If your dog is seizing right now: stay calm, move nearby objects away so they cannot injure themselves, do not put your hands or anything else near their mouth, and time the seizure on your phone. Most seizures end on their own within one to two minutes. If it lasts longer than five minutes, or if your dog has more than one seizure within 24 hours, go to an emergency vet immediately — this is called status epilepticus and is life-threatening without treatment. After any seizure ends, keep your dog in a quiet, dim room and call your vet even if they seem fully recovered.
Witnessing a seizure in your dog can be frightening. Understanding what seizures are, how to respond safely, and when to seek emergency care helps you support your dog effectively. This guide provides educational information about canine seizures, their causes, and management approaches.
What Is a Seizure?
A seizure is a sudden, uncontrolled electrical disturbance in the brain. It may cause changes in behavior, movement, or consciousness. Seizures vary in severity from brief staring spells to full body convulsions. Most last thirty seconds to two minutes and resolve without intervention.
Recognizing Seizure Types
Generalized seizures involve the whole body: loss of consciousness, paddling limbs, jaw chomping, drooling, or loss of bladder control. Focal seizures affect one body part: facial twitching, repetitive limb movement, or unusual behavior. Post ictal phase follows: disorientation, temporary blindness, pacing, or increased thirst.
First Aid During a Seizure
Stay calm. Move furniture or objects away to prevent injury. Do not put anything in your dog's mouth. Do not restrain movement. Time the seizure. For a broader guide on handling any canine emergency, see our dog first aid emergency guide. After it ends, keep your dog quiet, warm, and in a safe space. Speak softly and avoid sudden movements. Contact your veterinarian to report the episode.
Common Causes
Causes include idiopathic epilepsy (often genetic, diagnosed after ruling out other causes), structural brain issues (tumors, trauma, stroke), metabolic disorders (liver disease, kidney failure, low blood sugar), toxins (pesticides, human medications — note that certain breeds with the MDR1 gene mutation are dangerously sensitive to common medications), infections (meningitis, distemper), and fever in puppies.
When to Seek Emergency Care
Contact a veterinarian immediately for (refer to our emergency vet signs guide for full triage levels): seizures lasting longer than five minutes, multiple seizures within twenty four hours (cluster seizures), seizures followed by prolonged disorientation or inability to stand, difficulty breathing during or after a seizure, known toxin exposure, or if this is your dog's first seizure.
