Dog Whistle

PET哨

This utility is a dog training and a dog repellent whistle in same time. Also you can use it with other animals like cats, birds, etc.

Most pets can hear a much higher frequency than humans. As the frequency of a sound is higher it will draw more attention. Due to the limitation of phone devices we have picked a few frequencies that should work on most phones.

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.

REPELLENT INSTRUCTIONS:
When using this application as a repellent use the highest frequency. Hold button for at least 2-3sec. 
18000Hz or 20000Hz as necessary.

Most people are unable to hear sounds higher then 16000Hz. Older people even can't hear sounds over 7000Hz. Thus most of you will only hear sound at 12000Hz. Don't worry your pets will hear it.
