A flexible reflective flat retractable pet leash is retained within a retractable housing device. The reflective pet leash reflects incoming light beams back in the same direction as emanated. The reflected light beam provides accurate illumination of the pet leash and the location of the pet during dusk or nighttime hours. This retractable pet leash is created by weaving or integrating reflective material fabric/tape within a flat leash portion. The reflective retractable pet leash is composed of a flat leash portion operable to sustain substantial tensile forces having a front and back side. Reflective means are integrated within the flat leash portion being operable to provide reflectivity. A retractable housing device having a handle portion, a retraction control member actuated by a retraction control switch, a housing body with an internal chamber appointed with a reel member, and an extension-retraction aperture is provided for housing the leash.
