警犬 (jǐng quǎn): Police dog (Noun) — Meaning & Stroke Order

Police dogs work at the police station.

Without the assistance of the police dog, this search and rescue operation would likely have been much more difficult.

I saw a police dog in the park yesterday; it was training with its handler.

Well-trained police dogs can quickly track down suspects' traces in complex environments.

Despite the noisy environment, that police dog still accurately identified the suspicious scent.
