pay attention:

This product triggers the product to emit ultrasonic waves when the dog barks at a certain decibel level. The ultrasonic waves will make the dog feel uncomfortable. After repeated repetitions, the dog will know the cause of his barking and stop barking.

Some dogs bark even louder when they emit ultrasonic waves to make themselves uncomfortable. This is because they haven't realized that the discomfort caused by their own barking makes them bark louder. There needs to be an adaptation process.

This ultrasonic wave has three gears. It is best to change the frequency regularly when using it, because this kind of ultrasonic wave does no substantial harm. You will get used to this frequency after a while and will not be afraid anymore, so you should switch the frequency frequently.

Strictly trained dogs and dogs with immature hearing will not be effective. Those who mind are advised to proceed with caution.
