Nestle is going straight to the dogs with a new advertising campaign. The pet food manufacturer is launching a television commercial that uses a high-frequency tone to capture canine attention.  Pet behavior experts advised Nestle on the commercial for its Beneful brand.  The pitch includes a tone like a dog whistle that will be barely audible to humans.  It will also include a squeak like the noise a dog toy makes and a "ping" sound.  The commercial will air on Austrian television.
