Why Dog Seizure Happens
Dog seizures, often caused by disorders like epilepsy, result from abnormal bursts of electrical activity in the brain, disrupting normal function.
Symptoms include twitching, excessive drooling, shaking, or leg movements resembling treading water, lasting from seconds to minutes and leaving the dog temporarily disoriented.
While seizures can vary in severity, understanding their causes and seeking veterinary care can help manage the condition and ensure your pet’s well-being.
What Causes Seizures in Dogs?
Seizures in dogs can stem from various causes, including idiopathic epilepsy (often hereditary), low blood sugar, head injuries, or exposure to toxins like chocolate or antifreeze.
Conditions such as liver or kidney disease, infectious diseases like rabies and distemper, anemia, encephalitis, strokes, and brain cancer may also contribute.
Certain medications can act as triggers, making veterinary guidance crucial. Identifying the cause with your vet’s help ensures targeted care to manage the condition and enhance your dog’s quality of life.
Can Some Foods Trigger a Seizure in Dogs?
Certain human foods and beverages, like chocolate, caffeine, alcoholic drinks, and raw bread dough, can be harmful to dogs and may trigger seizures.
Products with xylitol, a toxic artificial sweetener found in toothpaste, sugar-free candies, and gums, are especially dangerous, as even small amounts can cause blood sugar drops and seizures.
Excessive salt, from sources like seawater or modeling clay, also poses risks. Preventing access to these substances and seeking immediate veterinary help if ingestion occurs is crucial for keeping your dog safe and healthy.
What Are the Symptoms of Seizures in Dogs?
Mild Symptoms: Facial tics, unusual barking, dazed look, or staring into space.
Physical Signs: Twitching muscles, excessive drooling, or chomping motions.
Severe Symptoms:
- Stumbling or falling.
- Tongue chewing or foaming at the mouth.
- Paddling motions with legs.
- Loss of control over bodily functions (peeing or pooping).
- Loss of consciousness.
Before and After Seizures:
- Nervousness, restlessness, whining, or shaking.
- Disorientation, wobbliness, or temporary blindness.
- Bumping into objects or walking in circles.
- Hiding behavior, often with drooping chin and excessive drooling.
Response Tip: Stay calm, provide a safe environment, and monitor symptoms for effective management with your vet.
How Long Do Seizures in Dogs Last?
Seizures in dogs typically last a few seconds to a few minutes, though it can feel much longer for worried owners.
Most resolve on their own, but seizures lasting more than 5 minutes are a medical emergency requiring immediate veterinary care.
Knowing the usual duration of seizures helps you act promptly to ensure your dog’s safety during and after the episode.

