What to do now

A seizure episode should be timed and discussed with a veterinarian; clusters or prolonged episodes are emergencies.

Monitor

  • Time the episode and recovery period if safe.
  • Keep your dog away from stairs, furniture edges, and water.
  • Record possible toxin exposure, medications, missed doses, or previous episodes.

Call a vet

  • Call after any first seizure or any change in seizure pattern.
  • Call sooner for repeat seizures, slow recovery, or underlying illness.
  • Ask what information to bring before transport.

Emergency now

  • Use emergency care for a seizure lasting several minutes, cluster seizures, trouble breathing, or failure to recover.
  • Use emergency care after suspected toxin exposure.
  • Do not put hands near the mouth during a seizure.

Red flags

  • Seizure lasting several minutes
  • More than one seizure in a short period
  • Slow or incomplete recovery
  • Possible toxin exposure

Possible causes

These are non-diagnostic examples to help frame a veterinary conversation.

  • Epilepsy or neurologic disease
  • Toxin exposure
  • Metabolic or systemic illness

What to track before the vet

  • When signs started and whether they are getting worse
  • Appetite, water intake, and overall energy in the last 24 hours
  • Any vomiting, diarrhea, blood, collapse, or breathing changes
  • Recent food changes, new treats, medications, or toxin exposure

When to get care

Use the intake flow if you want a structured way to organize the symptom details before you contact a professional. Seek prompt care when signs are severe, worsening, repeated, or paired with breathing trouble, collapse, pale gums, pain, or inability to keep water down.
