Understanding Canine Seizures
Seizures in dogs can be a distressing experience for both the dog and their owner. It is important to understand the causes and types of seizures in order to provide appropriate care and treatment.
Causes of Seizures in Dogs
Seizures in dogs can be caused by various factors, including epilepsy, brain tumors, infections, toxins, and metabolic issues. Identifying the underlying cause of seizures is crucial for appropriate treatment (Tufts University – Clinical Nutrition). Some common causes of seizures in dogs include:
-
Toxins: Certain plants like Brunfelsia (Yesterday-Today-and-Tomorrow) and Sago palm, as well as foods like Xylitol, Caffeine, and Dark chocolate, can lead to seizures in dogs if ingested. Additionally, rodenticides, insecticides, and illicit drugs can also trigger seizures.
-
Metabolic Issues: Liver disease, kidney failure, and imbalances in blood sugar or electrolytes can contribute to the occurrence of seizures in dogs (VCA Canada).
-
Idiopathic Epilepsy: Idiopathic epilepsy is the most common cause of seizures in dogs. It is an inherited disorder with an unknown exact cause. Dogs with idiopathic epilepsy experience recurring seizures without any underlying structural brain abnormalities.
Types of Seizures in Dogs
Seizures in dogs can manifest in different ways, and understanding the types of seizures can help in their diagnosis and management. Common types of seizures in dogs include:
-
Generalized Seizures: Generalized seizures involve the entire body and can be characterized by convulsions, loss of consciousness, muscle stiffness, and jerking movements.
-
Focal Seizures: Focal seizures, also known as partial seizures, originate in a specific area of the brain. They can cause localized twitching or abnormal movements in one part of the body.
-
Cluster Seizures: Cluster seizures refer to multiple seizures occurring within a short period of time, often with brief periods of recovery in between.
-
Status Epilepticus: Status epilepticus is a medical emergency characterized by prolonged seizures or seizures occurring in rapid succession. It requires immediate veterinary attention.
Identifying the type of seizure your dog is experiencing can aid in determining the most appropriate treatment approach and management plan. If you observe any signs of epilepsy in your dog, such as recurring seizures, it is important to consult with your veterinarian for a proper diagnosis and guidance on the best course of action.

Identifying Seizure Triggers
When it comes to understanding and managing seizures in dogs, it’s important to identify the triggers that can lead to these episodes. By pinpointing the underlying causes, dog owners and veterinarians can work together to develop an effective treatment plan. In this section, we will explore two common seizure triggers: toxins and medications.
Toxins as Seizure Causes
Toxins are a common cause of seizures in dogs, and identifying the source of sudden seizures in previously healthy dogs may require a neurology or internal medicine work-up. The ASPCA Animal Poison Control Center highlights that many seizures can be linked to toxin exposure (ASPCApro).
There are several substances that can potentially trigger seizures in dogs if ingested or exposed to in large amounts. These include certain plants like Brunfelsia (Yesterday-Today-and-Tomorrow) and Sago palm, as well as foods like Xylitol, Caffeine, and Dark chocolate. It’s important to keep these items out of your dog’s reach to prevent accidental ingestion.
Additionally, some chemical products used in homes and gardens can pose a seizure risk to dogs. Rodenticides and insecticides such as Metaldehyde, Bifenthrin, Strychnine, and Zinc phosphide are potential causes of seizures in dogs. It’s crucial to follow proper storage and usage guidelines when handling these substances to minimize the risk to your furry friend.
Illicit drugs like Cocaine, Amphetamines, Cannabis, and Synthetic cannabinoids, as well as other substances like Ethylene glycol, Mycotoxins, and Bee sting envenomation, can also trigger seizures in dogs. It’s important to be aware of your dog’s surroundings and prevent access to these potentially harmful substances.
Medications and Seizures
In some cases, certain medications can lead to seizures in dogs. Medications such as Fluorouracil (5-FU) cream, Ivermectin, Fluoroquinolone antibiotics, and Ibuprofen have the potential to cause seizures when ingested in overdose situations or administered incorrectly.
It’s crucial to follow the recommended dosage and administration guidelines provided by your veterinarian when giving medications to your dog. If you suspect that your dog may have ingested an incorrect dose or is experiencing adverse effects from a medication, it’s important to seek immediate veterinary attention.
Identifying and avoiding seizure triggers is an essential part of managing seizures in dogs. By being vigilant about potential toxins and ensuring proper medication administration, you can help reduce the frequency and severity of seizures in your furry companion. If you suspect that your dog is experiencing seizures, it’s important to consult with a veterinarian for a thorough evaluation and guidance on further steps to ensure your dog’s well-being.

Canine Epilepsy
Epilepsy is a common neurologic disorder that affects both humans and dogs. In this section, we will explore the genetic factors associated with epilepsy in dogs and the treatment options available for dogs with this condition.
