The  PetSafe  Spray Bark Control Collar (Citronella Like Bark Collar) effectively and humanely stops barking when it is worn. When the vibration of your dog’s bark triggers the Sensor Probe, a burst of lemon-scented spray is emitted to deter the barking.

You should notice a reduction in your dog’s barking within the first couple of days that he wears the PBC00-11005 Petsafe Lemon Spray Bark Control Collar. At this point, it is important to remember the learning process is still not complete. Dogs will “test” this new learning experience and will increase their attempts to bark. This usually occurs during the second week a dog wears the PBC00-11005 Petsafe Lemon Spray Bark Control Collar. If this does occur, remain consistent and do not alter your use of the PBC00-11005 Petsafe Lemon Spray Bark Control Collar. You must place the PBC00-11005 Petsafe Lemon Spray Bark Control Collar on your dog in every situation when you expect him to be quiet.
