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

1
Write down the time of onset, initial symptoms, and how they have developed
2
Prepare records of food intake, water consumption, and bowel and bladder habits over the past few days
3
List all current medications, supplements, and any known allergies
4
Film your pet from the front and side: walking, standing, and lying down
5
Bring any previous test reports or imaging results if available
6
It is advisable to call ahead and book a clinic that can perform neurological assessment and imaging
