Why Do Dogs Wag Their Tails?
Dogs wag their tails to communicate how they are feeling. It is often thought that tail wagging shows that dogs are happy but there is much more being communicated. Dog’s tails are an important communication tool and their position can indicate nervousness, excitement, relaxation, and more.
The Importance Of Tails For Canine Communication

Dogs wag their tails instinctively and it is an important part of canine communication. Puppies will start to wag their tail within the first month of life. Tail wagging is a way for dogs to show how they are feeling and this ranges from excitement to nervousness.
Dogs that have had their tail docked are at a disadvantage when it comes to communication. This is due to not having a tail makes it harder for others to interpret how the dog is feeling.
Having a docked tail makes it more likely for the dog’s intentions to be misunderstood. This is why it is important to take into account other aspects of the dog’s body language to help avoid miscommunications.

When looking at a dog’s tail position it’s important to also observe their body language and the situation. This will help you more accurately understand how your dog is feeling.
When a dog’s tail is in its natural position without wagging it is a sign of them feeling relaxed. For most dogs, a neutral tail position is hanging down near their back paws but for some breeds, the tail is naturally curled up over their back.
Broad, Sweeping Tail
A broad, sweeping tail is not tucked or held high. This is an indication that the dog is comfortable and relaxed.
High, Wagging Tail
When a dog is holding their tail high and is wagging it fast it indicates excitement.
Common examples of this are when the dog sees something that excites them such as a friend visiting the house or a cat passing through the garden. When dogs are this excited their behaviour may be more erratic than usual.
When the tail is moving in circular motions it indicates the dog is feeling social and excited. This tail movement is usually seen around close friends and is a sign the dog is very pleased to see you.
Backwards, Gently Wagging
When a dog’s tail is held backwards and is slowly wagging the dog may be curious but unsure of the situation. Common scenarios where this tail position is seen include when a dog is looking at an unfamiliar object trying to figure out what it is.
When a dog tucks their tail or is slightly wagging it but holding it low it is a sign that they are worried. This tail position is used to communicate to others that they are not a threat.
When the tail is not just tucked but is clamped between the dog’s legs it shows they are very worried. A dog with a clamped tail most likely feels the need to protect itself.
If the dog’s tail is high and rigid, this can be a sign of aggression. The dog is letting others know that they need space and a chance to calm down.
Tail Wagging To The Right
Research suggests that when a dog wags their tail slightly to the right it can indicate the dog is relaxed and recognises the person or dog.
Tail Wagging To The Left
The study also showed that when the dogs wagged their tail slightly to the left it would indicate anxiety and more negative emotions.
Side to Side Wagging
When dogs are focussing on a scent they may move their tails from side to side. This is not thought to be communication but is likely to be a sign of concentration.
