IVDD (intervertebral disc disease) affects the cushioning discs in a dog’s spine and can cause pain, weakness or paralysis.1 This short guide covers warning signs, treatment, recovery and where to find specialist help.
Inspired by Loui. Caring for our French Bulldog through severe IVDD, wheelchair use and daily bladder care led us to create Aubenord. This guide combines that owner perspective with the veterinary sources below.
What is IVDD in dogs?
Intervertebral disc disease affects the cushioning discs between the bones of the spine. A damaged disc can bulge or release material into the spinal canal, injuring the spinal cord or nearby nerves. The result can range from pain to weakness or paralysis. It can affect the neck as well as the back.1
Type I and Type II: a quick explanation
Hansen Type I (extrusion): material from inside the disc breaks through its outer layer, often causing sudden signs. Hansen Type II (protrusion): the outer disc bulges, often causing a more gradual problem. These are common categories, but not every disc condition fits this two-type description.4

What signs should you watch for?
Possible signs include reluctance to move, neck or back discomfort, wobbling, weakness and difficulty standing. More severe cases can involve paralysis or loss of bladder control. These changes can also have other causes, so a veterinary examination matters.1

How do vets diagnose IVDD?
Your vet examines your dog and assesses neurological function. MRI or CT may be recommended to identify the problem and help plan treatment. Severity is not something to grade from an online checklist: deep pain perception, in particular, requires professional assessment.2
What does an IVDD grade mean?
A grade describes neurological severity. Ask which scale your vet uses: the numbers are not universal. The key distinctions are whether your dog can walk independently, can still move the affected legs voluntarily, or is paralysed; in paralysed dogs, the vet also assesses deep pain perception.2
Do not test deep pain at home. Ask your vet to explain the findings and what they mean for treatment. See our plain-English stages and grades guide →

Ask your vet about referral and call the centre to confirm availability before travelling. For urgent symptoms, contact your vet or an emergency hospital immediately rather than waiting for a routine specialist appointment.
Does every dog need surgery?
No. Selected dogs may be managed with prescribed activity restriction, medication and monitoring. Surgery may be recommended for severe or worsening neurological problems, persistent pain or significant compression. The decision depends on the examination, imaging where indicated and your dog's circumstances.2
Ask your vet: Why do you recommend this option, what changes mean we should call immediately, and when should we reassess?

What does recovery involve?
Recovery often involves restricted activity, help with toileting and careful nursing. Rehabilitation and increased exercise should follow the treating team's plan. Improvement can take weeks or months; the outlook depends strongly on the severity of spinal cord injury and treatment.1, 2
Before discharge, ask for written instructions covering rest, medication, toileting, follow-up and who to contact if things change. A simple daily note can help you describe progress clearly at the next appointment.
What happens next?
Use these questions to leave each appointment with a clear plan.
| Stage | Ask your veterinary team |
|---|---|
| Assessment | What does the examination suggest, and is imaging or referral needed? |
| Treatment | Why is this option recommended for my dog? |
| Home care | Can I have written instructions for activity, medication and toileting? |
| Follow-up | When is the next review, and which changes mean I should call sooner? |
Quick answers about IVDD
Can a dog recover from IVDD without surgery?
Yes, some dogs recover with veterinary-directed conservative care. Suitability depends on neurological function, pain and progression; worsening signs need prompt reassessment.2
How long does IVDD recovery take?
Recovery can take weeks to months, and some dogs need ongoing support. Your vet should set the rest period, review dates and return-to-activity plan for your dog.3
Can IVDD happen again?
Yes. Another disc can herniate later, including after successful treatment. New pain, weakness or bladder changes need veterinary assessment.3 Read about recurrence and flare-ups →
What caring for Loui taught us
Preparing someone else to care for Loui meant making his routine clear and repeatable. That experience shapes our practical resources; it cannot predict another dog’s recovery.
Use the Daily Recovery Tracker to organise observations, or the Caregiver Handover Pack to record your vet’s instructions for someone helping at home.
