Using landscape and dog photographs, Friederike Range and colleagues from the University of Vienna, Austria, were able to show for the first time that dogs are capable of learning how to classify complex colour photographs and place them into categories in the same way that humans do.

"These results show that the dogs were able to form a concept, that is 'dog', although the experiment cannot tell us whether they recognized the dog pictures as actual dogs," said Dr Range.

"Using touch-screen computers with dogs opens up a whole world of possibilities on how to test the cognitive abilities of dogs."
