Bark Free Anit-Bark Device by Lentek

Bark Free is one of the best dog bark silencers on the market today. The dog barking alarm provides the simplicity and convenience of dog bark training without the hassle or expensive cost

Eliminate noisy and irritating barking with this bark control device. This is a professional tool for training your dog to stop barking at times when it is really not necessary. Bark Free is designed to make your dog training as convenient for you as possible, by automating when your dog is reprimanded for barking.  The anti barking device is ideal for people in quiet neighborhoods, a family with a new pet, or someone who has had enough of the neighbor’s barking dogs.

Bark Free is a dog training device that features a microphone and a speaker capable of producing ultrasonic sound.  When the microphone registers a dog bark, the speaker goes off, producing a sound that startles a dog and ceasing its barking.  The dog barking deterrent makes training easy and simple, and it eliminates the need for rolled-up newspapers or shouting.

The microphone can even be adjusted to register at different decibel levels, ensuring that the barking dog alarm will not accidentally sound if a car passes.  The bark control device’s speaker can be adjusted to produce only ultrasonic sound, or even a lower frequency sound that humans can hear, if you wish to interact with the dog at the time of its barking.

Bark Free runs on AC power, comes with a 50 foot extension cord and a vinyl rain cover, allowing you to take it inside or out.  The barking dog training product is backed by a one year manufacturer’s warranty, ensuring that it will work to assist with your dog bark training.
