Stop his barking, but honor his personality. Dogs have different temperaments. This innovative collar has 3 correction modes, each with 6 levels of stimulation, so you can fine tune according to the unique needs of your pet. If you choose, correction levels can also be set to automatically increase after each subsequent bark.

The PetSafe Deluxe No Bark Dog Collar features our patented Perfect Bark Technology simultaneously sensing both sound and vibration, and only a combination of sound and vibration will trigger the electronic correction. The PetSafe Deluxe Anti Bark Dog Collar accurately detects your dog's bark every time. Some dog bark collars detect barking with a microphone and activate on sound, these can be set off by other noises or by another dog's bark. Some bark collars use only vibration, these can be set off by motion or jostling. Only the PetSafe Deluxe Bark Control Collar with Perfect Bark Technology ensures fool-proof bark detection.
