Canine Friendly Safety Harness Why Buckle Up Your Pup? Seat belts save lives. Even low speed collisions can lead to fatalities, as unrestrained pets can be launched into dashboards or windshields injuring you, your passenger and your dog. How It Works Harness Features How is the Canine Friendly Dog Safety Harness Different? Crash testing the Safety Harness as a whole functioning unit under life-like simulations better predicts how the product will perform in the real world. Canine Friendly has gone beyond component durability testing by subjecting the Dog Safety Harness to independent testing by MGA Research, an industry-leading auto testing facility located near Detroit, Michigan. Crash tests using weighted mannequins and auto-sled simulation performed by MGA concluded that the Canine Friendly Safety Harness exceeds industry's Pet Safety - Durability Test standards for dogs up to 85 lbs. Crash test certified up to 85 lbs at 30 mph. The heavy duty quality of the Safety Harness is a result of using high-grade 1050D nylon fleeced lined chest panel (Image 1), high break strength aluminum buckles (Image 2), stainless steel O-Rings with 2,300 to 5,000 lb break strength webbing (Image 4), 2,200 to 2,300 break strength stainless steel slides (Image 3) and seat belt-rated thread that are all tested to be highly effective for its purpose.
