useful movement. The plan is built around the dog in front of us, not around the diagnosis on the file.
The four modalities below are the ones we draw on most often for IVDD. In practice, the mix shifts week by week as your dog improves.
What recovery actually looks like
Recovery is rarely a straight line. The honest answer about timeline is that it depends on the grade, on whether surgery was involved, and on how the individual dog responds. What we can describe is the shape of the work.
Acute phase (first 1 to 2 weeks)
Strict rest, pain control from your vet, gentle hands-on work to keep joints moving without loading the spine. The job here is to let the inflammation settle without losing too much muscle.
Subacute phase (weeks 2 to 6)
Rehabilitation starts in earnest. Underwater treadmill at low water level, targeted physiotherapy, laser sessions. Short sessions, frequent rest. The dog tells us how fast to move.
Strengthening (weeks 6 to 12)
Load increases in measured steps. More walking, more controlled exercise. We build back the muscle that protects the spine for the long run.
Maintenance (ongoing)
A spaced-out plan to keep the spine supported and the dog active. Home exercises that fit your routine. Weight watch. Regular check-ins.
Long-term outlook, and your vet’s lead
Most dogs with IVDD do well with the right care. The milder grades often return close to normal life with rest, medication, and a structured rehabilitation plan. Surgical cases recover more variably. Outcome depends on how severe the original injury was, how quickly surgery happened, and how committed the rehabilitation is afterwards.
Recurrence is real. A dog who has had IVDD once is more likely to have it again, in the same disc or in another. Steady weight, traction at home, careful jumping, and ongoing core strength all reduce that risk meaningfully.
One thing to be clear about: we are not your dog’s vet. Everything on this page is general guidance built from clinical rehabilitation experience and published research. Your vet has the X-rays or MRI, the full history, and the hands-on neurological examination. When the decisions need to be made, whether to operate, when to start rehabilitation, what medication suits, when to allow stairs again, your vet’s advice always wins. We work alongside your vet, never in place of them.
Common questions about IVDD
Will my dog walk again?
If your dog still has deep pain sensation when first seen by a vet, the chance of meaningful recovery with the right care is high. Cases that have lost deep pain are harder, not always hopeless. Time and rehabilitation quality both matter. Your vet will be specific about your dog’s picture.
Do we have to do surgery?
Not always. The milder grades (1 and 2) often manage well with rest, pain control, and rehabilitation. The more severe grades (4 and 5) usually need surgical decompression. The call belongs to your vet, or a referral neurologist, after they have examined your dog and looked at imaging.
How soon after surgery can rehabilitation start?
Often within days. Gentle hands-on work begins almost immediately. Hydrotherapy is usually introduced once the surgical site is fully healed, often 2 to 3 weeks after the operation, depending on your vet’s clearance.
Can IVDD come back?
Yes. The same disc can herniate again, and other discs in the same spine can also fail later. The right rehabilitation plan, careful weight control, traction on slippery floors, and avoiding high-impact activity all reduce that risk significantly.
What does a rehabilitation session cost?
An assessment is the first step. After that, we price sessions individually or as a recovery package shaped to your dog. Send us a WhatsApp message at +65 8780 0060 with your dog’s situation, and we will quote based on what they need.
