It can be pretty unnerving to have dogs in the neighborhood bark their heads off in the middle of the night with no apparent reason to do so, which is why the Bark Free Pro comes in handy. This device uses ultrasonic sound output that is effective up to 30 feet, while the Super Bark Free is good up to 50 feet, being powered by four D batteries. The Deluxe Digital Bark Free Pro synchronizes four speakers together, giving you "quad damage" so to speak and is good up to 60 feet. All three products are water resistant and turn on automatically whenever barking begins and off when all is quiet. Prices range from $69.95 to $119.95, depending on the model purchased.
