Petsafe Spary Bark Control Collar PBC19-16370
When your dog barks, the vibration sensor on the collar picks up the movement of their vocal chords. This activates the collar to deliver a quick burst of spray to your dog's snout stimulating a number of their senses. Your dog will hear the collar module release the spray, feel the mist on their snout and smell the scent of citronella (if there's a citronella scented refill in the module) all within a second of barking. This multi-sensory stimulation disrupts their nuisance barking behaviour. With consistent use, your dog will learn not to bark when the collar is on.
