Why dogs tilt their heads, according to science

Scientists do not yet know exactly why dogs tilt their heads, but research suggests the behavior may be connected to attention, language processing, and responses to surprising information. A 2025 study found that dogs tilted most often when owners spoke familiar words enthusiastically, although the small sample means researchers remain cautious.

科学家尚不完全清楚狗狗为什么会歪头，但研究表明，这种行为可能与注意力、语言处理以及对意外信息的反应有关。2025年的一项研究发现，当主人用热情的语气说出熟悉的词语时，狗狗最常歪头，不过由于样本较小，研究人员仍对此持谨慎态度。
