Every dog owner wishes they could speak with their furry family member, but for now, the best we can do is read their body language. Pet care experts have studied the connection between dog behavior and mood for as long as humans and canines have lived together, and one of the best indicators of attitude is tail wagging. The guide below reveals the reasons behind tail wagging and what your companion could be telling you.

Why Do Dogs Wag Their Tails?

Like many animals, the original purpose of a dog’s tail was to assist with balance, primarily while hunting. While they can still use this balancing tool as they run, modern domesticated dogs primarily move their tails to communicate. 

Most dog owners will see tail wagging in response to something exciting, like food or a walk. However, tail movements can have many meanings. Watch your dog’s body language and the way their tail is moving or positioned to interpret your pet’s mood.

How Can You Interpret Tail Wagging?

A relaxed or slightly raised tail and moving back and forth is usually a sign of a happy pup, especially if their body is flowing with the motion of the wagging.  An excited dog’s tail might wag stiffly as they jump or bow, a common invitation to play. If the tail is straight out horizontally, this could indicate that your dog is curious or alert.

When a dog is indicating submission, their tail lowers. A scared dog may tuck their tail between their rear legs. If your dog seems relaxed but suddenly raises their tail to a vertical position, be alert—this could indicate discomfort or aggression. In general, the higher the tail, the more aggressive and territorial they're feeling.

Movement and speed can also tell dog owners a lot about canine body language. Big and wide wags show comfort and friendliness. A faster, but still wide wag shows excitement, especially during playtime. 

If the motion seems slow and hesitant, your pet may be feeling tentative or anxious about meeting a new person or animal. A rapid and narrow wag that almost seems to vibrate shows discomfort. This can be a precursor to aggression, so keep your distance if you see a dog demonstrating this behavior.
