Complaints about dog poo are up more than a quarter in the Dublin City area in the last year.
City officials hope a new awareness campaign being launched today can persuade the "minority" of dog owners, who don't bother to pick up after their pets, to change their behaviour.
It will include loudspeakers playing a recorded warning in the city's worst dog fouling black spots.
Bernie Lillis, Dublin City Council's waste prevention officer said dog fouling impacts some of society's most vulnerable.
"People who are visually impaired and wheelchair users are all at risk," she said.
"Toddlers are stepping on the dog fouling and the parents go over the dog foul with their buggy and bring it into their lovely house."
Bernie Lillis said the campaign aims to reduce the issue in the city.
