Reportedly, via adweek.com, this ad involves high-pitch sounds that only a dog — the perceived actual customer for the product, Bakers brand dog food — can hear. It’s an approach, according to adweek.com, that Nestlé Purina PetCare took previously. The question is whether this is a situation where knowledge of the consideration of including sounds for the dog is enough to convince the actual customer — the dog owner/guardian, who purchases the food — to have a positive association with the brand.
