Epilepsy affects approximately 0.6-0.75% of dogs and causes significant welfare compromise. Effective management significantly reduces seizure frequency and improves quality of life.
Epilepsy causes episodic welfare harm — seizures produce loss of consciousness, involuntary movements, and a postictal phase of disorientation, blindness, and anxiety that can last hours. Dogs experiencing cluster seizures or status epilepticus face risk of life-threatening hyperthermia and brain injury. Between seizures, well-controlled epileptic dogs can have excellent quality of life; it is the uncontrolled or inadequately managed cases that suffer most. Starting anti-epileptic medication early and titrating to effect is the welfare-optimal approach. Common first-line medications (phenobarbital, potassium bromide, levetiracetam) are effective in the majority of dogs when dosed appropriately and monitored for toxicity. Owner education about recognizing cluster seizures and having emergency diazepam available for home administration reduces emergency hospital visits and welfare harm from uncontrolled seizure activity. Regular drug level monitoring optimizes control while minimizing side effects.
