在我们上一期内容中，我们为各位字母圈（BDSM）新人介绍了基本的小圈和大圈的区别，以及一些常见的角色如Dom和Sub。今天，我们将专注于字母圈中更多元的角色之一：K9。
1. 什么是K9？狗系角色扮演
K9在字母圈（BDSM中文社区）中，指的是BDSM亚文化中的一种角色扮演形式，意为"狗奴"或"犬类扮演"：
字面意思是"犬类扮演"，它指的是参与者通过行为、语言和心理调整，进入"犬类"角色状态，而主导者则扮演"训犬师"或"主人"的角色。跟K8（猫系）一样，也是BDSM圈子里被广泛使用的角色扮演术语。
在西檬之家看来，K9不是一个随意发明出来的词汇，而是有着深厚的BDSM文化背景的实践方式。这类角色扮演起源于对现实或幻想中宠物（尤其是狗）行为的模仿，并转化为BDSM框架中的一套互动规则。这种角色扮演类似于宠物扮演（Pet Play），但重点尤其在于强调绝对的服从与忠诚。
The K9 character in the letter circle (BDSM Chinese community) refers to a \"dog-submissive\" or "canine role-playing\" form in the BDSM subculture. K9 literally means "canine role-playing". It refers to the practice where participants, through behavior, language, and psychological adjustment, assume the role of "dogs," while the dominant party takes the role of "trainer" or "owner." Like K8 (cat-related play), K9 is a commonly used term in the BDSM community, reflecting a deep understanding of this niche interest among professionals, enthusiasts, and individuals seeking to explore their fantasies in a safe, consensual, and ethical manner.
At Lixiao Family House, we emphasize the importance of defining your role identity early on BDSM journey. Understanding whether you identify more with K9, K8, or other common BDSM archetypes (like Dom, Sub, Mistress, Master, etc.) is the first step to finding the book that best fits your preferences and interests.
