If you've ever looked at a dog and had a feeling it was judging you, chances are it probably was!
A recent study published in the Neuroscience and Biobehavioral Review, claims that dogs are aware of human body language and take note when that language is negative.
“Dogs are known to consistently follow human pointing gestures. In this study, we asked whether dogs ‘automatically’ do this or whether they flexibly adjust their behavior depending upon the reliability of the pointer, demonstrated in an immediately preceding event” the researchers said.
“These results suggest that not only dogs are highly skilled at understanding human pointing gestures, but also they make inferences about the reliability of a human who presents cues and consequently modify their behavior flexibly depending on the inference.”
As an added bonus, if you're not quite sure about someone, maybe see how your dog reacts to them as they might be picking up on some subtle signals you've been missing.
So while we tend to watch our behaviour around kids, it might pay to keep an eye on things when dogs are around too!
