Auburn Leathercrafters' Cotton Rope with Leather Dog Collars are strong, soft, and comfortable. We use US grown and produced cotton rope and genuine Wickett & Craig chestnut bridle leather and a solid brass buckle and dee-ring. All of this makes this collar not only functional and comfortable, but one that you will be happy to use. The natural cotton rope is approximately 1/2" in diameter: a nice size for a medium to large dog. Super soft for those with sensitive necks. Auburn Leathercrafters Natural Cotton and Leather Rope Leashes are a perfect match. Proudly Made in the USA!
