K9 Cop (Chinese: 警犬巴打; Cantonese Yale: Gínghyún Bādá; literally "Police Dog Brother") is a 2016 Hong Kong police procedural romance comedy television drama created and produced by TVB, starring Bosco Wong, Linda Chung and Raymond Wong Ho-yin as the main leads, with Tracy Chu, Oscar Leung, Angel Chiang, Rebecca Chan, Jerry Ku and Kayi Cheung as the major supporting cast.

CID officer Lai Yat-tsau (Bosco Wong) parents died early, leaving him to take care of his three younger sisters.

Her husband Ma Chi-chung (Oscar Leung) works at the Agriculture, Fisheries and Conservation Department, but his attitude is very similar to his wife and often mooches off of his in-laws.

While recovering from a dog bit in the hospital he meets Ma Chi-ho (Linda Chung), who is more concern for Bah-da then Yat-tsau's injuries.

Her younger brother who also happens to coincidentally be Yat-tsau's brother-in-law Chi-chung works alongside her, but he too can't stand her because she made him feel stupid when they were growing up.

*(all names are homophone to the Cantonese translation of characters from Japanese Anime Captain Tsubasa) The main opening theme song "You Got Me" (你懂我) was sung by Linda Chung, composed by Dominic Chu and lyrics by Hayes Yeung.
