You can understand a lot about your canine companion from their dog tail signs. That wagging or thumping on the carpet? You know your pup is feeling great. That feeling of dread when you walk through the front door and that same tail is tucked low? That tail tells you something has been destroyed by a bored pup while you were away. Whether you consider yourself fluent in wag or you're still learning how to decode dog tail language, read on to learn more about how your pet communicates.

A dog's tail originally evolved to help with balance, like a tightrope walker's pole. It serves as a counterweight to the front part of the body when making a high-speed turn while hunting and helps keep them from falling off narrow walkways.
Now that a dog hunt generally involves finding the last piece of kibble that fell behind the bowl, that wagging tail is largely thought of as a communication device. Here are five key things the placement of a dog's tail can tell you, according to the Center for Shelter Dogs at Tufts University Cummings School of Veterinary Medicine.
The speed of a dog's wagging tail might also give you an indication of their mood, Psychology Today reports.

Some dogs wag with long, expressive tails, but what about dogs with small, stumpy tails? A truncated tail may make it more difficult for dogs to communicate with their pet parents and with other dogs, writes Psychology Today. An observational study of more than 400 dogs greeting each other off-leash in a dog park showed a higher number of aggressive incidents involving dogs with short tails. This doesn't mean that your corgi will inherently pick more fights than your shepherd mix, but it could be something to watch out for. Overall, the study found that only 12 percent of dog park incidents resulted in any kind of aggression. That's a sign that dog communication has a pretty high success rate.
The tale of the tail? Dog tail signs help pups communicate not only with us, but also with other dogs. Knowing the meaning of how a dog is using their tail can go a long way to showing you how your pet is feeling.
