The Guard Dog is a portable door guard equipped with a siren alarm. When the Guard Dog is activated with the motion sensitivity switch, a 120+ decibel siren sounds if the door or door handle is moved. The Guard Dog is ideal for keeping you and your loved ones safe from harm. Its folding, shock-corded design snaps together in seconds and works on most door handle styles. It comes with leg extenders, allowing the guard dog to fit any sized door. It is equipped with a steel leg preventing the door from opening, and has a non-skid foot that grips any floor surface. The Guard Dog folds to a compact 12" x 5" size making it portable so you can take it with you when you travel. The Guard Dog is ideal for anyone and can be used virtually anywhere.
