【Gentle Bark Control: Become a Good Dog Owner】 Are your neighbors complaining about your dog's excessive barking at night? Does he bark incessantly around guests? Is he aggressive towards passersby on walks? This ultrasonic bark control device uses scientifically safe ultrasonic frequency conversion technology that won't damage your dog's hearing and gently corrects unwanted behavior. Rechargeable and portable, it simplifies training and promotes better relations with your neighbors. 【Scientific Frequency Conversion, Three Modes Available】 Unlike traditional bark control devices with only one frequency, this dog training device uses ultrasonic frequency conversion technology and automatically adjusts the frequency to your dog's response to prevent habituation. Three flexible modes: Mode 1 – Ultrasonic Bark Control: If your dog barks excessively, press the button to emit ultrasonic waves and stop the barking. In combination with command training, this mode allows for the gradual establishment of the conditioned reflex "calm = reward." Mode 2 Ultrasound + Flashing LED: Ultrasound combined with a flashing light is ideal for correcting inattentiveness or when the dog is out of range. It provides both visual and audible signals. Mode 3 LED Night Light: The separate LED light illuminates the path during nighttime walks and can also serve as a light source to attract the dog's attention. [Safe and Pet-Friendly Design] Ultrasound consists of high-frequency sound waves that are virtually inaudible to the human ear but have a gentle, attention-grabbing effect on dogs. It does not produce electric shocks or pain; it simply interrupts the dog's unwanted behavior with an audible signal, allowing the owner to give commands. Suitable for dogs of all sizes, even small, sensitive dogs can use it safely.
