I'm selling this because I bought it but never used it. Leash: 120 cm Harness (neck): Adjustable from approximately 25 to 40 cm Harness (chest): Adjustable from approximately 30 to 50 cm It has a cute pouch on the back! The harness also has a belt around the chest, so it doesn't put all the pressure on the neck, making it gentle on your dog.
