2 Pack Ultrasonic Dog Bark Deterrent, 23ft Range Training Tool with Dual Frequency & 3 Modes, Rechargeable Anti Barking Device with LED Flashlight

**** The bark deterrent device has garnered a mixed reception among dog owners. For some users, the product has shown remarkable effectiveness in curbing barking behavior, particularly in dogs that are already sensitive to sound. One owner recounted a positive experience with their dog, who immediately ceased barking upon hearing the sound emitted by the device and even retreated to his bed, highlighting a quick and favorable response. This owner expressed relief, stating that the device allowed them to walk their dog without feeling embarrassed by excessive barking, offering an alternative to traditional bark collars. Conversely, not all experiences were as favorable. Some users reported little to no effect on their dogs' barking habits. One owner mentioned that while their dog's hesitation was noted when the light activated, it did not prevent barking altogether. Another customer, who owned multiple Yorkies, found that the device's light feature worked temporarily before their dogs became indifferent, rendering it ineffectual over time. This disparity in effectiveness suggests that the device may perform well with certain dogs while being less suitable for others. Overall, the bark deterrent appears to be a promising solution for some, particularly for sensitive dogs, but may not be universally effective for all breeds or behavioral types. **
