A seizure can be frightening to watch, but staying calm and timing the episode can help protect your dog and give the veterinarian important information. Some seizures are brief and stop on their own. A prolonged seizure, repeated seizures, or failure to recover can become life-threatening and requires immediate emergency treatment.
If your dog has been actively seizing for about five minutes, has another seizure before recovering, or is having difficulty breathing, begin safe transportation to an emergency veterinary hospital immediately.
What Can a Seizure Look Like in a Dog?
Not every seizure looks like dramatic whole-body shaking. Seizures may be generalized or affect only part of the body.
Generalized Seizures
A dog may fall, become stiff, paddle the legs, clench the jaw, drool, vocalize, or lose bladder and bowel control. Awareness is often reduced or absent.
Focal Seizures
Focal seizures can cause repeated twitching of the face, eyelid, ear, or one limb. Some dogs make chewing movements, stare, or snap at things that are not present. A focal seizure can sometimes progress to a generalized seizure.
The Postictal Period
After a seizure, a dog may be confused, restless, temporarily unable to see, hungry, thirsty, weak, or very tired. This recovery period may last minutes to hours. Keep the environment quiet and protect the dog from stairs, furniture, other pets, and traffic.
What Should I Do While My Dog Is Having a Seizure?
- Start timing the seizure. It often feels longer than it is, and duration determines urgency.
- Clear the area. Move furniture and other objects that could cause injury when it is safe to do so.
- Keep your hands away from the mouth. Dogs do not swallow their tongues during seizures, and they may bite without awareness.
- Do not restrain the dog. Allow the seizure to run its course while preventing falls and other injury.
- Reduce stimulation. Dim lights and keep the room quiet when possible.
- Record a short video if it is safe. Video may help the veterinarian distinguish a seizure from fainting or another event.
- Follow an existing rescue-medication plan. Give medication only if it was prescribed for this dog and you have been taught when and how to use it.
Do not offer food, water, or oral medication until your dog is alert enough to swallow normally.
When Is a Dog Seizure an Emergency?
Seek immediate emergency care when:
- A seizure lasts about five minutes or longer
- Multiple seizures occur close together
- Another seizure begins before your dog has recovered
- Your dog has difficulty breathing, becomes dangerously hot, or is injured
- Your dog does not begin returning toward normal awareness
- You suspect toxin exposure, head trauma, heatstroke, or low blood sugar
- The dog is pregnant, very young, medically fragile, or has a serious underlying condition
What Is Status Epilepticus?
Status epilepticus is a seizure that does not stop on its own, commonly defined as ongoing seizure activity lasting about five minutes or more. Prolonged muscle activity can raise body temperature and contribute to brain injury, breathing problems, and other life-threatening complications.
This condition requires emergency medication and monitoring. Do not wait for a prolonged seizure to end before leaving for the hospital.
What Are Cluster Seizures?
Cluster seizures are multiple seizures occurring within a relatively short period. Even when each individual episode is brief, repeated seizures can progress to status epilepticus and may require hospitalization.
If your dog has a diagnosed seizure disorder, ask your veterinarian for a written plan covering when to give prescribed rescue medication and when to go to an emergency hospital.
Does a First-Time Seizure Require Veterinary Care?
Yes. A dog should receive veterinary evaluation after a first suspected seizure, even if the episode was brief and recovery appears complete. Contact a veterinarian promptly after your dog has recovered enough to be transported safely.
The veterinarian may recommend emergency evaluation based on the duration, recovery, dog’s age, possible toxin exposure, recent trauma, pregnancy status, or other symptoms. A first seizure in a very young or older dog can raise different concerns than a first seizure in a young adult.
What Causes Seizures in Dogs?
Seizures result from abnormal electrical activity in the brain, but many underlying problems can trigger that activity. Possible causes include:
- Idiopathic epilepsy
- Toxin or medication exposure
- Low blood sugar
- Liver or kidney disease
- Electrolyte or metabolic abnormalities
- Head trauma
- Inflammation or infection involving the brain
- A structural brain disorder, including a tumor or congenital abnormality
A seizure cannot be diagnosed or assigned a cause based on appearance alone.
Could It Be Fainting Instead of a Seizure?
Fainting, abnormal heart rhythms, balance disorders, pain episodes, tremors, and some sleep behaviors can resemble seizures. Fainting often looks like a softer collapse with faster recovery, but this distinction is not always clear.
Record the event when safe and note what your dog was doing immediately beforehand, how the episode began, limb or facial movements, gum color, duration, and recovery. This information helps the veterinarian decide which tests are most appropriate.
How Veterinarians Evaluate a Dog After a Seizure
The veterinarian will review your dog’s age, medical history, medications, potential exposures, and seizure description. Evaluation may include:
- Physical and neurologic examinations
- Blood glucose, bloodwork, and electrolyte testing
- Urinalysis or toxin testing
- Heart evaluation when fainting is possible
- Advanced imaging or spinal-fluid analysis when structural or inflammatory brain disease is suspected
How Are Seizures Treated?
Emergency treatment focuses on stopping seizure activity, supporting breathing and circulation, controlling dangerous increases in body temperature, and correcting an identifiable trigger such as low blood sugar or toxin exposure.
Long-term anti-seizure medication may be recommended based on the cause, frequency, severity, and pattern of seizures. Do not stop or change an anti-seizure medication without veterinary guidance; sudden changes can trigger serious seizure activity.
Prepare Before the Next Seizure
- Keep a log of date, time, duration, and recovery.
- Record videos when it is safe.
- Give prescribed medication on schedule.
- Know the nearest emergency hospital and your transportation plan.
- Ask whether your dog needs rescue medication for prolonged or cluster seizures.
