Here's what dogs see when they watch television

Here's what dogs see when they watch televisionDog owners often notice their pets watching televisions, computer screens and tablets. But what is going on in their pooch's head? Indeed, by tracking their vision using similar methods used on humans, research has found that domestic dogs do prefer certain images and videos.

This research indicates that dogs have a preference towards watching other canines – but our studies have also discovered that sound often initially attracts dogs towards television and other devices. Favoured sounds include dogs barking and whining, people giving dog-friendly commands and praise, and the noise of toys squeaking.

How dogs watch TV is very different to the way humans do, however. Instead of sitting still, dogs will often approach the screen to get a closer look, and walk repeatedly between their owner and the television. They are essentially fidgety, interactive viewers.

What dogs can see on the screen is also different to humans. Dogs have dichromatic vision – they have two types of colour receptor cells and see colour within two spectrums of light: blue and yellow. The use of colour within media is very important for dogs and explains why canine TV channel, DogTV prioritises these colours in its programming. Dogs' eyes are also more sensitive to movement and vets suspect that the improved flicker rate that has come from the shift from standard to high definition television has allowed dogs to better perceive media shown on TV.
