First Watch AK-1000 Dog Vest - Large

The First Watch AK-1000 Dog Vest in Large is a water safety system engineered to keep working K9s secure during aquatic operations and training scenarios. Designed by First Watch with input from maritime and tactical teams, this large-format vest combines flotation support with a purpose-built suspension system that enables safe rapid extraction of dogs from water environments—critical during water rescue drills, harbor patrol work, and amphibious training exercises.

The AK-1000's construction addresses the biomechanics of canine water safety. The vest supports the dog's torso and chest to maintain head-above-water positioning, while the integrated suspension harness distributes lifting forces across the body rather than concentrating stress on the neck—a critical design principle that prevents tracheal injury during extraction. The harness system adapts to the dog's neck length and torso shape, ensuring stable fit across different Large-size K9s used in law enforcement and military applications. Reflective elements integrated into the design enhance visibility during low-light operations or emergency response scenarios.

This vest is built for handlers who work canines in water-dependent environments—harbor units, water rescue teams, amphibious assault preparation, and tactical training facilities with water obstacles. The Large size fits working dogs in the 60–100 lb range, making it suitable for German Shepherds, Labradors, and comparable service breeds used in law enforcement and military K9 programs. Beyond operational use, the AK-1000 serves recreational purposes for handlers who want verified water safety for their working dogs during off-duty water activities.
