当谈到狗摇尾巴时，一些问题仍然困扰着研究人员。
研究人员在一篇新的科学文献综述中指出，我们知道家养狗(Canis familiaris)用尾巴与其他狗和人类交流，甚至还知道各种摇尾的含义。动物行为学家西尔维娅·莱奥内蒂及其同事在1月17日的《生物学快报》上报告说，但我们不知道为什么狗似乎比其他狗更爱摇摆，甚至不知道这种摇摆在多大程度上受它们的控制。

They also hypothesized about the behavior’s origins: Perhaps tail wagging placates some human need for rhythm, the researchers suggest, or maybe the behavior is a genetic tagalong, a trait tied to others that humans bred into domesticated dogs. “People think wagging tail equals happy dog. But it’s actually a lot more complicated than that,” says Emily Bray, an expert in canine cognition at the University of Arizona in Tucson who was not involved with the work. Understanding why dogs wag their tails is important partly from an animal welfare perspective, she says, as it could help dog owners read their pups’ cues better. One main thing that researchers know about tail wagging is that it’s used predominantly for communication instead of locomotion, like a whale, or swatting away bugs, like a horse. Wagging also means different things depending on how the tail is wagged, such as its height or side-to-side movement. For example, when the tail wags more to the right, the researchers say, it typically means the dog is interested in a stimulus or wants to approach something. But when it wags more to the left, it signals uncertainty or wanting to withdraw. When wagged low and near the legs, it’s a sign of submission or insecurity. Dogs can interpret and react differently to these varied wags (SN: 11/1/13). But for such a ubiquitous behavior, questions abound. One gap is how much tail wagging is under dogs’ conscious control, the team reports. Several studies have also observed that dogs wag their tails more than other canines, particularly compared with their closest relative, the wolf (C. lupus) — but scientists don’t yet know why. One idea is the domesticated rhythmic wagging hypothesis, Leonetti and colleagues suggest. Scientists know that humans’ brains respond positively to rhythm, and because tail wagging is a rhythmic behavior, the authors suggest it could be that humans consciously or unconsciously preferred dogs that wag more. Or the domestication syndrome hypothesis could be at work. It’s an existing theory that unintended, genetically linked traits can pop up when specific traits are bred for through domestication. Perhaps, the researchers propose, the canine characteristics that humans found desirable to breed for — such as temperament — might be genetically linked to tail wagging.? Evolutionary biologist Tom Reimchen isn’t so sure about either hypothesis. He’s skeptical that domestic dogs do wag their tails more than other canines. More research is needed to compare tail wagging between nondomestic canine species and the epigenetic influences behind? canids’ tail wagging, says Reimchen, of the University of Victoria in British Columbia. Leonetti, who did the work while at the Max Planck Institute for Psycholinguistics in Nijmegen, Netherlands, says a multidisciplinary approach would be helpful in future tail wagging research, for example combining neurology, cognition and physiology. Because the domestication process was also an evolutionary process — one humans were involved in — studying dog behavior and their wags could reveal something about us too, she says (SN: 9/7/22).? It “can shed light not only on our understanding of dog behavior, but also we’ll then understand something about human psychology.”
