Dogs Wag Their Tails According to Their Emotions

November 7, 2013 / No Comments

Researchers seem to continuously arrive at the conclusion that dogs wagging their tail indicate what emotions they have in their minds. In 2007, a group of Italian researchers observed that when the dog wagged its tail to the left, it showed negative emotions and when it was to the right, it showed positive emotions.

It says that when dogs usually wag their tail to the left they had higher heart rate along with signs of anxiety. Meanwhile when it is to the right, the animal is usually calm.

Both these studies seem to point to the fact that they have an asymmetrical brain just like humans. Giorgio Vallortigara, a neuroscientist at the University of Trento and a co-author of the study says, “The emotions are associated presumably with activation of either the right or left side of brain.” This means that when the dog wags it tail to the right, the left part of the brain is activated.

However, they have dismissed the idea that dogs communicate with each other by wagging their tails. Dr Vallortigara adds, “This is something that could be explained in quite a mechanistic way…. It’s simply a byproduct of the asymmetry of the brain.”
