Dog Suddenly Can’t Walk or Stand? What to Do Now
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 to do right now
- 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 your dog is large, very painful or difficult to move, ask the clinic for transport advice.
- Call your vet or emergency clinic. 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 with you. Bring or photograph current medicines and note any previous spinal episodes, recent falls, jumps or other changes you noticed.
What to tell the vet
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?
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 our guide to dragging back legs.
Wobbly or weak back legs
Your dog may sway, cross the hind legs, stumble or seem unusually unsteady. See the weak or 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?
Yes. 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 But 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 the veterinary team may assess
The vet may examine posture, gait if safe, limb movement, reflexes, pain, neurological function and bladder status. Depending on the examination and severity, referral or advanced imaging such as MRI or CT may be discussed. Treatment decisions depend 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

Quick questions
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.
