Dog Wobbly or Weak in the Back Legs: What to Do
If your dog is suddenly wobbly or weak in the back legs, arrange veterinary assessment. An unsteady hind-limb gait can come from neurological, orthopaedic, muscular or other medical problems. IVDD is one possible cause, especially when weakness appears suddenly, worsens, or occurs with back or neck pain.1

What “wobbly back legs” can look like
Swaying or poor balance
The back end may sway from side to side or your dog may look “drunk” or poorly coordinated while walking.
Crossing or wide-stepping
The hind legs may cross over each other, step unusually wide or seem slow to correct their position.
Scuffing or knuckling
Back nails may scrape the floor, paws may turn under, or the tops of the feet may briefly contact the ground.
Weakness when rising
Your dog may struggle to stand, sit down after a few steps, slip, fall or seem unable to support the rear of the body normally.
Wobbly and weak are not exactly the same
Dogs can show both poor coordination and weakness at the same time. A veterinary neurological and physical examination is needed to work out where the problem is coming from.
Could IVDD cause wobbly back legs?
Yes. When intervertebral disc material compresses or injures the spinal cord, dogs can develop pelvic-limb incoordination (ataxia), weakness (paraparesis) and, in more severe cases, loss of walking ability.1 The ACVIM consensus statement on acute canine thoracolumbar disc extrusion also describes neurological deficits ranging from pain and ataxia through to paralysis and urinary dysfunction.2
What to do now
- Keep movement controlled. Avoid running, jumping, stairs and repeated “test walks” while you arrange veterinary advice.
- Prevent slips and falls. Keep your dog on a stable, non-slip surface. Use rugs or runners on slippery floors if needed, and prevent access to stairs or furniture while you arrange veterinary advice.
- Call your vet. Explain when the wobbliness started, whether it is worsening, whether there is pain, whether either paw is knuckling or dragging, and whether urination is normal.
- Note the progression. If you already have a short video, or can capture one without encouraging extra walking, it can be useful to show the veterinary team. Do not make your dog walk repeatedly just to record it.
What not to do
- Do not force extra walking to see whether your dog “warms up”.
- Do not start stretching, massage or rehabilitation exercises before the cause is understood.
- Do not assume a new wobbly gait is simply ageing.
- Do not pinch toes or try to test “deep pain” at home. That assessment belongs with a veterinary professional.
If the signs progress
If wobbliness becomes dragging of the back legs, your dog can no longer stand or walk, or you notice marked pain or bladder changes, use our IVDD emergency signs guide and seek veterinary assessment urgently.
What may happen at the vet
The veterinary team may assess gait, limb strength, paw placement, spinal reflexes, pain and bladder function. Depending on the findings, they may discuss referral or advanced imaging. These examinations help distinguish spinal cord disease such as IVDD from other neurological, orthopaedic or systemic causes.
What to tell the vet
- When you first noticed the wobbliness and whether it started suddenly or gradually.
- Whether one or both back legs are affected.
- Any crossing, scuffing, knuckling, dragging or falls.
- Any signs of pain, reluctance to move or difficulty getting comfortable.
- Whether urination and bowel movements are normal.
- Any recent fall, jump, injury or previous spinal/IVDD episode.
- A short gait video if you already have one or can capture it safely without making your dog walk repeatedly.
Frequently asked questions
Why is my dog suddenly wobbly in the back legs?
There are several possible causes, including neurological and orthopaedic problems. IVDD is one possibility, but the symptom alone cannot diagnose the cause. Sudden or worsening weakness warrants veterinary assessment.
Can a dog with IVDD still walk?
Yes. Some dogs with IVDD remain able to walk but become painful, weak or poorly coordinated. The severity varies, which is why a change in gait should be assessed rather than waiting for complete loss of walking.
Should I walk my dog if the back legs are wobbly?
Do not encourage extra walking or exercise to test the problem. Keep movement controlled and ask your veterinary team what level of activity is appropriate until the cause is known.
