Dog dragging back legs: warning signs and what to do

What does “dragging the back legs” look like?

These signs can reflect pelvic-limb ataxia, weakness (paraparesis) or, in more severe cases, paralysis. Thoracolumbar IVDD is a recognised cause of these neurological signs in dogs.^1,2

Could dragging back legs be IVDD?

Yes. When disc material compresses or injures the spinal cord, dogs can develop back pain, poor coordination, weakness or paralysis of the hind limbs, and sometimes bladder dysfunction.^1,2 But IVDD is not the only possible cause of sudden hind-limb weakness or paralysis. Veterinary emergency data show that other neurological and vascular disorders can also cause acute loss of mobility.³

What to do now

1. Restrict unnecessary movement. Do not encourage running, jumping, stairs or repeated walking tests.
2. Support your dog carefully. Keep the body controlled when moving them. If they are large, very painful or difficult to lift, ask the veterinary team how they want you to transport them.
3. Call your vet. Tell them when the dragging started, whether one or both legs are affected, whether your dog can stand, whether signs are worsening, whether pain is present and whether they can urinate normally.
4. Bring relevant history. Mention any previous IVDD or spinal episode, current medication, recent injury, fall or jump, and when your dog last walked normally.

When is it more urgent?

Urgency increases when neurological function is being lost. A dog that progresses from scuffing or wobbling to being unable to stand or walk, develops severe pain, or develops urinary problems needs prompt veterinary attention. Acute thoracolumbar IVDD can range from pain and mild weakness to paraplegia and urinary dysfunction.^1,2

What may the vet check?

A veterinary examination may assess gait, limb strength, paw positioning, spinal pain, reflexes and other neurological findings to help localise the problem. Depending on the examination and severity, referral and advanced imaging such as MRI or CT may be discussed. The ACVIM consensus statement notes that MRI, CT and related imaging approaches are used to diagnose acute thoracolumbar disc extrusion and assist treatment planning.¹

Finding specialist help

If your vet recommends neurological or spinal referral, use the UK IVDD specialist directory or the USA IVDD specialist directory. If your dog is deteriorating now, contact a veterinary service first rather than waiting to arrange a directory referral yourself.

Frequently asked questions

Why is my dog dragging their back legs?

Dragging can happen when the hind limbs are not being controlled normally. IVDD is one possible neurological cause, but an examination is needed because several spinal, neurological, vascular, traumatic and orthopaedic problems can produce similar signs.

Is a dog dragging its back legs an emergency?

Sudden or worsening dragging is more concerning, particularly if your dog cannot stand or walk, is severely painful or has urinary problems. Contact a veterinary professional promptly for triage advice.

Can IVDD cause a dog to drag its back legs?

Yes. Thoracolumbar IVDD can cause pelvic-limb incoordination, weakness and paralysis when the spinal cord is affected.^1,2

Should I make my dog walk to see how bad it is?

No. If a spinal problem is possible, avoid repeatedly testing walking, stairs or jumping. Keep movement controlled and seek veterinary guidance.
