MADRID (AP) — Dog owners in Madrid beware: Pick up after your pooch or face working as a street cleaner.

Madrid Mayor Manuela Carmena is warning dog owners they'll face stiff fines or possibly weekend work as street cleaners if they are caught in an upcoming dog poop crackdown. Carmena says Monday that police will initially focus on two city districts where many dog owners are not cleaning up after their pets.

Dog owners could be fined up to 1,500 euros ($1,700) if caught. Carmena also says she'll propose to city councilors that offenders perform street cleaning assignments on Saturdays or Sundays as a possible substitute for the fines.
