A pet leash includes an elongated shaft formed of an inner core of bendable but extremely resilient tubing similar to that used to construct certain tent frames. The tubing is encapsulated by a cylindrical foam layer and an outer hollow sleeve that minimize impact with surrounding objects when the shaft is flexed and suddenly released. At an upper end of the shaft is a handle formed of a length-adjustable strap with a loop attached thereto. A clip at the lower end of the shaft is releasably securable to either a pet collar or an adjustable yoke. The resilient-but-flexible shaft easily bends around trees and similar obstructions but returns to an original, linear configuration when a stressing force is removed to prevent entangling.
