Wish you could read your canine companion’s mind? Just pay attention to his tail wagging. According to a study released by Current Biology, whether your dog’s tail wags more to the left or right matters a great deal. If the tail veers more to the left, your furry friend may be stressed.
Conversely, if the tail wags more to the right, your buddy is probably relaxed and cheerful. As Prof Georgio Vallortigara, a neuroscientist from the University of Trento, explains, the right and left side of the brain perform different functions in both human and animals. The different sides of the brain ‘are differently involved in stimuli that invokes positive or negative emotions. Here we attempted to look at it in other species’.
