‘Xiǎo gǒu’ literally combines ‘xiǎo’ (small) and ‘gǒu’ (dog), forming a compound noun meaning ‘puppy’ or more generally ‘small dog’. It carries a warm, affectionate connotation—often used when referring to young, cute, or domesticated dogs, especially in informal speech or when speaking to children. Unlike the neutral term ‘gǒu’, ‘xiǎo gǒu’ implies endearment or familiarity, and is rarely used in formal or scientific contexts.

This word appears frequently in daily conversation, children’s stories, pet-related discussions, and social media posts about pets. It’s commonly modified by demonstratives (e.g., ‘zhè zhī xiǎo gǒu’ — this puppy) or adjectives (e.g., ‘kě’ài de xiǎo gǒu’ — cute puppy). While it can refer to any small dog regardless of age, it strongly evokes youth and playfulness, making it unsuitable for describing large or mature working dogs unless used playfully or ironically.
