The biggest barkers are usually the smallest dogs. The new PetSafe UltraLight Sonic Bark Collar box weighs only one ounce, so it can be worn by any size dog. It snaps right on to your pet's existing collar so he doesn't have to wear a second collar. It's adjustable sensitivity levels allows you to customize it to recognize your dogs unique bark.
When your dog begins to bark, the bark collar receiver recognizes the unique pattern. The bark control box then emits a loud sound that startles your dog, disrupting its barking and discouraging it from continuing. While very effective, it is perfectly harmless.
Your dog soon learns that barking causes the unpleasant noise, stops barking, and the training is complete.