Genetic Factors in Epilepsy
Genetics play a significant role in the development of epilepsy in dogs. Certain breeds are predisposed to this condition, indicating a genetic component in the development of seizures. It is believed that specific genes or combinations of genes contribute to an increased susceptibility to seizures.
While the exact genetic causes of epilepsy in dogs are still being researched, it is important to note that not all cases of epilepsy can be attributed to genetic factors alone. Other environmental and physiological factors may also contribute to the development of seizures in dogs.
Treatment Options for Epileptic Dogs
When it comes to treating epilepsy in dogs, there are various approaches that can be considered. The primary goal of treatment is to minimize the frequency and severity of seizures, improving the quality of life for the affected dog.
-
Medication: Antiepileptic drugs (AEDs) are commonly prescribed to manage seizures in dogs. These medications work by stabilizing the electrical activity in the brain and reducing the occurrence of seizures. However, it is important to note that not all dogs respond consistently to medication or may experience severe side effects (NCBI). In some cases, the epilepsy may be refractory, meaning it does not respond well to medication.
-
Dietary Approaches: In recent years, dietary therapy has shown promise as an adjunct treatment for epilepsy in dogs. One such approach is the ketogenic diet, which is high in fat, low in carbohydrates, and moderate in protein. The ketogenic diet has been used for decades to manage seizures in humans and has shown effectiveness in both children and adults (NCBI). Studies have also shown that feeding dogs a proprietary ketogenic diet can significantly reduce seizure frequency, with some dogs experiencing a complete cessation of seizures. Additionally, dietary changes have been reported to decrease seizure frequency and severity, as well as protect against potential side effects of antiepileptic drugs (NCBI).
Treatment for epileptic dogs should always be conducted under the guidance of a veterinarian. They will be able to assess the severity of the seizures, evaluate the dog’s overall health, and recommend the most appropriate treatment options. Regular follow-up visits are essential to monitor the dog’s response to treatment and make any necessary adjustments.
Understanding the genetic factors associated with epilepsy in dogs and exploring treatment options such as medication and dietary approaches can help dog owners make informed decisions to manage and improve the quality of life for their epileptic pets.
Dietary Approaches for Seizures
When it comes to managing seizures in dogs, dietary approaches can play a significant role in reducing seizure frequency and improving overall well-being. Two notable dietary strategies include the ketogenic diet for dogs and the impact of diet changes on seizures.
Ketogenic Diet for Dogs
The ketogenic diet, a high-fat, low-carbohydrate, and moderate-protein protocol, has shown effectiveness in stopping seizures in both children and adults, including those that are resistant to medications. This diet has also been explored as a potential treatment option for dogs with epilepsy.
The ketogenic diet for dogs involves feeding them a carefully formulated diet that is rich in healthy fats and limited in carbohydrates. By restricting carbohydrates, the body is forced to utilize fats as its primary source of energy, resulting in the production of ketones. Ketones have been shown to have anticonvulsant properties, which can help reduce seizure frequency.
A study conducted on dogs fed a proprietary ketogenic MCT (medium-chain triglycerides) diet for 3 months found a significant reduction in seizures. Some dogs experienced a 100% reduction in seizure frequency, while others showed at least a 50% decrease in seizures (NCBI). This study highlights the potential effectiveness of the ketogenic diet for managing seizures in dogs.
Impact of Diet Changes on Seizures
Dietary changes can have a notable impact on seizure frequency in dogs. An investigative study found that 67.7% of owners whose dogs were diagnosed with intractable epilepsy reported changing their dogs’ diet after diagnosis. These dietary changes resulted in reported decreases in seizure frequency (88.2%), seizure severity (61.8%), and protection against potential side effects of antiepileptic drugs (62.5%).
Homemade diets have also shown promise in reducing seizure frequency and allowing for a complete cessation of seizures for extended periods. This highlights the importance of diet-based metabolic therapy as a treatment option for seizures in dogs (NCBI).
When considering dietary changes, it’s essential to work closely with a veterinarian or a veterinary nutritionist to ensure that the diet is properly balanced and meets your dog’s nutritional needs. They can guide you in formulating an appropriate diet that suits your dog’s specific condition and requirements.
It’s important to note that while dietary approaches can be beneficial, they may not be effective for all dogs with seizures. Each dog is unique, and what works for one may not work for another. Therefore, it’s crucial to consult with a professional to determine the most appropriate dietary approach for your dog’s specific situation.
Managing seizures in dogs requires a comprehensive approach, and dietary strategies can be an important component of that approach. By considering the ketogenic diet and the impact of diet changes on seizures, you can potentially help improve your dog’s quality of life and reduce the frequency of seizures.
Managing Seizures in Dogs
When it comes to managing seizures in dogs, two important aspects to consider are the diagnosis and testing process, as well as the medication used for seizure control.
