I have always secured my dogs in the car, but my most recent dog is too small for most safety belts. The apparatus I had previously secured his own harness to the safety buckle, but I was always fearful that in an accident he would still go flying. With the PupSaver, I am no longer worried about this. I installed the PupSaver in my front seat, per the instructions in the video, which was very easy to follow. I wasn't sure how my dog would react to the high back blocking his view, but he just laid his head down on the side facing me and went to sleep. I can drive confident that if something happens on the road, PupSaver will protect my little guy from being flung or thrown. I am incredibly grateful for this product and hope we never have to test it's effectiveness, but I have a feeling if we did, everything would be ok!
