Italian scientists have shown that when a dog feels fundamentally positive about something or someone, their tails wag more to the right of their rumps. When they have negative feelings, their tails wag with a portside bias.
It basically confirms of what scientists already know about brain assymetry in humans and other animals.
In most animals, including birds, fish and frogs, the left brain specializes in behaviors involving what the scientists call approach and energy enrichment. In humans, that means the left brain is associated with positive feelings, like love, a sense of attachment, a feeling of safety and calm. It is also associated with physiological markers, like a slow heart rate.
At a fundamental level, the right brain specializes in behaviors involving withdrawal and energy expenditure. In humans, these behaviors, like fleeing, are associated with feelings like fear and depression. Physiological signals include a rapid heart rate and the shutdown of the digestive system.
What's interesting about this study is that the tail is smack dab in the middle, so would it follow the pattern? And the answer is that it does.
And now it's your turn, "Speak". What does Belle have to say about that?
