Tail Wagging Direction
Dogs wag their tails to communicate different emotions, and the direction of the wag can be a big clue. If the tail is wagging to the right, it's usually a positive sign, indicating friendliness and a willingness to interact socially.
Research has shown that dogs that wag their tails slightly to the right tend to be more approachable and exhibit other behaviors indicating a willingness to interact socially. This is because the left hemisphere of the brain, associated with positive-approach feelings, controls the right side of the body.
On the other hand, a left-sided tail wag is often a sign of stress or anxiety in dogs. They may be more likely to avoid or escape social opportunities when their tail is wagging to the left.
Interestingly, dogs can even decipher the meaning of the direction of a tail wag in other dogs. A study showed that when dogs were shown a video of another dog wagging its tail to the right, they tended to stay relaxed and even attempted to approach the dog on screen.

The speed of the wag can be compared to the volume of a voice, with faster wags indicating a louder "voice." Paying attention to the tail's base can help determine the tail set, or position, which is crucial in understanding the dog's emotions.
A dog's tail wag can also be influenced by their brain's hemispheric dominance, with right-sided tail wagging typically indicating friendlier and more social behavior, while left-sided tail wagging can suggest stress or anxiety.
