British police dog handlers are having to learn some Dutch commands to deal with imported dogs:

LONDON (Reuters) – Police dog handlers are having to take language classes — to communicate with their latest recruits.
Finding it increasingly hard to find suitable German Shepherds in Britain, some police forces are bringing in dogs from continental Europe.
But there’s a problem.
Although the latest arrivals possess all the attributes needed for police work, they only respond to commands in their native language.
Dog handlers at Avon and Somerset police for example,
which has recruited three dogs from the Netherlands, have been given a sheet of practical commands in Dutch.
