The PetSafe Ultralight Sonic Bark Collar weighs only one ounce, so it can be worn by any size dog. The Sonic Bark Collar snaps right on to your pets existing collar so he doesn't have to wear a second collar.

The Sonic Bark Collar's 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. While very effective, it is perfectly harmless.
