Dog owners who do not clean up after their pets will now be fined £75, a rise of £25.
The City Council is cracking down on environmental crime and councillors say they're responding to pleas from residents to get tough with anti-social behaviour.
“Hard working families across the city tell me they are sick of paying the cost of crimes caused by the minority who don't play by the rules, which is why I am calling time on the people who ruin our neighbourhoods for the rest of us."
The new £75 fixed penalty notice on littering will be introduced from June 1 and the £75 dog fouling notice will be implemented soon.
