Check out the crash test video of the only dog car safety harness to be crash tested – The Pet Buckle®. I would like to caution you before watching the video. Although the video is of crash test dog dummies, they closely resemble dogs. Visit http://www.immioutdoors.com/petbuckle/sledtest.htm to watch the video.
