PetSafe Spray Bark Collar

If you're not crazy about the idea of using static correction to train your dog, PetSafe's Spray Bark Collar offers a gentle alternative. A built-in microphone detects when your dog barks, then delivers a harmless burst of stain-free hypo-allergenic spray to get your dog's attention and stop him from making noise. The collar includes a citronella and an unscented spray cartridge so you can figure out which one better suits your dog. Each recyclable canister lasts about 35-40 sprays.
