1. Effective Ultrasonic Dog Bark Deterrent Device: This portable anti barking device for dogs emits 15000HZ 30000HZ ultrasonic waves to instantly stop barking and deter aggressive dogs during outdoor use, providing safe protection against dog attacks. It is mainly used to prevent being attacked by dogs when going out. It can produce strong stimulation to dogs and cats (which human ears cannot hear), causing discomfort and unbearable interference to animals. 2. Intelligent Ultrasonic Technology for Dog Training: As a versatile dog training device, our bark deterrent device uses smart ultrasonic waves that intensify as animals approach, forcing them to flee in panic; ideal for both driving and training dogs, with ABS material ensuring durability and reliability. 3. Long Lasting Battery TypeC Charging: Features extended battery life for continuous operation, with a convenient Type C charging port for quick recharges; an LED indicator warns when voltage drops (e.g., dim light), so you can charge promptly to maintain ultrasonic dog bark deterrent performance. 4. Portable Design with LED Light for Easy Use: Compact and lightweight, this dog deterrent device includes a built in LED lamp for visibility in low light conditions, making it for travel; avoid deliberately teasing dogs to preserve effectiveness, as repeated exposure reduces impact.
