The Martingale design allows you to set a length beyond which collar cannot constrict around pet's neck. When tension is applied collar constricts evenly dispersing the pressure to prevent choking or injury. Durable Nylon material is comfortable in all types of weather. Convenient quick-release for off-lead adventures. Tightens when dog pulls but loosens up for a comfortable and not too tight fit. Great for training and everyday activities.
