Dog bark control and training device provides safe and effective behavioral training aids for dogs. The device emits ultrasonic waves ranging from 20 to 25 kHz, which are beyond human hearing but can easily attract a dog's attention without harm, similar to a dog whistle. It's safe for correcting unwanted behaviors, stopping barking, and preventing unsafe food consumption. It's an effective pet corrector for dogs of all types and sizes aged 6 months to 8 years.

The dual-headed sonar device covers up to 10 meters/32 feet, offering more power and effectiveness than single-headed versions available on the market. This electronic dog whistle is equipped with a rechargeable 800mAh battery, providing a full charge in 1 to 2 hours for 30 days of regular use.

There are two modes: the deterrent mode, which emits a high-intensity ultrasonic sound with a flashing light to ward off aggressive dogs, and the training mode, which emits a lower-intensity ultrasonic sound to aid in daily dog training, such as stopping excessive barking, fighting, biting, and correcting other unwanted behaviors. The flashlight also has a bright long mode for walking your dog at night.

Its slim design with an anti-error lock switch makes the collar a better fit even for smaller hands. Independent and clear keys facilitate easy use, and the anti-error lock key prevents false triggers. The collar also comes with an adjustable wrist strap for outdoor use.

Pressing the button on the ultrasonic device also has a vibration effect, providing a better experience. The button light indicator turns red when the power is low.
