What Your Dog’s Tail Wag Direction Means

Dogs are able to express their emotions just like humans do, only slightly differently.   Instead of a smile or a frown, dogs wag their tails to show what they are feeling.   An interesting fact is that the direction in which your dog’s tail wags can mean certain things.  Dogs have left and right brains that are responsible for movement, emotions, etc.  The left side of their brains affects the right side of their bodies and vice versa.

Italian researchers, Giorgio Vallortigara of the University of Trieste,  Angelo Quaranta and Marcello Siniscalchi of Bari University, came out with a study that said when a dog wags its tail to the right, it is happy, but when it wags its tail to the left it is unhappy or frightened.   The researchers performed tests on 15 female and 15 male dogs, to see how they would react to different stimuli including their owners, a stranger, a cat, and a dominant dog.  Each stimulus got a slightly different reaction, with the owner getting the most tail wag to the right, and the dominant dog getting the most tail wag to the left.

Something fun to think about when you approach your dog next time.  Check out his tail to see which way it’s wagging!  I’m not bragging or anything but mine always wag to the right!

What if it goes round in circles – as your ‘nephew’, Buckley, does all the time? Maybe that means he is just ecstatic?

It sure sounds like wagging bragging to me! Interesting study.
