Dog Bark Deterrent Devices, Anti Barking Device for Dogs – Dual Ultrasonic (Fixed 25 kHz/Adaptive 20-30 kHz), Up to 50 FT Bark Control, Humanely Stops Neighbor’s & Own Dog Barking (Blue)

【Digital Display & Long Battery Life】This anti barking device for dogs features a clear digital display that shows battery level and operating mode in real time, eliminating guesswork. The combination of fast charging and extended standby time means you can spend more time training, with a standby time of up to 60 days. 【Night Walk Ready】Built-in high-brightness flashlight with two modes: steady light for safe nighttime visibility, and strobe mode for added deterrence when encountering unfamiliar dogs. Effective up to 50 feet, suitable for both indoor and outdoor training. 【Smart Safety for Sensitive Ears】A built-in 10-second automatic stop function limits prolonged ultrasonic exposure, preventing overstimulation or discomfort, balancing efficient training with long-term hearing protection for your dog. Designed for safe, repeatable daily use. 【Dual Ultrasonic Technology】Choose a fixed frequency of 25 kHz for consistent daily training, or switch to an adaptive frequency of 20-30 kHz—the frequency changes automatically to prevent dogs from adapting to the sound. Smarter training, longer-lasting results—because a single frequency is not suitable for all dogs. 【Gentle Guidance, Not Punishment】No electric shocks, sprays, or any painful stimulation required. Our ultrasonic dog trainer gently and effectively stops undesirable behaviors such as barking, biting, and jumping. Safer than an anti-bark collar, more effective than a whistle, and suitable for all breeds.
