Dog Epilepsy: Symptoms & Medication Options

Epilepsy in dogs can feel frightening, especially the first time you see your dog have a seizure. Many owners understandably worry about what it means, whether it will happen again, and how their pet can be kept safe. The reassuring news is that many dogs with epilepsy can still enjoy a good quality of life with the right veterinary support and long-term treatment plan.

In this guide, we explain the common symptoms of epilepsy in dogs, how it is diagnosed, and the medication options that may help manage seizures over time. If your dog has already been diagnosed and prescribed treatment, we also outline how we can help you order medicines safely through Vetscriptions’ prescription service.

This article is intended for general guidance only and should not replace professional veterinary advice. If your pet is unwell or showing concerning symptoms, please contact your veterinary surgeon.

What is epilepsy in dogs?

Epilepsy is a condition that causes repeated seizures. A seizure happens when there is a sudden burst of abnormal electrical activity in the brain. Some dogs may have a single seizure caused by another illness or trigger, while others have ongoing seizures that fit the pattern of epilepsy.

In many cases, dogs are diagnosed with idiopathic epilepsy. This means there is no obvious structural cause, such as a brain tumour or injury, and it is often thought to have a genetic component. Epilepsy is one of the more common neurological conditions seen in dogs, and it often first appears in younger to middle-aged dogs.

Common symptoms of epilepsy in dogs

Seizures can look different from one dog to another. Some are dramatic and easy to recognise, while others are more subtle. Knowing what to look for can help you get veterinary advice promptly and give your vet useful information.

Signs before a seizure

Some dogs act differently shortly before a seizure. This can happen minutes or even hours beforehand.

• Restlessness or pacing
• Appearing anxious or clingy
• Whining
• Seeking out their owner
• Hiding or seeming unsettled

Signs during a seizure

A generalised seizure, sometimes called a full seizure, may include:

• Falling to the floor
• Stiffening of the body
• Paddling or jerking movements of the legs
• Chomping of the jaw
• Drooling
• Loss of bladder or bowel control
• Loss of awareness

Some dogs have focal seizures instead, which affect only part of the body. These may involve twitching of the face, unusual movements, staring, or odd behaviour without collapsing.

Signs after a seizure

Once the seizure has ended, many dogs go through a recovery period called the post-ictal phase. They may seem confused or unsettled for a while.

• Disorientation
• Temporary weakness
• Pacing
• Excessive thirst or hunger
• Sleepiness
• Temporary blindness in some cases

When should you contact a vet urgently?

Any first seizure should be checked by a veterinary surgeon. You should also seek urgent veterinary advice if:

• Your dog has a seizure lasting more than 5 minutes
• Your dog has repeated seizures close together
• Your dog does not recover properly between seizures
• Your dog seems unwell before or after the seizure
• Your dog has injured themselves during the episode

Repeated seizures or one prolonged seizure can be a medical emergency. Contact your veterinary practice straight away.

What causes seizures in dogs?

Not every seizure is caused by epilepsy. There are several possible reasons a dog may have a seizure, including:

• Idiopathic epilepsy
• Liver disease
• Low blood sugar
• Toxin exposure
• Kidney disease
• Head trauma
• Inflammation or infection affecting the brain
• Brain tumours, especially in older dogs

This is why proper diagnosis matters. Your vet may recommend blood tests, urine tests, blood pressure checks, and in some cases advanced imaging such as MRI scans.

How is epilepsy diagnosed?

There is no single test that confirms idiopathic epilepsy on its own. Instead, your vet will build a picture based on your dog’s age, medical history, examination findings, and test results.

You may be asked to keep a seizure diary, noting:

• The date and time of each seizure
• How long it lasted
• What the seizure looked like
• What your dog was doing beforehand
• How they behaved afterwards

If it is safe to do so, a video on your phone can also be very helpful for your vet.

Do all dogs with epilepsy need medication?

Not always. Some dogs may have very occasional seizures and may not need daily treatment straight away. In other cases, long-term medication is recommended to reduce the frequency and severity of seizures.

Your vet may consider starting medication if:

• Your dog has frequent seizures
• Your dog has cluster seizures, meaning several within a short period
• The seizures are severe or prolonged
• Your dog’s recovery is difficult
• The seizure pattern is becoming worse over time

The main aim of treatment is usually control rather than cure. In many dogs, medication helps seizures happen less often and makes them less severe.

Medication options for dogs with epilepsy

There are several anti-seizure medications that veterinary surgeons may prescribe for long-term use. The most suitable option depends on your dog’s individual needs, overall health, seizure pattern, and response to treatment.

Phenobarbital

Phenobarbital is one of the most commonly used medicines for canine epilepsy. It can be very effective, but it usually requires ongoing monitoring, including blood tests, to make sure levels stay in the right range and to check liver health.

Possible side effects may include sleepiness, increased thirst, increased appetite, or wobbliness, particularly when treatment is first started or adjusted.

Potassium bromide

Potassium bromide may be used on its own in some cases, or alongside another anti-seizure medicine. It can be helpful for certain dogs, although it may take time to reach stable levels in the body.

Levetiracetam

Levetiracetam is another anti-seizure medicine sometimes used in dogs. It may be prescribed on its own or in combination with other treatments. Some dogs tolerate it well, but dosing schedules may be more frequent depending on the product used.

Imepitoin

Imepitoin is licensed in the UK for the management of recurrent seizures due to idiopathic epilepsy in dogs. It may be recommended in certain cases and can be a suitable option for some pets.

If your dog has been prescribed epilepsy treatment, you can explore relevant dog epilepsy products and other dog prescription medicines through our website once you have a valid veterinary prescription.

Why regular monitoring matters

Long-term epilepsy treatment is not usually a set-and-forget process. Your dog may need regular check-ups and blood tests to monitor medication levels, assess organ function, and review how well the treatment is working.

It is important not to stop anti-seizure medication suddenly unless your vet specifically tells you to do so. Abrupt changes can make seizures worse.

Always give the medicine exactly as prescribed, and if you miss a dose or are unsure what to do, contact your veterinary practice for advice. If you need help understanding the ordering process, our prescription FAQs and how to order a prescription medicine page can help.

Living with a dog that has epilepsy

Although a diagnosis of epilepsy can feel overwhelming at first, many dogs do very well with long-term management. A few practical steps can make day-to-day life easier:

• Keep a seizure diary to track patterns and triggers
• Give medication at the same time every day
• Attend all recommended vet check-ups
• Make sure everyone in the household knows what to do during a seizure
• Keep your dog away from hazards such as stairs or water during recovery

If your dog also needs support in other areas of health, you can browse our wider dog collection, including dog supplements and premium supplements, where appropriate and recommended by your vet.
