One of the easiest harnesses to put on, adjust and remove. Designed to minimize the potential for choking. Features automotive quality buckles, latches and adjusters. The PetBuckle seat belt harness is also designed for use with the versatile PetBuckle Kwik-Connect Tether. The adjustable length tether makes it easier to buckle and allows more freedom of movement for the dog. The tether also provides multiple vehicle attachment points, including the Latch bar system, seat belt and cargo area. The tether’s patented SafeGuard Push-On Connector provides greater ease and convenience. It attaches with just a "push and click" and releases with the push of a button. Just slip the seat belt through the web loop on the harness and buckle up. There are some extremely small and extremely large dogs that will not fit into PetBuckle products.