Diagnosis and Testing
After a dog experiences a seizure, a thorough diagnostic process is essential to determine the underlying cause and develop an appropriate treatment plan. This typically involves a combination of a comprehensive history, physical examination, and various tests. According to VCA Canada, the diagnostic process may include:
- History: Gathering information about the dog’s medical history, previous seizure episodes, and any potential triggers.
- Physical Examination: A thorough examination of the dog’s overall health, including neurological assessments.
- Blood and Urine Tests: These tests help identify any underlying metabolic or organ abnormalities that may contribute to seizures.
- Electrocardiogram (ECG): An ECG may be recommended to assess the heart’s electrical activity and rule out any cardiac-related causes of seizures.
- Additional Diagnostics: In some cases, further diagnostic tests such as CT scans, MRI, or cerebrospinal fluid (CSF) sampling may be necessary to evaluate the severity and frequency of seizures.
The specific diagnostic approach may vary depending on the individual dog’s condition and the severity of the seizures. By conducting these tests, veterinarians can gain valuable insights into the potential causes of the seizures and develop an appropriate treatment plan.
Medication for Seizure Control
Once a diagnosis is made, medication is often prescribed to help control and manage seizures in dogs. The two most commonly used medications for seizure control in dogs are phenobarbital and potassium bromide (VCA Canada). These anticonvulsant medications work by reducing the hyperexcitability of brain cells, thereby reducing the frequency and intensity of seizures.
Other anticonvulsants, such as zonisamide (Zonegran®) and levetiracetam (Keppra®), may also be used, especially for dogs that do not respond well to standard treatments. In some cases, combination therapy involving multiple anticonvulsant medications may be required to effectively manage seizures.
It’s important to note that anticonvulsant medication for dogs with seizures is typically a lifelong treatment. Abrupt discontinuation of medication can lead to more severe seizures in the future. Close monitoring by a veterinarian is necessary to adjust medication dosages, if needed, and ensure optimal seizure control.
In certain situations, such as status epilepticus, which is characterized by a seizure lasting more than five minutes, immediate veterinary treatment is crucial to prevent life-threatening complications. In such cases, intravenous anticonvulsants are administered to stop the seizure and stabilize the dog’s condition.
By diagnosing seizures accurately and implementing appropriate medication for seizure control, veterinarians can help improve the quality of life for dogs with epilepsy. Regular follow-up visits and adjustments to the treatment plan may be necessary to optimize seizure management and minimize potential risks.

Challenges in Seizure Treatment
While many dogs with seizures can be effectively managed with medication and lifestyle changes, there are cases where treatment becomes more challenging. In this section, we will explore two specific challenges that can arise in the treatment of seizures in dogs: refractory epilepsy and multi-drug therapy approaches.
Refractory Epilepsy in Dogs
Refractory epilepsy refers to cases where dogs do not respond consistently to medication(s) or experience severe and unacceptable side effects, leading to medication-resistant seizures. Approximately 30-40% of dogs with epilepsy are diagnosed with refractory epilepsy. Despite receiving appropriate anti-epileptic drugs, these dogs continue to experience seizures or have insufficient seizure control.
The exact reasons why some dogs develop refractory epilepsy are not fully understood. It could be due to individual variations in drug metabolism, the underlying cause of epilepsy, or other factors. Managing refractory epilepsy requires a tailored approach, and veterinarians may need to explore alternative therapies or adjust the treatment plan to find the most effective strategy for each individual dog.
Multi-Drug Therapy Approaches
In cases of refractory epilepsy, multi-drug therapy may be necessary. This approach involves using two or more anti-epileptic drugs in combination to enhance seizure control. Additional drugs such as gabapentin, zonisamide, levetiracetam, or pregabalin may be added to the treatment regimen.
The goal of multi-drug therapy is to improve seizure management by targeting different mechanisms of seizure activity. Combining medications with complementary modes of action can enhance their overall effectiveness. However, it’s important to note that multi-drug therapy can present challenges in terms of dosing, potential drug interactions, and monitoring for side effects.
When using multi-drug therapy, close collaboration between the veterinarian and the dog owner is crucial. Regular follow-up appointments and monitoring of the dog’s response to treatment are necessary to ensure that the medication regimen is appropriately adjusted.
It’s important to remember that refractory epilepsy and multi-drug therapy are more complex aspects of seizure treatment in dogs. If your dog is diagnosed with epilepsy or shows signs of seizures, it is essential to work closely with a veterinarian who can provide proper guidance and develop an individualized treatment plan based on your dog’s specific needs.
Understanding the challenges associated with seizure treatment helps dog owners and veterinarians navigate the complexities of managing epilepsy in dogs effectively. By staying informed and working collaboratively, we can strive to provide the best possible care for our furry companions living with this condition.
