Dog Master Bark Stop
Stop nuisance barking or prevent unwanted behaviors from your dog or cat safely and easily. This handheld unit blasts out a bark-stopping sound to stop dogs up to 50 feet away. High-decibel sonic alarm pierces the silence to let you know it’s working, or switch to the ultrasonic frequency to make your corrections in silence. Uses one 9-volt battery (not included). Pistol grip and laser indicator offers precise focus of the sound wave.
