A new TV advert for dog food features a series of high-frequency signals beyond human hearing. Nestle Purina produced the 24-second advert, for Beneful dog food, using a high-pitched whistle, which only dogs can hear. The aim is to attract dogs to the screen during the ad which will in turn encourage owners to buy the product for them. Behavioural experts from the US researched which sounds would have the most effect on canines in front of the television screen. The advert features a dog twitching it’s ears with attention as its owner squeaks a toy duck, followed by the high frequency whistle. The sound occurs twice within the clip and is near enough impossible for any human to hear. Austria will be the first country to air the advert on national television this week.
