The harness is designed with a focus on comfort for the dog and does not restrict the dog's range of movement. It is easy to get on and off as it does not have to go over the dog's head. The harness has a reflective edge, as well as reflectors on the shoulders, which ensures that the dog is visible during evening walks. The harness is adjustable - it can be tightened and loosened to achieve the best fit for your dog.
