Epileptic seizures are a complex and worrisome condition that can affect four-legged friends – as well as us two-legged friends. These seizures can vary in intensity and type depending on which part of the brain is affected. It is important for you as an owner to understand the different aspects of epilepsy in dogs – including causes, symptoms and how it is treated.

What is epilepsy?
Epilepsy in dogs is a collective term for various types of seizures caused by abnormal electrical activity in the brain. The dog may have sudden, uncontrolled seizures with or without loss of consciousness.
Epileptic seizures can be divided into two main categories:
Focal og generalized seizuresThe type of seizure a dog experiences depends on the extent of the brain damage.
Focal seizures:
These seizures affect only one part of the dog's body. Symptoms may be limited to a specific body part – and the dog may experience involuntary movements or changes in behavior in that part of the body.
Generalized seizures:
Here, the seizure affects the entire body. The dog's symptoms are more extensive – and they may experience stiffness, twitching or convulsions throughout their body. This may also involve loss of consciousness and other dramatic symptoms.
Symptoms and behavioral changes in epilepsy in dogs
In some dogs, changes in behavior may be noticed before a seizure occurs. For example, they may become more contact-seeking and restless. During the seizure itself, the dog will usually show episodic – involuntary movements or behavior that often lead to stiffness, twitching or convulsions. It is not uncommon for the dog to drool, urinate or defecate during a seizure. After the seizure, the dog may appear restless, confused or even aggressive.
When should I contact a vet?
If your dog experiences a seizure – it is important to contact a veterinarian immediately. If the seizure lasts more than 5 minutes – you should see a veterinarian immediately. In addition, you should go directly to the veterinarian if your dog experiences multiple seizures in the same day.

Different types of epilepsy in dogs
Epilepsy can have different causes – and it is important to understand the different types:
Idiopathic epilepsy:
This is a term for epileptic seizures in dogs with a known genetic predisposition to the condition. Idiopathic epilepsy is the most common cause of epileptic seizures in dogs – and is often linked to genetic factors.
Structural epilepsy:
Structural epilepsy is the term for seizures that occur as a result of proven or suspected structural changes in the brain. Causes can include brain tumors or previous head injuries.
Unknown cause:
Some seizures have no identified cause – and are not associated with structural damage to the brain.
Diagnosis and treatment of dogs with epilepsy
Idiopathic epilepsy is a diagnosis of exclusion – meaning that the diagnosis is made by ruling out other possible causes of seizures. The veterinarian will perform a thorough clinical and neurological examination including blood and urine tests. Further diagnostic tests such as X-rays, ultrasound, CT, MRI and spinal fluid tests may also be necessary to get a complete picture of your dog’s condition.
Treatment for epilepsy varies depending on the frequency and severity of seizures. If your dog is experiencing frequent seizures, cluster seizures, or prolonged seizures, treatment will be considered. The goal of treatment is to reduce the number of seizures and their duration. Treatment does not mean that your dog will never have another seizure.
There are various medications available for the treatment of epilepsy in dogs. Some common medications include phenobarbital, imepitoin, potassium bromide, and levetiracetam. It is important to understand that not all dogs respond well to medication – and side effects can occur. It is important that the dosage of medication is adjusted as needed and that the course of treatment is planned in consultation between the owner and veterinarian.
Summary
Epilepsy is a complex condition – and how dogs are affected varies from person to person. Understanding the disease by learning about the different types of seizures, causes, diagnostic methods and treatment options is important for you as a dog owner. Working closely with an experienced veterinarian will help provide the best possible care for dogs suffering from epilepsy and ensure they receive the treatment they need to live a good life.
