It’s not fun spotting fresh doggie doo-doo – or worse, stepping in it – and one French town is cracking down on badly-behaved dog owners with an unusual initiative. Béziers is trialling a DNA dog passport that uses a saliva sample to track an abandoned poo back to its owner. As part of a 2-year trial, owners will be fined €38 (A$62) if they are caught without a passport while taking their pet out for a walk in the city centre, and will be fined €122 (A$200) if found to be a fecal felon. It’s the second time the idea has been proposed in Béziers after a 2016 attempt failed after concerns it hampered residents’ freedoms. Spain, Italy and the UK have all used a similar method with success.
