Portable dog training device, ultrasonic anti-bark device, rechargeable, with variable frequency flashing LED light.--DTEKGAZ

Unlike conventional anti-bark devices with only one frequency, this dog training device features integrated variable-frequency ultrasonic technology. This automatically adjusts the frequency to the dog's response, preventing habituation. It offers three flexible modes: Mode 1: Ultrasonic Bark Suppression: When barking is excessive, pressing the button emits ultrasonic waves to stop the barking. Combined with command training, this mode helps gradually establish the conditioned reflex of "quiet = reward." Mode 2: Ultrasonic + LED Flash: Ultrasonic waves combined with a bright flashing light are ideal for correcting inattentiveness or when the dog is out of range. They provide both visual and audible signals. Mode 3: LED Night Light: A separate LED light mode illuminates the path during nighttime walks and also serves as a light source to help focus the dog's attention. [Safe and pet-friendly design] Ultrasonic waves are high-frequency sound waves that are virtually inaudible to the human ear but provide a gentle signal for dogs. They do not produce electric shocks or pain. It simply interrupts the dog's unwanted behavior with a sound, allowing the owner to give commands. Suitable for dogs of all sizes; even small, sensitive breeds can use it without hesitation.
