Dogs use their tails to communicate emotions and intentions, and a wagging tail is often a sign of excitement or friendliness.
A wagging tail can be a broad indicator of a dog's mood, but it's not always a clear-cut sign.
A wag that is high and fast is often associated with excitement or enthusiasm, as seen in dogs that are eager to play or go for a walk.
Dogs may also wag their tails to signal that they feel comfortable and at ease in a situation.

Types of Wagging
A happy dog tail wag is a clear sign they're excited, often accompanied by a whole-body wiggle.
Dogs can also wag their tails in short strokes, which usually means they're anxious - not in a submissive way, but in an aroused way. This type of wagging can be seen when a dog sees something outside, like a squirrel, or when they're meeting a new person.

A dog's tail wag can also be directional, with research suggesting that wagging to the right is usually linked to positive feelings, like recognizing a human family member.
A raised and slowly wagging tail, often accompanied by a tilted head and perked up ears, means a dog is confused, curious, or interested. They're not worried, but trying to figure something out.
A low-held tail that's wagging slowly and stiffly can be a sign that a dog is feeling cautious or even aggressive.

Aggressive or Defensive
A stiff tail is a clear indication that your pup might be feeling tense and overly confident, especially in the presence of other dogs.
If your pup's tail is stiff, take a closer look at their body language. Do they have raised hackles, or is their fur standing up in the middle of their back? This can be a sign of aggression.
Raised ears and a stiff tail can also be a warning sign. If your pup's ears are raised and stiff, it's a good idea to intervene and redirect their attention.

The presence of a whale-eye, or side-eye, can also indicate aggression. If your pup is giving you a suspicious or aggressive look, it's time to step in.
Some breeds, like Shiba-Inus and Shih-Tzus, naturally have curled tails that can appear stiff. But if you're unsure, it's always better to err on the side of caution and observe your pup's behavior.
If you notice your pup growling or showing teeth, it's a clear sign of aggression and you should intervene immediately.

Submissive or Fearful
Dogs often display submissive or fearful behavior through their tail position. A low or tucked tail can indicate caution and concern about their surroundings. If the tail is curled between their legs, they may be very fearful and show submission to other dogs and people.
Fear and submission in dogs are commonly paired, and other signs of fearfulness include raised hackles, pinned back ears, shivering, enlarged pupils, and even snarling or snapping. It's essential to evaluate if your pup is in a situation that makes them scared.
Here are some common signs of submission or fear in dogs:
- Low or tucked tail
- Tail curled between their legs
- Raised hackles
- Pinned back ears
- Shivering
- Enlarged pupils
- Snarling or snapping
If you notice any of these signs, it's crucial to take caution and try to soothe your dog to comfort them.
Down and Away
If your dog carries their tail low but away from their hind legs, it's a good sign they're feeling relaxed and comfortable, especially at home.
This position is a normal tail position for many dogs, and it's what we pet parents want to see most of the time.
Your pup is at ease, which is a great indicator of a happy and content dog.
Low or Between Legs: Submissive
A dog's tail can tell you a lot about their emotional state, but it's not the only thing to look at. A low or between-the-legs tail is a clear sign of submission or fear.
If a dog's tail is low but not touching their hind legs, it means they're feeling a little insecure and uncomfortable, a little low. This is often a sign that they're trying to make their body smaller so they're not perceived as a threat.
A dog's tail can be down and away from their body when they're feeling relaxed and comfortable, but if it's low and between their legs, it's a different story. This can mean they're very fearful and may show submission to other dogs and people in the environment.

Understanding Dog Language
Understanding dog language is crucial to deciphering the meaning behind a wagging tail. A dog's tail position is just one part of their body language, and to truly understand how they're feeling, you need to observe a variety of cues.
Ear position is highly expressive in dogs, with forward and alert ears indicating curiosity or attentiveness, and laid-back ears signaling fear or submission. Each breed may have different ear positions, so it's essential to know what's normal for your dog.

Dilated pupils can indicate fear or excitement, while "whale eye" (showing the whites of the eyes) often signals stress or anxiety. Soft and relaxed eyes can be seen in content dogs.
A relaxed mouth with a slightly open jaw and lolling tongue usually means a dog is happy and relaxed. Conversely, a tightly closed mouth or visible tension in the jaw can indicate stress, anxiety, or aggression.
Dogs use their tails to communicate with both humans and other animals, and a happy wag can indeed convey friendliness and openness. But, it's essential to consider the context, as tail wagging during play is different from wagging during a confrontation.
Here's a breakdown of the different tail positions and their meanings:
By paying attention to these various signals, you can better interpret your dog's overall mood and respond appropriately. Remember, every pup is unique, so learn what tail wagging means for your furry companion specifically.
Research and Studies
A 2007 study published in Current Biology found that dogs tend to wag their tails vigorously to the right when they see their owners.
Dogs also have a bias to the right when shown an unfamiliar person, but the amplitude of the wagging is reduced compared to when they see their owners.
Their tails wag with a bias to the left when confronted with unfamiliar dominant dogs.
When faced with a cat, dogs show reduced tail-wagging movements, but there's still a slight preference for the right side.
A follow-up study in 2013 involved observing 43 dogs exposed to a video of a dog wagging their tail.
The dogs remained calm when the tail wagged to the right but showed signs of anxiety when it wagged to the left.
This suggests a link between the direction of tail movement and the hemispheric specialization of the brain.
The left hemisphere, associated with positive responses and social interactions, is activated when a dog wags their tail to the right.
Conversely, a movement to the left indicates activation of the right hemisphere, which is more linked to negative responses, fear, and anxiety.
These results suggest that dogs can pick up on differences in how other dogs wag their tails.
