Rogz XX-Large Collar - Ideal for MegaDogz (Great Danes, BullDog etc) Few frills, no fuss. Just great quality and reflective touch. Rogz Highly Reflective Utility Range is both the black tie and the 4x4 of the Rogz range. Timeless and classic, hardy but cool. Never shaken - or stirred. Straight-forward and durable with ultimate night time visibility. All joins are box stitched for extra strength and a quality finish. Note that this range needs to be turned inside out when operating in stealth mode as the reflective stitching is found on one side. Lively colors with reflective stitching and quality build will give long lasting satisfaction.
