DNA used to track dirty dog owners

Officials in an Israeli city are using DNA analysis to track dog owners who allow their pets to foul the streets.

Authorities in Petah Tikva, near Tel Aviv, are setting up a special DNA database of local dogs.

There will be rewards for those who keep the streets tidy, but owners who fail to clean up after their pets could face fines.

Dr Tika Bar-On said that, at the moment, providing a DNA sample is up to individual dog owners.
