A Watchdog's Tale (Traditional Chinese: 老友狗狗, literally Friends of Dogs), is a 2010 TVB modern drama series.

It stars Linda Chung and Steven Ma as the main leads, with Kent Cheng, Natalie Tong, Raymond Wong and Maggie Shiu as the major supporting cast.

Sing's wife died a long time ago, but left him with an obedient daughter, Lai Sin Yue (Linda Chung).

Chow Yung Kung (Steven Ma) is the renovator who is in charge of preparing the dog care center.

The two side stories involve Chiang Tin-Ngo (Maggie Shiu), her brother Tin-Hung (Joseph Lee), Chou Ka-Man (Natalie Tong), and Ho Tin-Yau (Raymond Wong Ho-yin).

Tin-Hung, scared that his sister might figure out the kidnapper was him, moves himself to the countryside too, attempting to prevent Tin-Ngo from getting any serious evidence.

Unknown to her, Ka-Man has been hauling around a bowling ball stuffed with crystal meth that she thinks is a present from her dad... Will Sing learn to accept Kung and Yue?
