(Legal) Use of Trained Dogs
Trained dogs’ sniffing of cars and lockers does not constitute a search under the Fourth Amendment. The alert of a trained dog to a locker or car provides reasonable cause for a search of the locker or car if the dog is reasonably reliable in indicating that contraband is currently present. A district need not show that the dog is infallible or even that it is reliable enough to give probable cause.
Trained dogs’ sniffing of students does constitute a search and requires individualized reasonable suspicion.
