Understanding Seizures in Old Dogs

Seizures stem from abnormal electrical activity in the brain and can be particularly concerning when they occur in older dogs.
Causes and Risk Factors
One of the primary causes of seizures in dogs is idiopathic epilepsy, although it’s less commonly diagnosed in older dogs, typically presenting between 2-6 years of age. In senior dogs, seizures often have underlying causes such as brain tumors, liver disease, kidney failure, or other metabolic conditions. Several factors can increase the risk of seizures, including:
- Genetic predisposition: Some dog breeds are more prone to seizures.
- Age-related diseases: Conditions like cerebrovascular disease can provoke seizures.
- Toxins: Exposure to toxins can lead to neurological disruptions.
Types of Seizures Experienced by Older Dogs
Older dogs can experience different types of seizures, including:
- Generalized seizures (grand mal): Involves the entire body, typically characterized by muscle rigidity, loss of consciousness, and convulsions.
- Focal seizures: Affect only part of the brain and may cause unusual movements in one limb or one side of the body.
- Psychomotor seizures: Can cause strange behavior, such as frantic barking or snapping at the air as if catching flies.
Stages of Seizures
Seizures in dogs typically proceed through three stages:
- Aura: Indicative signs such as restlessness or anxiety.
- Ictal phase: The active seizure period which includes involuntary movements, drooling, and loss of consciousness.
- Postictal phase: A period of disorientation and confusion following the seizure, which can last from minutes to days.
Recognizing Seizure Symptoms

When an older dog experiences a seizure, certain physical and behavioral symptoms are evident. Understanding these signs can prepare an owner to respond appropriately.
Common Symptoms
- Loss of Consciousness: A dog may collapse and become unresponsive.
- Convulsions: Involuntary jerking or twitching movements are common during seizures.
- Twitching: Minor localized twitches, especially in the face or limbs, may occur.
- Fitting: The dog might display spasms with rhythmic, jerking muscle contractions.
- Fainting: Brief episodes of unresponsiveness like fainting can precede or be part of a seizure.
Behavioral Changes
- Shaking: Dogs may shake uncontrollably during the pre-ictal or ictal phase of a seizure.
- Abnormal Behavior: Dogs might show unusual behaviors, such as staring into space, appearing confused, or showing anxiousness before a seizure begins.
Diagnosing Seizures in Senior Dogs

When a senior dog exhibits seizure activity, accurate diagnosis is pivotal. Veterinarians rely on a combination of thorough assessments and specific diagnostic tests to determine the underlying cause of seizures in older dogs.
Veterinary Assessment
A veterinarian will first conduct a comprehensive assessment of the dog’s history, including the frequency, duration, and nature of the seizures. This history is critical because it helps the veterinarian differentiate between true seizures and other conditions that might mimic seizures. Observations from the owner can be instrumental in this initial evaluation phase.
The veterinarian will also perform a physical examination to assess the dog’s overall health and neurological status. They will look for any abnormalities or signs of systemic disease that could be contributing to the seizure activity.
Diagnostic Tests
Following the assessment, a veterinarian may recommend a suite of diagnostic tests to identify the cause of the seizures. This typically includes:
- Bloodwork: A complete blood count (CBC) and chemistry panel provide valuable information about organ function, electrolyte balance, and can indicate the presence of infections or inflammation.
- Urinalysis: Analyzing the urine helps in checking for urinary tract infections, kidney function, and other metabolic conditions.
- Advanced Imaging:
- Magnetic Resonance Imaging (MRI): Offers detailed images of the brain’s structure to rule out tumors, strokes, or structural abnormalities.
- Computed Tomography (CT) scans: Useful for detecting lesions or anomalies within the brain.
Combining a veterinarian’s expertise with these diagnostic tools ensures a more precise understanding of the seizures, allowing for targeted treatment plans tailored to the individual needs of the senior dog.
Common Health Conditions Related to Seizures

Seizures in older dogs may stem from various health conditions, primarily involving metabolic diseases or neurological disorders. These underlying conditions disrupt normal brain function, causing the episodes that pet owners witness as seizures.
Metabolic Diseases
Metabolic diseases pertain to the dysfunctions in the processing of the body’s essential biochemical reactions. Two common metabolic diseases leading to seizures are:
- Liver Disease: The liver filters toxins from the blood and manages various metabolic processes. When the liver fails to function properly, as in liver disease, it can lead to a buildup of toxins in the bloodstream, which may cause seizures.
- Kidney Disease: Healthy kidneys are vital for maintaining balanced electrolyte levels and removing waste products from the bloodstream. Kidney disease can result in the accumulation of waste and unbalanced electrolytes, potentially leading to seizures.
- Diabetes: An imbalance in blood sugar levels, especially in the case of low or high blood sugar, can induce seizures as the brain requires a constant supply of glucose to function correctly.
Neurological Disorders
Neurological disorders are conditions that affect the brain, spinal cord, or nerves. The following are notable neurological conditions that can be associated with seizures in geriatric canines:
- Brain Tumors: The presence of a brain tumor can cause abnormal electrical activity in the brain, resulting in seizures. Brain tumors may be primary, originating in the brain, or secondary as a result of cancer spreading from another location.
- Strokes: A stroke occurs when the blood supply to the brain is interrupted, causing brain damage. Depending on the stroke’s severity and location, it can lead to seizures.
- Encephalitis: This denotes inflammation of the brain, often caused by infectious agents that may result in seizure activity.
Proper diagnosis and management of the underlying condition are critical in the treatment and control of seizures in older dogs.
Treatment Options for Seizure Management

Effective seizure management in older dogs hinges on a combination of appropriate medications and supplements, along with tailored diet and lifestyle changes. These strategies work in tandem to reduce seizure frequency and severity, while aiming to preserve a high quality of life for the canine.
Medications and Supplements
Anti-seizure Medication: A veterinarian may prescribe anti-seizure medications to control seizure activity. Common choices include:
- Phenobarbital: Widely used, can require periodic blood monitoring.
