This is kind of exciting for dog lovers everywhere, and probably a little disappointing to animal non-equalists:
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.[ via orange ]
