Dog owners who allow their dogs to foul in the street without cleaning up after them will be fined up to £200 in Ards and North Down Borough under new rules introduced by the council.
And they will face another similar fine if they are found to have their dog off lead in designated areas where the council has ruled dogs should be walked on leads only.
Ards and North Down Council have ramped up their fines for general littering, dog fouling and failing to leash a dog, with new penalties reaching two and a half times the current penalty.
