There was quiet some media echo in 2015 when publishing the article “Dogs can discriminate emotional expressions in human faces” ( The study was conducted at the Clever Dog Lab at the University of Veterinary Medicine Vienna, Austria. For the first time, we were able to prove that dogs are able to distinguish between human emotional faces by using their memory of how an emotional face looks like. There were several hundreds of articles all around the world (Australia, Austria, Belgium, Canada, China, Denmark, Germany, India, Indonesia, Ireland, Italy, Japan, Latvia, Lichtenstein, Malaysia, Netherlands, New Zealand, Pakistan, Qatar, Russian Federation, South Africa, Spain, Switzerland, Taiwan, Turkey, United Arab Emirates, United Kingdom, United States).

Another interesting study with media echo was conducted in Lincoln in 2017. The study with the titel “Mouth-licking by dogs as a response to emotional stimuli” ( could show that dogs respond with mouth-licking upon looking at angry human faces, suggesting that they not only have a functional understanding of the emotional state displayed but also that dogs use the visual display of mouth-licking to possibly facilitate dog-human communication.
