Train your dog to minimize their barking with the PetSafe Premium Bark Control Collar (PBC-302). This collar is lightweight (1.5 oz) and inhibits nuisance barking with a simple vibration sensor to detect your dog's barking.
The safe and gentle stimulation level will automatically increase if your dog's barking continues. He'll quickly learn the association and stop the unwanted behavior. Not recommended for use of more than 8 hours at a time.
