Some police stations in China use geese instead of guard dogs to keep watch at night. Geese are very territorial and have better vision than humans.

Which guard dog provides the best protection? Maybe a Rottweiler, or perhaps a Doberman. Bullmastiffs are another one that would come to mind.

But if you asked police in rural parts of China's Xinjiang Province, they would tell you that the best guard dog isn’t a dog at all!

The police in these areas are using geese instead.

Yep, geese.

Geese are known for being very territorial and some defend their territory pretty aggressively. They also have very sensitive hearing and much better eyesight than humans. On top of all of that, they are loud when someone invades their territory.

So have these guard “dogs” been tested? Yes! Recently a man tried to break into a police station that used geese to recover his confiscated motorbike. The geese went crazy and woke up the sleeping officers.

Whether they would be good at defending by themselves doesn’t seem to be known yet, though.
