Each time your dog barks, the sound-sensitive Anti-Bark Spray Collar releases a spray of harmless citronella. The spray interrupts the dog's pattern of barking. Over time, most dogs are gradually conditioned to stop barking. A safe, effective and humane way to end your dog's cycle of nuisance barking.
