Dogs are able to distinguish the face of a dog from the face of any other domestic or wild animal . And also, they consider it within the mental category of "belonging to the same group", according to a study just published in the journal Animal Cognition .
Individuals of the same species meet to carry out social life. That implies recognizing similarities between individuals of the same species. To date, research suggests that many species are more attracted to images of individuals in the same group. In the case of domestic dogs ( Canis familiaris ), which have the greatest morphological variety in the animal world (400 different pure breeds have been registered) Dominique Autier-Dérian and his colleagues from the Lyon National Veterinary School (France) have shown that this does not pose any difficulty for them to recognize each other through photographs displayed on a screen (that is, without olfactory or other references). In other words, their brains are capable of creating a visual category of "dog faces."
