What observations should I make first if my pet shows signs of paralysis?

Start by recording the time of onset, appetite, and toileting habits, and film your pet walking and lying down — this information helps the vet quickly identify the key tests needed.

What imaging tests are needed for paralysis?

The vet will usually start with X-rays, and may recommend CT or MRI to evaluate the spine and spinal cord if needed — further tests are determined by the vet.

What home care can I provide to help my pet recover?

Following your vet's instructions, you can help by repositioning your pet regularly to prevent pressure sores, keeping them clean, assisting with urination and defecation, and attending all follow-up appointments.

When should I go straight to an emergency vet?

If your pet has difficulty breathing, suddenly cannot move, or loses consciousness, go to an emergency vet immediately and contact your vet as soon as possible to explain the situation.

How much do the tests and treatment usually cost?

Costs vary by clinic and region — ask your vet for an estimate before proceeding.

Paralysis in Dogs & Cats: Symptoms, Neurological Exam & Care Guide [2025]

Paralysis in pets can be caused by intervertebral disc disease, spinal cord lesions, vascular embolism, and more — imaging is needed to confirm the cause and guide treatment.

When to See a Vet

Seek immediate veterinary care (emergency)

•Sudden whole-body or hind-limb weakness with collapse and no movement
•Breathing becomes very labored or markedly rapid
•Sudden loss of consciousness or brief fainting without recovery

Schedule a veterinary visit soon (within 24–72 hours)

•Unsteady walking with frequent falling or dragging
•Marked weakness with persistent inability to stand normally
•Pain response when the spine or limbs are touched

01What symptoms indicate something is wrong?

Paralysis or pronounced weakness is a common sign of neurological problems; it may affect only some limbs or overall mobility, and is usually accompanied by changes in gait and abnormal pain responses.

Obvious weakness in the hind or front limbs, unable to stand or walk normally
Unsteady gait, frequent stumbling, dragging limbs, or inability to bear weight
Flinching or pain response when the spine or limbs are touched
Decreased activity level, lethargy, or noticeable changes in appetite
Difficulty urinating or defecating, or loss of bladder and bowel control

Seek emergency care immediately if you notice the following symptoms:

⚠️ Sudden hind limb collapse or complete inability to move
⚠️ Breathing difficulty or rapid breathing
⚠️ Loss of consciousness or brief collapse

02How to assess the situation at home: key observations and emergency criteria

Observing and recording key information at home helps the vet quickly understand your pet's condition and prioritise the necessary tests.

Record when symptoms started and how they have progressed (note exact times)
Track changes in appetite, water intake, and daily food consumption
Note urination and defecation frequency and any abnormalities
Film your pet walking, standing, rolling over, and lying down with your phone
Weigh your pet weekly and record the numbers to track changes
If symptoms worsen, promptly book a clinic that can perform a neurological assessment

03How will the vet diagnose the problem? Common diagnostic tests

At the clinic, the vet will focus on a neurological assessment, supported by blood tests and imaging to confirm the cause and extent of the problem.

Full neurological examination

reflexes, sensation, and muscle strength assessment

X-rays

initial evaluation of spinal structure and thoracic cavity

Blood tests

including blood glucose and basic biochemistry to rule out systemic causes

ECG or cardiac ultrasound

to rule out cardiopulmonary involvement

Advanced imaging (CT or MRI)

to assess spinal cord or nerve compression

If needed, referral to a specialist hospital with advanced imaging equipment

04Treatment and care after diagnosis: medications, diet, and home care guide

Treatment is tailored to the diagnostic findings, and close monitoring of neurological function and overall condition is essential after surgery or medication.

Develop a medical, surgical, or interventional treatment plan based on diagnostic results
Attend scheduled follow-up appointments to assess symptom changes and adjust treatment
Monitor diet and weight management in line with your vet's dietary recommendations
Home care includes repositioning your pet, preventing pressure sores, and assisting with urination and defecation
Schedule periodic imaging or neurological assessments to monitor recovery
If needed, arrange physiotherapy or a neurology specialist review to support functional recovery

05What to prepare before the vet visit: key information to help diagnose the cause quickly

Write down the time of onset, initial symptoms, and how they have developed

Prepare records of food intake, water consumption, and bowel and bladder habits over the past few days

List all current medications, supplements, and any known allergies

Film your pet from the front and side: walking, standing, and lying down

Bring any previous test reports or imaging results if available

It is advisable to call ahead and book a clinic that can perform neurological assessment and imaging
