I purchased this on the spur of the moment while traveling on October 5, 2025, but it's a different type than usual, and my dog didn't like it, so I couldn't even put it on. It's as good as new. Lightweight harness for medium-sized dogs, designed to reduce strain on the neck. - Model Name: Sport EX - Size: M - Suitable Weight: Up to 20kg - Neck Size: 36cm - 51cm - Chest Size: 43cm - 63cm Reflective for safety at night.
