Training Instruction :
1. Adjust the pitch & blow the whistle to your dog. But even dogs can′t hear all frequencies (your whistle has a nut and screw that adjust the frequency when turned). You may want to wait until he is asleep and gently blow on the whistle.
2. Continue testing until your dog perks up. You will then know you have reached a frequency he can hear.
3. Use the dog whistle with varying sequences to train your dog. For example, one long burst can mean "come", while a series of short, staccato bursts might mean "sit".
4. Keep your whistle commands consistent and your dog will always know what you expect of him.
Change your dog’s behavior through training. For instance, at meal time, blow on the whistle before they get the food. It will only take a few attempts doing this before your dog gets good at it.

COMMON SITUATION -- At first, sometimes dogs may not respond to dog whistle, because each dog likes a different length of ultrasound, so we still need to adjust the wavelength of the sound of the dog's whistle. Another situation is that the dog actually hears the sound, but does not think it is a voice that needs to be responded. This requires our training, such as giving a dog snack after whistling. Normally, the training period is 2-6 months. You need enough patience to repeat your dog.
