SprayShield Deterrent Spray is a safe, effective way to interrupt dog attacks. It works by surprising and distracting the dog with a powerful citronella spray, giving you time to escape. When sampled on trained attack dogs, SprayShield Deterrent was found to be an equally effective alternative to 10% pepper spray, but with none of the harmful side effects. SprayShield Deterrent is a great safety tool to carry with you to prevent dog attacks, whether you're walking your dog or just jogging around the neighborhood. (Retail Clamshell Package)
