How to train your dog?
Here are some useful puppy training tips you should use. The first step in dog whistle training process is to select series of commands that will be used as signals. For example: two short whistle sounds could mean the command "stop", or one long whistle sound to command "sit". To help you teach the dog, combine verbal commands with the whistle commands. So for the command "sit", give the verbal command accompanied with a dog whistle noise to connect the verbal command with a whistle sound. Applying this and other commands to the dog, you will make the understanding of whistle sounds easier.
TRAINING INSTRUCTIONS:

- Pick a frequency for positive response. Then use it the times when your pet does something right. We suggest a low frequency because they are more pleasant for pets' ears.
- Pick a higher frequency for wrong response. Use it at times when your pet does something wrong.

- You may also pick a frequency to call your pet. Use highest frequency since higher frequencies reach further.
positive response 12000Hz, short sound,
wrong response 15000Hz, short sound
call 18000Hz, about 1sec.
