ABSTRACT:
An improved aerodynamic disc comprised of a disc shaped center, a circumferential rim portion, and a protrusion extending from one surface of the disc shaped center. The protrusion extends beyond the circumferential rim portion to provide a resting support surface. This resting support surface when combined with the resting support surface of the circumferential rim portion in contact with the landing surface provides an opposing elevated rim portion which is designed to aid a pet or a person to retrieve the aerodynamic disc from the landing surface. The protrusion may be permanently affixed or removable and attachment members such as including a whistle element or a light element may be attached to the center shaped disc in addition to the protrusion.
