PetSafe Brand has launched a new behavioural product, the PetSafe Spray Bark Collar. The device features technology which identifies a dog's barking and distinguishes it from other noises, so there are no accidental spray episodes. The barking triggers a sensor, which emits a light citronella or unscented spray to distract the dog and interrupt the unwanted behaviour. The rechargeable collar is water-resistant and requires no programming. www.petsafe.com
