Do Dogs Have Feelings in Their Tails? Facts Explained

Dogs, often referred to as man’s best friend, are highly expressive creatures. Their wagging tails are one of the most noticeable aspects of their body language. But have you ever wondered if there’s more to a dog’s tail than just a mere indication of excitement or happiness? 

In this article, we will explore the fascinating world of canine tail language and emotions, delving into scientific studies and expert insights to shed light on the question: Do dogs have feelings in their tails?

Understanding Canine Tail Anatomy

Before we delve into the emotions associated with a dog’s tail, it is essential to understand the tail’s anatomy. The tail is an extension of a dog’s spine, consisting of several vertebrae, muscles, and nerves. 

Different dog breeds have varying tail lengths and shapes. Some breeds have naturally long, wagging tails, while others have shorter, bobbed tails or tails that curl over their backs.

Tail Wagging: More Than Just Happiness

Contrary to popular belief, tail wagging is not always a sign of happiness. Dogs use their tails to communicate a range of emotions and intentions. For instance:

Happiness and Excitement: A loose, wide tail wag with a gentle side-to-side motion often indicates a happy and excited dog. This tail movement is usually accompanied by a relaxed body posture and a friendly demeanor.

Nervousness and Anxiety: A tucked tail, positioned between the hind legs, signals fear, anxiety, or submission. This is often seen in dogs facing unfamiliar situations or encountering aggressive individuals.

Aggression and Dominance: A stiff, upright tail wag with limited movement can indicate dominance or aggression. This type of tail wag is usually accompanied by other aggressive body language, such as raised hackles and a tense posture.

Curiosity: A slow wag, with the tail held horizontally, suggests curiosity and interest. The dog is assessing the situation and deciding whether it is safe to approach.

Warning: A rapid, short wag with the tail held high can be a warning sign. It’s essential to read other body language cues to understand the context fully.

Scientific Insights into Canine Tail Emotions

Research on canine behavior and emotions has provided valuable insights into the significance of tail movements. 

A study published in the journal “Current Biology” in 2013 revealed that dogs could differentiate between various tail wagging patterns. 

When shown videos of other dogs wagging their tails to the left or right, dogs responded differently depending on the direction of the wag.

Tail wagging to the right was associated with positive emotions and friendliness, leading to a relaxed response from the observing dogs. 

In contrast, tail wagging to the left was perceived as negative or threatening, triggering a stress response in the observing dogs.

These findings suggest that dogs are not only highly attuned to tail movements but also capable of understanding the emotional cues conveyed by other dogs through their tails.

The Role of Oxytocin

Oxytocin, often referred to as the “love hormone” or “bonding hormone,” plays a crucial role in fostering social connections and emotions in both humans and animals.

Studies have shown that when dogs and their owners interact positively, oxytocin levels increase in both parties. 

It is believed that this hormonal surge reinforces the emotional bond between dogs and their human companions. In a study published in the journal “Animals” in 2019, researchers found that when dogs gaze at their owners, their oxytocin levels rise. 

Furthermore, when owners gaze back at their dogs, the dogs’ oxytocin levels increase even more. This mutual gaze helps strengthen the emotional connection and feelings of trust and love between dogs and their owners.

Considering that a wagging tail can often accompany these positive interactions, it is plausible that the tail’s movement is influenced, at least in part, by the release of oxytocin during these bonding moments.

Tail Docking and its Impact on Emotional Expression

Tail docking, the practice of surgically removing a puppy’s tail shortly after birth, is a controversial topic. 

While historically done for practical purposes, such as preventing injuries to working dogs or conforming to breed standards, the procedure is now widely criticized for its potential adverse effects on a dog’s emotional expression.

Tail docking removes a vital means of communication for dogs, limiting their ability to convey a full range of emotions through tail movements. 

As a result, tail-docked dogs may experience difficulty expressing themselves adequately and understanding the emotions of other dogs.


In conclusion, a dog’s tail is much more than just a floppy appendage; it serves as a vital tool for communication and emotional expression. 

From happiness and excitement to fear and aggression, dogs utilize their tails to convey a broad spectrum of emotions and intentions.

Understanding canine tail language is crucial for interpreting a dog’s feelings accurately and responding appropriately. As responsible dog owners, it is essential to respect and appreciate this unique form of communication. 

By recognizing the emotional significance of a wagging tail, we can forge deeper connections with our canine companions, enriching our relationships and promoting a more harmonious coexistence with these loving creatures.

So, the next time your furry friend wags their tail, remember that there’s a lot more to it than meets the eye – it’s a window into their heart and soul.
