Epilepsy is the most common neurological disorder in dogs, causing recurrent seizures that are frightening and potentially harmful — but most cases can be well-managed with medication.
Epilepsy causes intermittent, acute welfare harm through the seizure events themselves — which involve loss of consciousness, uncontrolled muscle activity, and a post-ictal period of confusion and fear that can last hours. Between seizures, poorly controlled epileptic dogs may live in a state of continuous medication side effects including sedation, ataxia, or polyphagia. The welfare burden falls not just during seizures but in the cumulative effect of chronic neurological disease. Good welfare requires accurate diagnosis, appropriate medication selection, regular monitoring, and willingness to pursue second-line therapies in refractory cases rather than accepting poor control.
