Car safety is a hot issue, however, pet restraining system manufacturers that have been seeing an increase in sales in the last months may have missed the point, according to a recent study.

According to the news, safety organizations that hope to come up with better ways to keep pets, and owners, safe, have tested most brands of pet restraining systems and the results were not great. According to Center for Pet Safety’s founder, none of the brands of pet harnesses held up in crash simulation tests. Most of the items, the reports show, allowed the dog to become a projectile in the event of a crash. The restraining systems proved to be hazardous not only to pets but also to car occupants while in a crash.
