Bark Control FREE is an Android application that aims to curb unwanted barking in dogs. Developed by Patrick Giudicelli, this free app emits a 12-second ultrasonic sound that can only be heard by the dog, which is activated by its barking. The startled dog will soon associate the unpleasant sound with its behavior, and the barking will be curbed. The application offers four different sounds to choose from, including ultrasound, dog, cat, and whistle. You can also disable the sleep mode of your device and adjust the ultrasound frequency.

Dogs bark for various reasons, and sometimes it can become a nuisance. This application provides a simple solution for dog owners who want to teach their furry friends that barking is only permitted under certain circumstances. With Bark Control FREE, you can enjoy a peaceful afternoon, a good night's sleep, and better relationships with your neighbors without worrying about your dog's constant barking.
