Ultrasonic Dog Bark Deterrent – Rechargeable Anti-Barking Device for Dogs, 50 ft Range, Safe & Portable for Indoor/Outdoor Use – Blue

【Upgraded Dual Ultrasonic Technology】: Our bark deterrent device uses dual ultrasonic emitters for 5× wider coverage (up to 50 ft) than standard bark collars. It stops barking and aggressive behavior instantly using pain-free ultrasonic waves—no shocks, sprays, or physical contact required. Completely safe for dogs and humans.

【Customizable Frequencies for All Dogs】: Choose between a 25kHz fixed frequency for consistent training or a 15–30kHz variable range for stubborn or sensitive breeds. This contactless device protects hearing while effectively curbing excessive barking, chewing, and digging.

【4 Modes for Any Scenario】: Adaptable ultrasonic modes let you train pets or repel stray dogs within 50 ft. Ultra-compact and lightweight (smaller than a smartphone), it’s perfect for walks, commutes, outdoor activities, or backyard use.

【Flashlight & Vibration for Night Safety】: Equipped with a high-intensity LED flashlight to deter nighttime aggression and a vibration buzzer to reinforce training. Functions as both a walking light and a safety device after dark.

【Fast Charging & Long Standby】: A quick 2.5-hour USB charge provides up to 6 months of standby time. Battery indicator included—no frequent charging needed, always ready for use.

【User-Friendly & Protective Design】: Four dedicated buttons make mode selection easy. A side safety lock prevents accidental activation, and an auto shut-off stops emissions after 8 seconds to protect your pet from overstimulation.
