K9 Cop(2016)

K9 Cop is a Hong Kong police drama following Lai Yat-tsau, a quick-tempered officer burdened by family tragedy. After his mother's death and father's descent into drug addiction, Yat-tsau raised his three younger sisters alone, hardening into a chauvinistic man. His superiors at Kwun Tong Police Station reassign him to the K-9 unit, hoping strict dog-training protocols will reform his character. There, Yat-tsau partners with veterinarian Ma Chi-ho, and together they investigate cases using police dogs. The partnership challenges Yat-tsau's rigid worldview as he learns discipline and compassion through his work with animals and his growing bond with Chi-ho. The series balances procedural crime-solving with character redemption, exploring how trauma shapes us and how unexpected relationships can transform us.
