We all know Nestle for their chocolate, but didyou know they are also one of the world's biggest producers of pet food. And,  they are the world's first company to give us a TV commercial designed especially for dogs, using a high-frequency tone to grab their attention. Nestle asked experts to research what would appeal to dogs and used the results to create the  commercial for its Beneful dog. The commercial, on Austrian television this week, it features a tone similar to a dog whistle, which humans can barely hear. The spot ends with the tag line, "So delicious, so healthy, so happy!"
