It won’t help you open a cold one, but it most certainly will stop your dog from barking at the neighbor’s cat. The Bark Deterring Spray Collar fires a proprietary (that’s code for ‘we’ll rip you off’) water based mist at your dogs snout any time he or she engages in excessive barking. The collar includes a 300 refill bottle and is good for up to 25 sprays (or barks) per fill. I guess it beats electrocuting fido. You can grab one for $50.
