Does anyone know of a company that carries electric shock strip that you can place on a sofa or countertop. The idea is the same as the invisible electric shock fence for dogs. Summer is approaching and try as I might it is impossible to keep my dogs off my beautiful outdoor sofa. In fact I have to replace the cushions this year because they will not stay off. I thought if I could make it unpleasant with the electric strip they would finally get the message. I don't need training tips as this is really the only issue my dogs have and otherwise are trained. They just love this sofa and have claimed it for their own.
