• Safe for you and your dog-Different from other electric shock dog training tools, the ultrasonic anti-barking device uses the latest ultrasonic technology with a frequency of 20HZ~20KHZ. Sound does not affect humans, but it can easily attract the dog's attention and prevent their bad behavior.
• Usb rechargeable and portable size-Unlike other dog bark repellents that use AAA batteries, the ultrasonic dog bark control device with a built-in 300mA rechargeable lithium-ion battery can be used for up to 20 days without worrying about running out of power.
• Frequency modulation technology & two-in-one-the dog trainer emits high-pitched ultrasonic waves of different frequencies, which can avoid immunity to a certain frequency of ultrasonic waves after a long time of adaptation, so you can alternately use different sound waves for a period of time.
• Suitable for indoor and outdoor activities-dog barking deterrents can be used indoors to stop unwanted barking and train your puppies at home
