Tired of owners whose pit bulls attack humans, officials of Belo Horizonte, Brazil, have come up with a new idea: They are implanting microchips in the dogs in a voluntary program.

The chips, implanted at no charge, help identify the owner of errant or abandoned pit bulls, officials tell the newspaper O Globo. Already, more than 300 dogs have received the implants. Many more owners have expressed interest.

Officials say there is no harm to the dogs.
