Epilepsy affects approximately 1-2% of dogs and causes significant acute welfare harm during seizures and potential chronic welfare impacts from anticonvulsant medications and interictal anxiety.
Epilepsy welfare encompasses multiple dimensions: the acute suffering of seizures themselves (loss of consciousness, muscle spasm, post-ictal disorientation), the anticipatory anxiety that may develop in dogs who experience clusters, and the chronic effects of anticonvulsant medications (sedation, polyphagia, hepatotoxicity from phenobarbital). Dogs with poorly controlled epilepsy face repeated acute welfare events that accumulate over years. Medication management involves balancing seizure control against drug side effects - phenobarbital reduces seizure frequency but causes hepatotoxicity in some dogs requiring regular liver monitoring. Welfare-centered epilepsy management uses validated seizure diaries, regular drug level monitoring, and honest quality-of-life assessment.
