Dog wardens and police officers are to undertake after-dark patrols at dog-fouling hotspots in Ribble Valley.
They are to blitz Clitheroe, Whalley, Mellor, Sabden and Read on the lookout for dog owners who let their pets foul public places, particularly at night.
They will be stopping dog walkers and asking them if they are carrying dog poop bags. And anyone caught allowing a dog to foul in public will be hit with a fixed penalty of £50.
The borough council’s head of environmental health, James Russell, said: “We recognise that the majority of dog owners behave responsibly, but a minority refuse to do so and are inconsiderate to the community. These people need to change their couldn’t-care-less attitude and join with everyone else who is helping to look after Ribble Valley.
“We will be making an example of those who persist in allowing their pets to foul in playing fields, public parks and footpaths, particularly after dark. I would encourage everyone to report offenders and help us make a difference.”
