Epilepsy & Seizures in Dogs: What to Do
Start here
A seizure is a sudden burst of abnormal electrical activity in the brain that can cause collapse, paddling, muscle jerking, drooling or loss of awareness. During one, stay calm, keep your dog safe from stairs and furniture, don't put your hands near the mouth, and time it. A single brief seizure isn't usually an emergency, but a seizure lasting over 5 minutes, or several in a row, needs emergency veterinary care right away.
When a seizure is an emergency
Call an emergency vet immediately if:
- A seizure lasts longer than 5 minutes (status epilepticus).
- Your dog has two or more seizures in a row without fully recovering in between (cluster seizures).
- It's your dog's first-ever seizure, or you suspect poisoning, overheating or a head injury.
Prolonged seizures can dangerously overheat the body and damage the brain, so they are true emergencies.
Most single seizures stop on their own within a minute or two. What you do during and after still matters — so it helps to know the plan before it ever happens.
What to do during a seizure
It's frightening to watch, but calm, simple steps keep everyone safe:
- Don't touch the mouth. Dogs can't swallow their tongue, and you can be bitten unintentionally.
- Clear the area — move furniture, and gently guide your dog away from stairs, water or ledges.
- Dim the lights and keep noise down.
- Time it and, if you safely can, video it — this is genuinely useful to your vet.
- Afterward, speak softly and let your dog recover; many are disoriented, wobbly or clingy for minutes to hours.
Practical take: a phone video of the episode and an accurate duration are two of the most helpful things you can give your vet.
The three phases of a seizure
Seizures often follow a pattern, which can help you recognize them:
| Phase | What you might see |
|---|---|
| Pre-ictal (aura) | Restlessness, clinginess, pacing or anxiety minutes to hours before. |
| Ictal (the seizure) | Collapse, stiffening, paddling or jerking, drooling, sometimes loss of bladder or bowel control; usually under 1–2 minutes. |
| Post-ictal (recovery) | Confusion, wobbliness, temporary blindness, hunger or exhaustion, from minutes up to a day. |
Not every seizure is a full-body convulsion — some are focal, causing just facial twitching, staring or unusual repetitive behavior.
What causes seizures and epilepsy
Seizures are a sign, not a diagnosis. Causes fall into a few groups:
- Idiopathic epilepsy — the most common cause in young to middle-aged dogs (often 6 months to 6 years). No underlying disease is found, and there's often a genetic component.
- Structural brain disease — tumors, inflammation, malformation or past injury.
- Outside-the-brain causes — low blood sugar, liver or kidney disease, and toxins such as certain foods, plants, medications or recreational drugs.
Your vet works through these with a physical and neurological exam, bloodwork, and sometimes advanced imaging (MRI) or spinal fluid analysis. Idiopathic epilepsy is often a diagnosis of exclusion.
Living with and managing epilepsy
Epilepsy usually can't be cured, but it's very often well-controlled. The goal is fewer, shorter, less severe seizures — not always zero:
- Anti-seizure medication (such as phenobarbital, potassium bromide or levetiracetam) is started when seizures are frequent, severe or clustered. These are lifelong and shouldn't be stopped suddenly.
- Consistency matters — give medication on schedule, and keep up any monitoring bloodwork your vet orders.
- A seizure diary — dates, times, duration, triggers and recovery — is the single most useful tool for tuning the dose.
Because dosing decisions ride on the pattern of seizures over time, a reliable log is worth its weight in gold. It turns "he's had a few lately" into a clear frequency your vet can act on.
Keep a seizure log your vet can actually use
Tavi lets you log every seizure — date, length, what happened and recovery — plus medications and doses, and chart the frequency over time, so you and your vet can see whether treatment is working. Free for your first pet.
Frequently asked questions
What should I do if my dog is having a seizure?
Stay calm, keep your dog away from stairs, furniture and water, and don't put your hands near the mouth. Dim lights, keep quiet, and time the episode. If it lasts over 5 minutes or repeats without recovery, get emergency veterinary care immediately.
How long is too long for a dog seizure?
A seizure lasting more than 5 minutes, or several seizures in a row without full recovery between them, is an emergency. Prolonged seizures can cause dangerous overheating and brain injury, so call an emergency vet right away.
Can dog epilepsy be cured?
Idiopathic epilepsy usually can't be cured, but it's often well-managed with lifelong anti-seizure medication. The realistic goal is fewer, shorter and milder seizures rather than complete elimination, and medication should never be stopped abruptly.
What triggers seizures in dogs?
Idiopathic epilepsy has no identifiable trigger, but seizures can also stem from brain tumors or inflammation, low blood sugar, liver or kidney disease, and toxins. Some epileptic dogs seem more prone during stress, missed medication or hormonal changes; a diary helps spot patterns.
Is it painful for a dog to have a seizure?
The seizure itself isn't thought to be painful, because the dog is typically unaware during it. Dogs can be disoriented, anxious or exhausted afterward, and may injure themselves by thrashing, which is why keeping the area safe matters.
