Eight mixed-breed canines with naturally occurring epilepsy were implanted with a mobile iEEG recording device and monitored continuously for multiple months. Four dogs had an inadequate number of seizures for algorithm training and testing. Lead seizures are defined as seizures separated by a minimum of 4 hours. Dogs with fewer than 5 lead seizures (italicized) were excluded from analysis. Dog 1 (Buck) died after approximately a year of iEEG monitoring.
