Features: Great alternative to electronic bark-control collars Small, lightweight bark-sensing unit Humane, safe and effective bark control Based on the idea of correcting unwanted behavior with disruptive stimulus rather than punishment. The citronella spray technology in this collar provides a safe, effective and humane means of bark control. Barking activates the small collar-mounted unit, which releases a brief spray of citronella. The sound, feeling, sight and smell of the spray distracts the dog and disrupts barking. Dogs associate the spray with barking and quickly learn that they can avoid the spray by being quiet. Collar unit weighs 2.14 oz and measures 2" x 1.5" by 1.5". Includes: adjustable nylon collar (8"-24"), electronic bark-sensing unit, two 6-volt batteries, two extra cans of citronella (good for approximately 600 sprays) and tool to adjust spray.
