An automobile with a function of preventing harassment of dogs is provided with one or more ultrasonic dog-expelling devices. The ultrasonic dog-expelling device is composed of an ultrasonic generator, a control circuit unit, an ultrasonic transducer assembly, connection cables and the like. The ultrasonic transducer assembly of the ultrasonic dog-expelling device is installed at an outside rear-view mirror outside the automobile or a rear-view mirror support, and is provided with two ultrasonic transducers, and the two ultrasonic transducers face the centers of front wheels and centers of rear wheels of the automobile respectively. The ultrasonic generator and the control circuit unit are installed inside an automobile cab. When the ultrasonic generator works, the ultrasonic transducers generate 25kz ultrasonic waves, a strong ultrasonic wave action zone is formed near front tires and rear tires, the sound pressure of the ultrasonic waves can reach above 100db, so that a pet dog trying to get close to the tires is stimulated by the strong ultrasonic waves and leaves, and therefore the behavior that the pet dog pees at (or rubs) the tires (including the automobile body) and other behaviors harassing the automobile are avoided. The ultrasonic dog-expelling device can also be used for additional installation and refitting of an existing automobile. Due to the fact that ultrasonic waves within the range where the auditory sense of the pet dog is sensitive are adopted, harmful influence on people is avoided. Besides, the ultrasonic dog-expelling device avoids environmental pollution possibly caused by chemical dog-expelling agents and inconvenience brought about by repeated spraying, and has good use value.
