Teachers are used to waging a never-ending war on litter. But two heads in Wales have taken action against dog mess piling up outside their schools.
Roads leading to Ysgol Pendorlan, a primary, and Ysgol Glan-y-Mor, a secondary, in Colwyn Bay are covered with the mess left by dogs and the heads say that it is an environmental hazard and a nuisance.
Mike Mulvaney, head of Ysgol Pendorlan, has had to hose the pavement before pupils arrive at school. "We are forever having to call environmental health and the dog warden," he says.
"It is a health hazard when the offender lets the dog go outside entrances and it gets trawled into the yard and school."
Doreen James, headteacher of Ysgol Glan-y-Mor, has raised the issue with the school's board of governors and the area's dog warden, who has warned local dog walkers that he is being extra vigilant.
