Commercials have become so effective at focusing on what us human people want that we can't stop watching them. Oh scantily clad women. Oh short attention spans. Dogs can join in the brain dead fun now too, there's a commercial made with sounds only a dog can hear.
A Nestlé Purina PetCare commercial airing in Europe right now has spliced in a high-pitched sound, similar to a dog whistle, inside the commercial to capture a dog's attention. I guess once they see that commercial they'll want to eat Purina PetCare products, right? Either way, the high frequency might be able to grab a dog's attention and have the dog's owner think the dog really wants that food. Good idea!
