It’s an Extension of Your Dog’s Spine

Ok, you probably already knew that. But did you know how many vertebrae are in the tail? If your dog’s tail isn’t docked, there may be as many as six or as many as twenty-three! The vertebrae are surrounded by a sheath of muscles, and these muscles allow it to move back and forth, up and down, and around like a helicopter.

It’s a Multi-Function Communication Device

We all know that the tail is one of a dog’s main ways to communicate with other dogs, and with us. A wagging tail is most often interpreted as a sign of excitement or happiness. But did you know that there are different kinds of wags? That’s right. Here are some of the different ways your dog may use its tail, and what they mean.

Wagging orientation

If your dog is wagging its tail more on the right side of the body, then it’s looking at something or someone it wants to approach. But if it’s wagging more to the left, then your dog is looking at something or someone it would rather avoid.

Wagging to the right means your dog is looking at something or someone they like.

And that helicopter wag? It means Awesome. You’re here. Now throw the ball.

Wagging speed

Wagging speed also carries information about your dog’s mood. A slow, wide swishing wag is a friendly wag. But if your dog is holding his or her tail up high and wagging quickly, it may mean that they’re feeling threatened.

Tail tucking

When a dog tucks its tail between it’s legs, it’s a submissive posture. Your dog may be frightened, or feel they’re in the presence of a higher-ranking pack member. It can also be a sign of uncertainty, stress, or worry.

Tail Talking Is Social

Did you know that dogs don’t wag their tails when they’re alone? Nope! Tail-wagging is a social behavior, and when they’re alone, there’s no need.

Pups aren’t born knowing how to talk with their tails. They start to wag at around one and a half months old, and practice on their mothers and littermates!

The Tail Helps Your Dog to Balance

In addition to helping a dog to communicate, the tail also helps a dog to keep its balance while that dog is moving. Also, when a dog is swimming, it will use its tail to steer, just like the rudder of a boat!

It’s An Aroma Diffuser

Your dog uses their tail to spread his or her scent. The anal glands produce a dog’s unique scent — like a signature perfume that tells all the other dogs who your dog is. This is why dogs sniff each other’s backsides in order to get acquainted. A wagging tail spreads this scent around, as if to announce to the world that your dog has arrived.
