They also use their tails as rudders when pulling a sled across the ice. When lying down they may pull their tails over their faces to keep out the cold. Nordic and Arctic breeds have bushy or plumed tails with long dense fur. Some dogs use their tails for insulation. Dogs bred for swimming frequently have tails that are thick, strong and very flexible, which helps them to move easily through the water and make quick turns. Some dogs use their tails as rudders when swimming. Tail muscles are also important in stabilizing the vertebral column and supporting the action of the extensor muscles of the back, as well as those of the croup and buttocks. Their tails may increase their agility and ability to turn quickly, so they can keep up with their prey. Dogs that run at great speeds often have thin tails that are very long in proportion to the rest of their body, and they use their tails as a counterbalance when making turns. The tail is important as a means of counterbalance when the dog is carrying out complicated movements such as leaping, walking along narrow structures or climbing. Likewise, a frightened dog holds his tail between his legs to keep others from sniffing him, and in that way does not draw attention to himself. A dominant dog that carries his tail high will release much more scent than a dog that holds his tail lower. Every time the dog wags his tail, the muscles around the anus contract and press on the glands, causing a release of the scent. One of his most important odors comes from the anal glands, two sacs under the tail that contain a smelly liquid that is as unique among dogs as fingerprints are to us. Every time your dog moves his tail, it acts like a fan and spreads his natural scent around him. The tail has another vital role in communicating. A tail that is low and wagging indicates the dog is worried or insecure. When the tail goes from horizontal to upright and becomes rigid, he is feeling threatened or challenged. A tucked tail indicates the dog is frightened or submissive. When he is interested in something, his tail is usually horizontal to the ground. When a dog wags his tail high and wags it back and forth, he’s usually feeling pretty good. By looking at the position and movement of the tail, you can often tell what dogs are thinking. They express happiness, aggression, stress and many other emotions with their tail. You can tell a lot about what dogs are feeling by watching their tails. What Are the Functions of the Canine Tail? These muscles have many tendons that insert from the fifth or sixth caudal vertebra, then onto the next vertebra, and so on to the end of the tail. Four to seven paired nerves serve the tail muscles. Part of the musculature is formed from muscles associated with the rectum, the anus and the pelvic diaphragm. The most posterior tendons attach to the last tail vertebrae. The muscles are attached to the tail vertebrae by tendons. The muscles insert on the tail/caudal vertebrae exclusively. The caudal muscles lie on the lumbar vertebrae, sacrum (in the lower back region) and tail vertebrae. These vertebrae are enclosed by a versatile musculature that make the various segments, especially the tip, capable of finely graded movements that lift the tail, move it from side to side, or draw it down toward the anus or between the hind legs. The canine tail usually consists of between six and 23 highly mobile vertebrae. What Is the General Structure of the Canine Tail? In these breeds, a long tail is considered a disadvantage or a hazard, depending upon the dog’s intended usage or line of work. Dogs without tails and those whose tails are commonly docked often belong to the herding and working breeds of dogs. Other dogs have their tails docked short soon after birth. Some dogs are born with short, rudimentary tails. It is the hind-most part of the backbone. The tail is located at the end of the vertebral column. It extends beyond the trunk or main part of the body. The tail is the most posterior or caudal terminal appendage of the vertebral column on a dog.
