Lead: Approximately 120cm Harness (chest): Approximately 35-40cm I believe it's size S. I've used it a few times, but I'm selling it because the size no longer fits. It has been washed. (This item is used.) Also, as this is a private sale, there may be discrepancies in the color of the images, oversight in the inspection, and errors in the measurements. Please understand this before purchasing. I will answer questions to the best of my ability, so feel free to ask.
