Additional Details ------------------------------ Product description: Lupine products are proudly built in Conway, New Hampshire and Guaranteed (Even if Chewed). They are not chew-proof (no fabric is!) but if they get chewed, LupinePet will replace them. Search on OLupine GuaranteeO to see how EZ it is! The Lupine Adjustable Step In harness is sized by the inches-around the dog's ribcage. To choose the correct size always measure around the body, just behind the front legs. Measure snugly, and then add an extra 5% to find the actual adjusted size of the harness girth. Or, measure the length of the girth strap from the dogOs current harness. This harness goes on from the feet up. Start by unbuckling the clip, then place each front paw on either side of the center strap. Then bring the two parts up and over the dogOs back and clip the girth strap closed. Adjust the three straps as needed. The harness should be removed from the dog when the leash comes off and it should not be left on an unattended dog. Lupine Originals are made from woven nylon in an array of colorful designs. The pattern is woven into the webbing, rather than printed or sewn on. Made with strong bar-tack stitching, welded steel hardware, and ends are turned under and stitched to protect fur and skin. Matching collars and padded handle leashes are available. Machine or hand-wash, warm water and mild soap (no bleach or bleach alternative). Air dry completely before use. Lupine products are not intended for tie-out. Directions: Lupine Adjustable Step In harness is sized by the inches-around the dog's ribcage.
