They can sense survivors under rubble three metres deep, warn our soldiers of an approaching enemy and show sappers where to look for a mine. And they are also cute. Service dogs and dog handlers saved us even before Russia's full-scale invasion, but after 24 February, the threats and challenges increased. The film is about how dogs and military, rescue and rescue dog handlers cooperate and coexist, how they meet each other, build trust and mutual love, learn responsibility and save lives at the risk of their own.