Types of Seizures in Dogs
Generalized Seizures (Grand Mal Seizures)
Generalized seizures involve abnormal electrical activity throughout the brain, causing dogs to lose consciousness and experience convulsions.
These seizures typically last from a few seconds to a few minutes.
Focal Seizures
Focal seizures affect specific parts of the brain, leading to unusual movements in a limb or on one side of the body.
These episodes usually last a couple of seconds.
Psychomotor Seizures
Psychomotor seizures involve strange behaviors, such as chasing imaginary objects or compulsively chasing their tail.
These episodes can last a couple of minutes and are often consistent, making them tricky to identify.
Idiopathic Epilepsy and Temporal Lobe Seizures
Associated with temporal lobe seizures, idiopathic epilepsy commonly affects dogs aged 6 months to 6 years.
Breeds like Border Collies, Australian Shepherds, Labrador Retrievers, Beagles, Belgian Tervurens, Collies, and German Shepherds are particularly prone to this condition.
Risks of Prolonged Seizures
Prolonged epileptic seizures can be dangerous, potentially causing the dog’s body temperature to rise to unsafe levels.
Managing Seizures with Medication
With proper diagnosis and anti-seizure medication, most dogs can live normal lives, even if seizures occur occasionally.
Identifying the type of seizure is key to effective management.
What Should I Do if My Dog Has a Seizure?
If your dog has a seizure, stay calm and move them away from hazards. Use a blanket to cushion them but avoid putting anything in their mouth.
Time the seizure and record a video for your vet. If it lasts over 5 minutes or occurs repeatedly, seek immediate veterinary care, as prolonged seizures can cause serious complications.
Keep your dog cool with a fan or cold water on their paws and monitor them closely after the seizure. Contact your vet if they remain unconscious or show severe symptoms. Quick action ensures your dog’s safety.
What Should I Expect When I Take My Dog to the Vet?
When you take your dog to the vet after a seizure, they will perform a thorough exam and ask about recent injuries or unusual food intake.
They may conduct blood and urine tests to assess liver, kidney, blood sugar, or electrolyte levels.
Advanced diagnostics like CT scans or MRIs might be used to check for brain abnormalities, while fluid samples could rule out infections or toxins.
If the cause is idiopathic epilepsy or another condition, the vet may prescribe medications to control seizures.
With proper diagnosis and care, most dogs can effectively manage their condition and live a better quality of life.
How Is Seizure in Dogs Treated?
- Frequency and Severity:
- Dogs with more than one seizure a month or violent seizures lasting 5 minutes or longer may require anti-seizure medications.
- Breeds like Border Collies, Golden Retrievers, German Shepherds, Irish Setters, Keeshonds, Huskies, and Saint Bernards are more prone to serious seizures and often need lifelong management.
- Common Anti-Seizure Medications:
- Levetiracetam
- Phenobarbital
- Potassium Bromide (K-BroVet)
- Zonisamide (Zonegran)
- Medications must be given as directed, as stopping them suddenly can trigger seizures.
- Managing Triggers:
- Minimize stressors like fireworks, stress, or overexertion.
- Vagal nerve stimulation can help calm the nervous system during episodes (e.g., closed eyes lasting only 10-20 seconds).
- Emerging and Alternative Treatments:
- Cannabidiol (CBD) oil: Shows promise in managing epilepsy but requires further research.
- Traditional Chinese veterinary medicine: Includes acupuncture and herbal remedies, to be performed by trained practitioners.
- Dietary Management:
- Vets may recommend prescription food enriched with medium-chain triglycerides (MCTs) to support brain health and reduce seizure activity.
- Tailored Treatment Plans: Combining traditional and alternative therapies ensures better seizure control and improved quality of life for your dog.

Conclusion
Seizures in dogs can be distressing for both pets and their owners, but understanding the causes, symptoms, and treatments can make managing them less overwhelming.
By recognizing the signs early and working closely with your veterinarian, you can ensure your furry companion receives the care they need. Whether through medication, lifestyle adjustments, or alternative therapies, most dogs can lead happy, fulfilling lives despite experiencing seizures.

FAQs
What does a seizure look like in a dog?
A seizure can present as your dog appearing to freeze, stare into space, or start to bark unexpectedly. Physical signs include drooling, paddling motions with the legs, or even foaming at the mouth.
How long does it take for a dog to recover from a seizure?
The recovery period typically lasts 1-2 minutes, but dogs can appear confused, disoriented, or experience issues like vision problems or increased thirst for up to 24 hours.
Can seizures shorten a dog’s life?
With effective treatment, most dogs with idiopathic epilepsy can have a normal lifespan. However, prolonged or frequent seizures without proper management can pose risks.
What can trigger seizures in dogs, and how can I prevent them?
Common triggers include stress, fireworks, and certain medical conditions. Techniques like vagal nerve stimulation, where the closed eyelids are gently stimulated for 10-20 seconds, can help calm the nervous system. Alternative options like acupuncture, Chinese herbal remedies, and CBD oil are also gaining popularity for seizure management.
What should I do during a seizure?
Keep your dog in a safe place away from hazards and avoid touching their mouth to prevent being bitten. If seizures last too long or occur back-to-back, diazepam (Valium) can be administered rectally, or midazolam may be given through the nostrils, as directed by a vet. In emergencies, IV diazepam at the vet can stop the seizure quickly.
