READ THIS FIRST

Observations can help your veterinarian. They cannot rule out an emergency.

Contact an emergency veterinary facility immediately for difficult breathing, collapse, ongoing seizures, inability to urinate, major bleeding, abnormal gum color, sudden severe abdominal swelling or rapidly worsening weakness.

01 · POSSIBLE CAUSES

What could be behind this symptom?

These are possibilities, not a diagnosis. The right explanation depends on the examination, species and medical history.

  • Epilepsy, toxin exposure or low blood sugar
  • Brain inflammation, trauma, stroke-like events or a mass
  • Liver disease, electrolyte changes or severe infection
  • Medication errors or an underlying metabolic disorder
02 · WHAT YOU CAN OBSERVE

What can you safely check at home?

Write down what you see and bring photographs or video only when doing so does not delay care.

  • Start and stop times, body movements, awareness and recovery
  • Whether another seizure follows before normal recovery
  • Possible toxin, medication, heat or low-blood-sugar exposure
  • A brief video only if it can be obtained safely without delaying help
03 · WHAT NOT TO DO

Avoid actions that can make things worse.

  • Do not put your hands or any object in the animal’s mouth.
  • Do not restrain limbs or attempt to stop the movements.
  • Do not offer food, water or medication during the seizure.
  • Do not delay emergency care for prolonged or repeated events.
04 · WHEN TO CALL

When should you contact your veterinarian?

  • Contact a veterinarian after any first seizure or a meaningful change in an established seizure pattern.
  • Move hazards away, dim lights and keep other animals and children back.
  • Tell the veterinary team exactly how long the event lasted and whether recovery was complete.
05 · WHEN IT IS AN EMERGENCY

Get emergency help immediately if you see:

  • A seizure lasting about five minutes or longer
  • Multiple seizures within a short period, incomplete recovery, breathing difficulty or high body temperature
  • A first seizure with possible toxin exposure, trauma, pregnancy-related illness or severe weakness

06 · SPECIES-SPECIFIC CONCERNS

The same symptom can mean different things in different animals.

Rabbits & small mammals

Low blood sugar, toxin exposure, ear/neurologic disease and severe systemic illness require urgent species-specific evaluation.

Birds

Seizures or loss of perch grip can accompany toxins, low calcium or serious metabolic disease.

Domestic equines

Keep people clear of a seizing large animal and request immediate veterinary assistance; do not attempt physical restraint.
