The safety harness from Snoozer is the only harness to be crash tested with the same standards of a child safety seat, safe for a 30-pound dog at 30 mph. The unique vest design is made of super strong ballistic nylon that easily fits around your dog's chest. The seat belt latch attaches to seat belt mechanisms and includes adjustable straps allowing for a custom fit to fit almost any pet.
