what does a dog seizure look like


Epilepsy is a neurological condition that affects dogs, just as it affects humans. Abnormal electrical activity in the brain causes a seizure to happen. This article aims to educate pet owners on what a dog seizure looks like, the different types of seizures, causes, symptoms, diagnosis, treatment, management, complications, and prevention of canine epilepsy.

Types of Seizures

There are two main types of seizures that dogs can experience: generalized seizures and partial seizures. Generalized seizures are the most common type of seizures seen in dogs and can be further divided into tonic-clonic seizures and absence seizures. Tonic-clonic seizures, also known as grand mal seizures, involve the dog losing consciousness and experiencing muscle rigidity followed by muscle spasms. Absence seizures, also known as petit mal seizures, involve the dog briefly losing awareness and staring into space.

Partial seizures, also known as focal seizures, occur when abnormal electrical activity is confined to one area of the brain. They can be further divided into simple partial seizures, complex partial seizures, and secondary generalized seizures. Simple partial seizures involve twitching or jerking of a specific body part, such as the face or leg. Complex partial seizures involve altered consciousness, such as the dog appearing confused or disoriented. Secondary generalized seizures start as partial seizures but then spread to involve the whole brain.

Causes of Seizures in Dogs

Dogs can have seizures due to various causes. Some of the most common include genetic factors, head trauma, infections, toxins, metabolic disorders, and idiopathic epilepsy. Idiopathic epilepsy is the most common cause of seizures in dogs and is characterized by seizures that occur without a known cause.

Genetic factors can play a role in some breeds of dogs. Certain breeds, such as the Belgian Tervuren, Australian Shepherd, and Beagle, have a higher incidence of epilepsy. Head trauma can also cause seizures in dogs. Infections, such as meningitis or encephalitis, can lead to seizures. Exposure to toxins, such as lead or certain pesticides, can cause seizures. Metabolic disorders, such as hypoglycemia or liver disease, can also lead to seizures.

Symptoms of a Seizure

A seizure in a dog can be divided into three phases: the pre-ictal phase, the ictus phase, and the post-ictal phase. The pre-ictal phase occurs before the seizure and can last anywhere from a few seconds to several hours. During this phase, the dog may appear restless, anxious, or agitated. They may seek out their owner’s attention or appear to be seeking a safe place to hide.

The ictus phase is the seizure itself. During this phase, the dog may experience muscle rigidity, muscle spasms, loss of consciousness, or altered consciousness. They may vocalize or drool excessively. The seizure can range from lasting a few seconds to lasting several minutes.

The post-ictal phase occurs after the seizure and can last anywhere from a few minutes to several hours. During this phase, the dog may appear confused or disoriented. They may appear to be blind or deaf temporarily. They may be unsteady on their feet or have difficulty standing up.

Diagnosing Canine Epilepsy

If your dog experiences seizures, it’s important to take them to a veterinarian for a thorough examination. The veterinarian will perform a physical examination, blood tests, urine tests, and may recommend an electroencephalogram (EEG), magnetic resonance imaging (MRI), or cerebrospinal fluid analysis. These tests can help determine the cause of the seizures and help the veterinarian make a proper diagnosis.

Treating Canine


Treatment for canine epilepsy can include medication, changes in diet or lifestyle, and alternative therapies. The goal of treatment is to reduce the frequency and severity of seizures.

Medication is typically the first line of treatment for canine epilepsy. Anticonvulsant medications, such as phenobarbital or potassium bromide, can be effective in controlling seizures. However, these medications may have side effects, and it may take some trial and error to find the right medication and dosage for your dog.

Dietary changes may also be recommended to help manage seizures. Some dogs with epilepsy may benefit from a ketogenic diet, which is high in fat and low in carbohydrates. This type of diet has been shown to help reduce seizures in some dogs with epilepsy.

Alternative therapies, such as acupuncture or chiropractic care, may also be helpful in managing seizures in dogs. However, it’s important to discuss these options with your veterinarian before trying them.

Managing Canine Epilepsy

Managing canine epilepsy involves monitoring your dog’s seizures and making any necessary adjustments to their treatment plan. It’s important to keep a record of your dog’s seizures, including the date and time of the seizure, the length of the seizure, and any unusual behaviors exhibited during the seizure or post-ictal phase.

Regular check-ups with your veterinarian are also important to monitor your dog’s condition and make any necessary adjustments to their treatment plan. Your veterinarian may recommend periodic blood tests or other diagnostic tests to monitor your dog’s response to medication.

Complications of Canine Epilepsy

Seizures can be dangerous for dogs, particularly if they occur while the dog is near water or other hazards. Additionally, prolonged seizures, or status epilepticus, can be life-threatening and require immediate veterinary attention.

Long-term use of anticonvulsant medications can also have side effects, such as liver damage or decreased blood cell production. It’s important to discuss the potential risks and benefits of medication with your veterinarian.

Preventing Canine Epilepsy

While it’s not always possible to prevent seizures in dogs, there are some steps that pet owners can take to help reduce the risk of seizures. These include:

  • Keeping your dog up to date on vaccinations and parasite prevention
  • Avoiding exposure to toxins, such as pesticides or household cleaners
  • Feeding your dog a high-quality diet and maintaining a healthy weight
  • Minimizing stress and anxiety in your dog’s environment


Canine epilepsy can be a frightening and confusing condition for pet owners. However, with proper diagnosis, treatment, and management, most dogs with epilepsy can lead happy and healthy lives. By understanding what a dog seizure looks like, the different types of seizures, causes, symptoms, diagnosis, treatment, management, complications, and prevention of canine epilepsy, pet owners can provide the best possible care for their furry friends.
