This complete car safety system, specially designed for dogs, features a unique two-in-one design: a buckle that securely attaches to the car seat's headrest and a shock-absorbing safety belt, providing a comfortable ride for your dog. The total length of the safety belt is adjustable between 72 and 84 cm, and its width is 2.5 cm, suitable for most dog sizes. Made from durable nylon with woven-in reflective strips, the reflective strips ensure enhanced visibility at night, while the elastic part absorbs shocks during sudden braking or unexpected movements, preventing injuries to your dog. The headrest buckle features a quick-release red button, allowing for easy attachment or detachment in seconds without tools. A robust metal carabiner at the bottom of the safety belt securely attaches to your dog's collar or harness. Adjustable buckles allow for easy adjustment of the safety belt's length, creating a comfortable and secure space for your dog. Unlike regular car seat belts, this safety belt connects directly to the headrest, without occupying the original seat belt opening, making it convenient for passengers. Your dog can sit or lie comfortably in the back seat, but will not be able to jump forward, lean out the window, or distract the driver. Robust metal components and thick nylon webbing ensure its long lifespan and high tensile strength. Even when covered in mud or hair, the system is easy to remove and wipe clean with a damp cloth. It is an essential accessory for safe travels with your dog to walks, the vet, or your holiday destination.
