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 '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 leashes and harnesses are available. High Lights are available in 6 bright colors and three widths: 1/2", 3/4" and 1". These 3/4" wide collars are available in three adjustable size ranges: 9-14 inches; 13-22 inches; 15-25 inches. To determine correct collar size, measure snugly around the middle of the dog's neck, then add an extra 5-percent for a comfortable fit. Or, measure the current collar. 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.
