There is little evidence for the ability of dogs to anticipate human seizures. Families of epileptic children were surveyed to investigate seizure-related behaviors in dogs. Approximately 40% of families owned a dog, about 40% of these had seizure-specific behavior, and about 40% of these (approximately 15% overall) showed anticipatory ability. Anticipation occurred early and was both sensitive and specific. Quality of life was higher in families with a dog that responded to seizures.
