  • Patent number: 5732415
    Abstract: The present invention is an eye protection device adapted to be worn by a canine. The device comprises an eye enclosure element such as a transparent plastic goggle which is adapted to rest snugly against the face of a canine. A pair of side straps extend from opposing sides of the eye enclosure element to connect to a collar adapted to be worn about the neck of the canine. The side straps are length adjustable as by hook and loop attachments, snaps or pawl mechanism and couple to the collar along a selected length of the collar thereby allowing two-dimensional adjustment of the side straps. A preferred embodiment of the invention further includes a pivot element for easily rotating the eye enclosure element away from the eyes of the canine when the invention is not needed. Alternately, the invention can include anti-lift and anti-loss straps for maintaining use of the invention when the wearing animal is using the invention in inclement conditions.
