Epilepsy is the most common neurological disorder in dogs, affecting approximately 1 in 130. Modern antiepileptic drugs and management strategies have transformed quality of life for affected dogs and their owners.
Canine epilepsy causes significant and recurring welfare harm. Seizures are involuntary, unpredictable, and distressing for both dogs and observers. The post-ictal period - which can last hours - involves confusion, anxiety, excessive hunger and thirst, and sometimes aggression. Dogs with poorly controlled epilepsy live with frequent distressing episodes that affect their ability to participate in normal activities. Antiepileptic drugs significantly reduce seizure frequency in most dogs, but side effects including sedation, weight gain, and liver strain require monitoring and management. The welfare of epileptic dogs requires ongoing assessment balancing seizure control against drug burden, with regular quality of life review.
