Eco by Lupine products are proudly built in Conway, New Hampshire and Guaranteed (Even if Chewed, See Lupine Brand website for details). Made from recycled plastic bottles. Bottles are melted, purified and extruded into thread. The thread is then woven to create this unique soft yet strong material with a rich texture. 1-Inch wide harnesses are suitable for medium and larger dogs. Features strong bar-tack stitching, welded D-rings and a custom designed side-release buckle. In 9 designer colors with matching leashes and collars available. To determine harness size, measure snugly around the dog, just behind the front legs, then add an extra 5-Percent for a comfortable fit. Machine wash, warm water, mild soap (no bleach or bleach alternative). Air dry. Lupine products are not recommended for tie-out.
