PetSafe Rechargeable Bark Control Dog Collar Navy Blue One Size

The Rechargeable Bark Control Collar decreases, and in most cases, eliminates nuisance barking, whining, and whimpering. When your dog barks the collar automatically adjusts through 15 levels of safe, but annoying static correction. As your dog learns to bark less, correction levels are reduced. The rechargeable, waterproof collar utilizes unique bark-sensing technology to only activate when your dog barks.
