Purina has launched a 3D campaign at Callao City Lights to encourage us to feed our pets like professionals, by choosing expert, balanced nutrition, such as that offered by Purina Pro Plan. Under the slogan ‘Like a pro’, the campaign consists of two elements in which the 3D effect is achieved: firstly, when a dog approaches the screen to eat from a bowl, and secondly, when a tennis ball appears to break through the screen’s glass.
