This German leather dog collar is made from one of the world's most exquisite leathers - elk. It's supremely soft and supple, making it one of the most comfortable dog collars a dog can wear. The leather dog collar has a rounded single-stranded nylon core that makes it incredibly strong. The Elk leather is then rolled and sewn, and finished with a nickel-plated buckle and lead loop. Especially useful for long-haired dogs, these leather dog collars are extremely gentle on the fur.
