Several approaches can help reduce seizure frequency in dogs, ranging from daily medications to dietary changes and trigger management. Most dogs with epilepsy need at least one anticonvulsant medication, but what you do at home during and between seizures also matters significantly. The right combination depends on your dog’s seizure type, frequency, and underlying cause.
What to Do During a Seizure
Your first job is keeping your dog safe. Move breakable objects away, and if your dog is near stairs, position yourself below them to prevent a fall. Stay away from their mouth to avoid being bitten.
One technique worth knowing: gently pressing on your dog’s closed eyelids for 10 to 60 seconds can stimulate the vagus nerve, which may shorten or lessen the seizure. You can repeat this every five minutes. A small study of seven dogs found that this ocular compression technique helped abort seizures in some dogs and caused muscle relaxation in others. It’s simple, free, and something you can try while waiting for a seizure to pass.
Intense seizure activity drives up body temperature to dangerous levels. If a seizure lasts more than a couple of minutes, placing cool (not ice-cold) wet towels on your dog’s groin, armpits, and neck can help prevent overheating. A seizure lasting longer than five minutes is considered a veterinary emergency. At that point, the brain’s normal mechanisms for stopping the seizure have likely failed, and the risk of permanent neuronal damage increases significantly after 30 minutes of continuous activity. Cluster seizures, defined as two or more seizures within 24 hours, also warrant urgent veterinary care.
What to Expect After a Seizure
Nearly all dogs (97% in one survey of owners) show noticeable behavioral changes after a seizure. This recovery window is called the post-ictal phase. The most common signs are disorientation, repetitive pacing, unsteady walking, and temporary blindness. Some dogs also show unusual fear, anxiety, aggression, or seem to bark at nothing.
For about half of dogs, these signs resolve within 30 minutes. Another 20% of owners report the phase lasting 30 to 60 minutes. In some cases it stretches longer. During this time, keep your dog in a quiet, safe space where they can’t fall or bump into things. The post-ictal phase can be distressing to watch, but it resolves on its own in the vast majority of cases.
When Medication Becomes Necessary
Not every dog that has a single seizure needs lifelong medication. Veterinary guidelines recommend starting anticonvulsant treatment when a dog has two or more seizures within six months, experiences cluster seizures or a seizure lasting five minutes or longer, has prolonged or severe recovery periods after seizures, or has a known structural brain lesion or history of brain injury.
Dogs that begin seizing between ages one and five, have normal bloodwork, and behave normally between episodes are typically diagnosed with idiopathic epilepsy, meaning no underlying structural cause. A standard workup includes blood panels and bile acid testing to rule out liver disease and metabolic problems. If the picture doesn’t fit the typical pattern, your vet may recommend an MRI or spinal fluid analysis to look for brain tumors, inflammation, or infections.
Anticonvulsant Medications
Phenobarbital is the most commonly prescribed first-line seizure medication for dogs. It’s effective, inexpensive, and given twice daily. The main tradeoff is sedation, especially in the first few weeks. Your dog may seem drowsy or sluggish as they adjust. Long-term use requires periodic blood tests to check liver enzymes, since liver damage is a rare but serious risk. Some dogs also develop increased thirst, hunger, and urination.
Potassium bromide is often used alongside phenobarbital or on its own for dogs that don’t tolerate phenobarbital well. It’s given once daily and can cause nausea (giving it with food helps), increased thirst and urination, and increased appetite. Pancreatitis is an uncommon but notable risk. Bromide should never be used in cats.
Levetiracetam has become increasingly popular because it has fewer side effects than the other two options. Sedation is rare, and it doesn’t carry the same liver risks as phenobarbital. The downside is that the standard form needs to be given three times a day, which can be tough for owners with busy schedules. An extended-release version allows twice-daily dosing. Levetiracetam is also useful in emergency situations because it can be given by injection.
Many dogs end up on a combination of medications to achieve adequate seizure control. Finding the right regimen often involves adjusting doses over weeks or months based on seizure logs and blood level monitoring.
Dietary Changes That Reduce Seizures
Adding medium-chain triglyceride (MCT) oil to your dog’s diet can meaningfully reduce seizure frequency. MCTs are a type of fat that the brain can use as an alternative energy source, and they appear to have a stabilizing effect on brain activity. Clinical trials have tested diets containing 5.5% to 6.5% MCT oil across multiple veterinary practices in Europe, with dogs showing reduced seizure counts. Some studies have used supplementation equivalent to about 9% of total caloric intake from MCT oil.
You can find MCT oil at most grocery stores or buy dog foods specifically formulated with it. Start with small amounts mixed into food and increase gradually, since too much at once can cause digestive upset. This is a supplement to medication, not a replacement for it.
Watching Carbohydrate Intake
There’s growing evidence that high-glycemic carbohydrates can trigger seizures in some epileptic dogs. In documented cases, dogs that were otherwise well-controlled on a low-carbohydrate diet experienced breakthrough seizures after eating high-carb treats like pizza crust. In one case, the connection was unmistakable: seizures only occurred when family members gave carbohydrate-heavy snacks, and when the diet was strictly maintained, seizures stopped entirely. Researchers have noted that seizure control can be lost within an hour of carbohydrate exposure. If your dog has epilepsy, keeping treats low in sugar and starch is a simple precaution that may help.
CBD Oil as an Add-On Treatment
CBD has shown modest but real benefits for dogs with epilepsy that hasn’t fully responded to standard medications. In a double-blinded study of 51 dogs with drug-resistant epilepsy, those receiving CBD at 9 mg/kg per day experienced a 24.1% decrease in the number of days they had seizures, compared to a slight increase in the placebo group. The total number of seizures remained roughly stable on CBD (a 3.3% increase) versus a 30.7% increase on placebo, suggesting CBD helped prevent worsening.
These aren’t dramatic numbers, but for dogs already on multiple medications with incomplete control, a roughly one-quarter reduction in seizure days is meaningful. CBD is best thought of as an add-on therapy rather than a standalone treatment. If you’re considering it, look for veterinary-specific CBD products with clear concentration labeling, since dosing accuracy matters.
Managing Common Triggers
Seizure triggers in dogs mirror many of the same factors that affect people with epilepsy: stress, disrupted sleep, illness, and dietary lapses. In one well-documented case, a dog relapsed after being boarded for several days, returning with GI upset, then refusing food while the owner was hospitalized. The combination of stress, missed meals, and missed medication led to multiple seizures in a single day.
Practical steps that help keep seizures under control include maintaining a consistent daily routine for feeding and medication times, minimizing stressful situations like boarding when possible, keeping your dog’s sleep schedule regular, and being vigilant about what other people feed your dog. Even well-meaning family members offering the wrong treat can disrupt seizure control. Illness and medical procedures (dental work, infections) can also lower the seizure threshold, so let your vet know your dog has epilepsy before any procedure, even a routine one.
Tracking Seizures at Home
A seizure log is one of the most useful tools you can keep. Record the date, time of day, duration, what the seizure looked like (full-body convulsions versus facial twitching or staring), and anything unusual that happened beforehand, such as a dietary change, missed dose, thunderstorm, or new environment. Note how long the recovery period lasted and what signs your dog showed afterward.
This information helps your vet make medication adjustments with real data rather than rough estimates. It can also reveal patterns you wouldn’t notice otherwise, like seizures clustering around certain times of day or after specific activities. Many owners use simple spreadsheets or dedicated pet health apps to keep these records organized between vet visits.
