Petsafe Anti-Bell Dog silencer 1 pc(s)

The PetSafe® outdoor bell control emits an ultrasonic sound. The ultrasonic sound can be heard by dogs, but is not audible to humans. The dog, who is frightened by the safe and effective ultrasonic sound, stops barking because he associates his bark with the unpleasant sound. When the dog stops barking, the ultrasonic sound signal goes out. PetSafe® outdoor Bellcontrol has three ranges and a test mode. This text is machine translated.
