Watching your dog have a seizure is frightening, but the most important thing you can do is stay calm, keep your hands away from their mouth, and make the area around them safe. Most seizures last under two minutes and end on their own. Your job in that moment is to protect your dog from injury, not to stop the seizure itself. What happens after the seizure, and how you work with your vet long-term, matters just as much as those first critical minutes.
What to Do During a Seizure
When your dog starts seizing, clear away anything nearby they could hit or knock onto themselves: furniture edges, hard objects, water bowls. If they’re near stairs, position yourself below them on the steps to prevent a fall. Move other pets and children out of the room.
Keep your hands away from your dog’s mouth. Dogs do not swallow their tongues during seizures, and a seizing dog has no control over their jaw muscles. Bites during seizures are common and unintentional. Your instinct will be to hug or stroke your dog’s head, but they’re completely unaware of their surroundings during a seizure, and touching them won’t provide comfort. It only puts you at risk.
Start timing the seizure as soon as you notice it. Use your phone’s stopwatch. This number is one of the most useful pieces of information your vet will ask for. If the seizure lasts longer than five minutes, get to a veterinary clinic immediately. Prolonged seizures (called status epilepticus) can cause brain damage and are a medical emergency.
Caring for Your Dog After a Seizure
The period after a seizure, known as the postictal phase, can last anywhere from a few minutes to several hours. During this time your dog may seem disoriented, pace aimlessly, bump into walls, or appear temporarily blind. Some dogs are ravenously hungry or extremely thirsty. Others become unusually aggressive, not out of temperament but out of confusion. Give your dog space. Speak softly. Keep the room dim and quiet, and block access to stairs until they’re fully steady on their feet.
Don’t offer food or water until your dog is clearly alert and coordinated enough to swallow safely. Once they’ve returned to normal, let them rest. Many dogs sleep heavily after a seizure, and that’s fine.
Keeping a Seizure Log
A detailed log is one of the most valuable tools you can bring to a vet appointment. For each seizure, record the date, time it started, how long it lasted, and what your dog’s body did (full-body convulsions, twitching on one side, paddling legs). Note anything unusual that happened in the hours before: a change in diet, a stressful event, a missed medication dose. Also record how long the recovery period lasted and any unusual behavior during it.
This information helps your vet spot patterns, evaluate whether medication is working, and decide when to adjust treatment. Some veterinary research teams have even developed digital seizure diary apps that let owners log events and share data directly with their neurologist.
Why Dogs Have Seizures
Seizures happen when electrical activity in the brain fires abnormally and rapidly. The most common cause in dogs is idiopathic epilepsy, a genetic condition with no identifiable underlying disease. The majority of epileptic dogs have their first seizure between ages 1 and 5. Dogs in that age range are most likely to receive an epilepsy diagnosis, although roughly one-third of dogs between 1 and 5 will turn out to have a structural or metabolic cause instead, such as a brain tumor, inflammation, liver disease, or low blood sugar.
Because seizures can signal something serious, your vet will typically run blood work, a urinalysis, and a biochemical panel to check for organ problems or toxin exposure. If those come back normal and seizures continue, the next step is often an MRI to look for structural issues in the brain. Dogs need general anesthesia for an MRI, and the total cost (including the exam, blood work, anesthesia, and imaging) averages around $5,000 at specialty neurology practices. Cerebrospinal fluid analysis may also be recommended to rule out infections or inflammation. Idiopathic epilepsy is diagnosed by excluding all of these other causes.
Medications for Seizure Control
Most dogs with recurring seizures are placed on daily anti-seizure medication. Phenobarbital is the most widely prescribed first-line option. It’s given twice daily, and your vet will monitor blood levels periodically to make sure the drug is in an effective range without reaching toxic levels. The right dose varies significantly between dogs because individual animals metabolize the drug differently. Some dogs do well on a low dose while others need considerably more.
Potassium bromide and levetiracetam are other commonly used options, sometimes given alone and sometimes combined with phenobarbital when seizures aren’t fully controlled by one drug. Finding the right medication or combination takes patience. Your vet may need to adjust doses several times over weeks or months, guided by blood tests and your seizure log. The goal is usually to reduce seizure frequency and severity rather than eliminate seizures entirely, though some dogs do become seizure-free on medication.
Rescue Medications for Emergencies
If your dog has cluster seizures (multiple seizures within 24 hours) or a history of prolonged episodes, your vet may prescribe a rescue medication to keep at home. These are fast-acting sedatives from the benzodiazepine family, designed to stop a seizure that’s happening right now or prevent additional ones from clustering together.
The two most common options are rectal diazepam and intranasal midazolam. Rectal diazepam is given via a pre-filled syringe or suppository. Intranasal midazolam is sprayed into the nose using a small atomizer device. Midazolam is roughly five to six times more potent than diazepam, so it’s given in smaller volumes. Your vet will show you exactly how and when to administer whichever rescue medication they prescribe. Having one on hand can be the difference between managing a cluster at home and an emergency vet visit.
Diet and Supplements
Some dietary approaches show promise as add-ons to conventional treatment. Medium-chain triglyceride (MCT) oil, the same type of fat found in coconut oil, has been studied in dogs with idiopathic epilepsy. When MCT oil was supplemented at about 9% of a dog’s daily calorie needs, researchers observed a reduction in seizure frequency along with measurable increases in ketone levels in the blood. Ketones are an alternative fuel source for the brain, and higher ketone levels appear to have a stabilizing effect on neural activity.
CBD-rich hemp extract has also been tested in clinical trials. In a randomized crossover study published in Frontiers in Veterinary Science, dogs receiving 2 mg/kg of a CBD-rich extract every 12 hours experienced an average drop in seizure frequency from 8 seizures during the placebo period to 5 seizures during treatment. Nearly half the dogs on the extract saw their seizure count drop by 50% or more, compared to none on placebo. Importantly, these dogs were already taking conventional anti-seizure medications, so CBD was used as an additional therapy, not a replacement.
If you’re considering MCT oil or CBD, talk to your vet first. Both can interact with anti-seizure drugs and may require dose adjustments or additional liver monitoring. Quality and concentration vary wildly between products, so veterinary guidance on sourcing matters.
What Long-Term Management Looks Like
Living with an epileptic dog means building routines. Medication needs to be given at consistent times every day. Blood work to check drug levels and liver function is typically done every 6 to 12 months, or more frequently when starting a new medication. Your seizure log becomes a running conversation with your vet about whether the current plan is working.
Most dogs with well-managed epilepsy live full, happy lives. Seizure frequency often stabilizes once the right treatment plan is in place, and many owners find that the condition becomes a manageable part of their dog’s care rather than a constant crisis. The first few months after diagnosis tend to be the hardest, as you and your vet dial in the right medication and dose. It gets easier from there.
