Do your corrections lack the desired effect to stop your pet barking? Perhaps, this deluxe spray control system from PetSafe is a good solution for you: this simple and easy-to-use bark control collar will train your dog to stop his annoying behaviour with a completely natural, unscented and harmless spray to discourage excessive barking. The bark control collar has a unique patented sensor that provides the most reliable bark detection. Via the Perfect Bark™ technology, it employs both vibration and sound sensors (patented Dual Detection) to discriminate each bark from other external noises. Only if both the vibration from the vocal chords and the sound from the bark coincide, the unscented spray will be emitted to deter barking. There are no external controls or adjustments you have to make: training has never been so easy! Powered by a 3-volt battery (included), the collar has a low battery indicator, as well as a low spray LED indicator to show you the operating state at any time. This compact bark control collar is suitable for dogs with a maximum weight of 26 kg.
