Sound-Based Training

Leveraging the principle of “Negative Reinforcement using Sound,” the Bark Free device provides a departure from traditional training methods. Instead of shocks or physical discomfort, it employs sounds as deterrents. This humane method ensures your dog’s physical well-being while efficiently addressing the barking issue.


With a barking detection capability of up to 25 feet, the device ensures that your dog’s barking won’t go unnoticed, even from a distance. This feature is especially useful for outdoor spaces or larger indoor areas where your dog might roam freely.

Customizable Settings

A feature setting it apart from many competitors, the Bark Free device boasts a sound selector. Owners have the flexibility to choose between ultrasonic frequencies, which are typically inaudible to humans but perceptible to dogs and cats, and lower sound tones that fall within the human hearing range. This allows for a tailored approach to dogs training.

Customizable Settings
