Create a loop by shortening the 56cm total length by 3cm and try fitting it over your dog's head. This will give you an idea of how the 56cm chain will look when worn. - Brand: Herm. Sprenger - Material: Curogan - Country of Origin: Germany I used this for a few months when my Great Dane was a puppy, but they quickly outgrew it, so it wasn't used much. Due to the nature of Curogan (copper), the color has changed from the original rose gold. I have marked it as "slightly dirty" but please understand that it is not actually dirty. Thank you for looking.
