Emergency guide
Dog suddenly can’t walk or stand?
If your dog suddenly cannot walk or stand, treat it as an urgent veterinary problem. IVDD is one possible cause of sudden weakness or paralysis, but other neurological, vascular, traumatic and orthopaedic conditions can look similar. The safest next step is veterinary assessment, not trying to diagnose the cause at home.1
What matters now
If your dog cannot stand or walk, call a vet now.
Call your vet or an emergency veterinary clinic and explain the change. Ask how they want you to move and transport your dog while you arrange care.
The first things to do.
Keep the goal simple: minimise unnecessary movement and get your dog to veterinary assessment safely.
Restrict movement
Do not encourage your dog to walk, run, jump, use stairs or “try it out”. Keep movement controlled while arranging veterinary care.
Support the whole body
When lifting or moving your dog, support the chest and hindquarters together and minimise twisting. If moving them is difficult, ask the clinic for transport advice.
Call ahead
Explain when the change began, whether your dog can move each limb, whether the signs are worsening and whether they can urinate.
Take useful information
Bring or photograph current medicines and note previous spinal episodes, recent falls, jumps or other changes you noticed.
Tell the vet these six things.
You do not need to work out the diagnosis yourself. A short, factual summary can help the veterinary team understand what changed.
When you first noticed the problem and whether it appeared suddenly or progressed.
Whether your dog can stand, take any steps or move each limb.
Whether weakness or paralysis is getting worse.
Any crying out, shaking, severe pain or difficulty settling.
Any leaking urine, loss of bladder control or difficulty passing urine.
Current medicines, previous spinal or neurological episodes, and any recent fall, jump or injury you noticed.
What might you be seeing?
The pattern can help you describe the change to the veterinary team. It cannot establish the cause at home.
Cannot stand or walk
Your dog may be unable to support their weight, take normal steps or rise without falling. Sudden non-ambulatory weakness or paralysis needs urgent assessment.
Dragging the back legs
One or both hind legs may drag, scuff or fail to move normally. See the dragging back legs guide.
Wobbly or weak back legs
Your dog may sway, cross the hind legs, stumble or seem unusually unsteady. See the wobbly back legs guide.
Sudden paralysis
A sudden inability to move one or more limbs can occur with spinal cord disease, including IVDD, but there are other possible causes too.2
Pain or distress
Crying out, shaking, a tense posture, reluctance to move or being unable to settle may accompany spinal pain.
Bladder changes
Tell the vet if your dog is leaking urine, cannot urinate normally or has suddenly lost bladder control, because this can accompany neurological dysfunction.1
Could it be IVDD?
Possibly. But the symptom is not the diagnosis.
Intervertebral disc disease can cause back or neck pain, loss of coordination, weakness, inability to walk and, in more severe cases, paralysis and bladder dysfunction.1
A dog suddenly unable to walk does not automatically have IVDD. A large veterinary study of dogs presenting with acute non-ambulatory weakness or paralysis found IVDD was the most common diagnosis, while other causes were also identified.2
What this means in practice: what you are seeing tells you your dog needs assessment. It does not tell you the cause. Do not lose time trying to decide at home whether it is definitely IVDD.
What the veterinary team may assess.
The examination helps the team understand neurological function and decide what should happen next.
Examination
The vet may assess posture, gait if safe, limb movement, pain and reflexes.
Neurological status
Neurological function and bladder status help describe the severity and pattern of the problem.
Imaging or referral
Depending on the examination and severity, referral or advanced imaging such as MRI or CT may be discussed.
Treatment decision
Treatment depends on the diagnosis and neurological status rather than one symptom alone.3
Do not test “deep pain” yourself.
Deep pain perception is part of a professional neurological assessment and is important in severe spinal cord injury, but it is easy to misinterpret at home. Do not pinch toes or deliberately try to provoke pain. Let the veterinary team assess sensation safely and correctly.3 Deep pain positive vs negative explained →
If referral is recommended
Find specialist help.

Can dogs walk again after IVDD?
Outcome depends heavily on the diagnosis and neurological severity, so urgent assessment comes first.
Read the recovery guide →Four questions owners ask first.
Is a dog suddenly unable to walk an emergency?
It requires urgent veterinary assessment. Call your vet or an emergency clinic and describe the change, especially if your dog is worsening, severely painful or has bladder changes.
Can IVDD cause sudden paralysis?
Yes. IVDD can cause severe weakness or paralysis, but other conditions can cause similar signs, so a veterinary examination is needed to identify the cause.
Should I make my dog walk to test them?
No. Restrict unnecessary movement and let a veterinary professional assess mobility and neurological function.
Should I test deep pain at home?
No. Deep pain perception should be assessed by a veterinary professional because home testing can be misleading and may hurt your dog.
Trust & safety
Medical information & limitations
Aubenord provides general educational information and cannot assess your dog’s neurological function, pain, bladder or bowel function, diagnosis or treatment plan.
Follow your veterinary team’s individual advice. Sudden loss of walking ability, severe weakness or paralysis warrants urgent veterinary assessment.
How this guide is prepared
Aubenord’s IVDD content is prepared by the Aubenord Editorial Team using peer-reviewed veterinary literature, specialist guidance and reputable clinical sources.
Where owner experience is included, it is clearly separated from veterinary evidence.
