PetSafe Sonic Bark Collar 

The PetSafe Ultralight Sonic Bark Collar is remarkably light; only one ounce. It emits an unpleasant but harmless tone to correct your dog’s barking problem. The bark collar has a cutting-edge, bark-detection microphone, which can be adjusted to recognize your dog’s unique bark. This prevents other sounds to set it off. This bark collar is most effective when used on small dogs.

The PetSafe Ultralight Sonic Bark Collar snaps right onto the existing bark collar. The adjustable sensitivity levels allows you to customize it for your dog's unique bark. To deter barking, it emits a loud sound (similar to a smoke detector) that startles your dog, disrupting his barking and discouraging him from continuing. All while causing no harm to your dog.

• Bark Control Collar
