Children took part in a peaceful protest to show they were not messing around with a new campaign.
Pupils at King Edwards Primary School joined North Tyneside Council in launching a new campaign aiming to tackle dog fouling.
The borough-wide ‘NO MESSING!’ initiative will use engagement, enforcement and education.
Council mascot ‘Waldo the Wonderdog’ joined Mayor Norma Redfearn, Coun John Harrison and pupils in a demonstration through the streets by their school.
Mrs Redfearn said: “I must thank the majority of dog walkers who are conscientious, but a message must be sent to those who choose to break the law in this way that it simply won’t be tolerated.
“I would also thank children from across the borough who designed fantastic posters to support the campaign.”
King Edward Primary was chosen to launch the campaign after Year 5 pupil Sophie Appleton won a borough-wide competition to create a poster encouraging people to pick up after their pets.
The pupils marched holding placards showcasing Sophie’s design, while it will appear on leaflets, posters and lamppost stickers.
Coun Harrison said: “Not just unpleasant, dog fouling can cause serious health problems, particularly to young people, and owners must take responsibility for their pets.
“With 500 dog waste bins strategically placed throughout the borough and along popular dog walking routes, they really have no excuse.
“We will be taking a much stricter approach to issuing the fixed-penalty notices and prosecuting those who do not change their ways.”
Patrols will be increased across the borough and £50 fines issued to anyone seen failing to pick up after their pets.
Environmental wardens will also be on hand at different locations to offer advice on responsible dog ownership, as well giving out free dog mess bags.
