To call a dog or to make a trained dog do something most owners have trained their dogs to respond to certain voice signals (e.g. sit, lie, come) or whistle signals (with mouth or with special ultrasound whis- tle) in order to follow some commands. However, there are lots of disadvantages of using the voice (the owner has to rise the voice / whistle, if the dog is far away; other people may be disturbed by speaking aloud or by whistling; the owner might not be heard by the dog, if the surrounding is noisy) or of using the whistle (additional object has to be transported; a whistle can only emit one sound, therefore only one command is possible). Another problem is to repel a unleashed dangerous dog with an aggressive attitude. There is a ultrasound whistle for this problem but it can’t be used for the “normal” commands. Most people have almost always a mobile cell phone with them. That’s why it is suggested to use a cell phone to communicate with the dog. A slightly modi- fied cell phone can emit ultrasounds, which the dog can interpret as orders. An increased ultrasound intensity can be annoying for the dogs and can serve as a way to repel them.
