The collar is completely harmless, and looks like a normal collar with a little box in the middle. The little box goes under the throat and at the first sign of barking it will emit a spray which is repugnant to your dog but smells lovely to us (well I like it ).

When I worked with Roger Mugford, he used it to great affect. You may want to try buying one on sale or return Stop Your Dog Barking with the Aboistop Anti-Bark Collar.
