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 ?Lupine Guarantee? to see how EZ it is! Lupine High Lights are made from nylon with reflective threads woven into the front, back and edges for maximum visibility. The reflective threads bounce light back to an observer so that these products may be seen in low-light or dark conditions when light shines on them. Made with strong bar-tack stitching, welded steel hardware, and ends which are turned under and stitched to protect fur and skin. Matching collars and harnesses are available. High Lights are available in 6 bright colors and three widths: 1/2", 3/4" and 1". The 1/2"-wide leashes are suitable for small dogs and puppies under 20 pounds. These leashes are available in two lengths: 4-foot or 6-foot. Shorter leashes keep the dog closer. Consider the distance from your hand to the dog?s collar when choosing a length. A leash can always be shortened by holding it closer to the dog. 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.
