A person who has not paid a dog fouling charge in four years is just one of 39 outstanding dog fines in Dundee.
Dundee City Council issued 1,265 on-the-spot fines on the public for offences like littering and fly-tipping between April 2011 and March 2014.
The most common penalty imposed was for littering, with 713 over the three-year period, followed by 222 for smoking in illegal places, 146 for dog fouling, 142 for fly-tipping and a further 42 for excessive noise.
Fines for littering and fly-tipping have reduced by 67% and 65% respectively but the number for dog fouling more than doubled.
A total of 43 fines have still not been paid, 39 of those being for dog fouling. One dog fouling fine even dates back to the financial year of 2011/12.
Andrew Llanwarne, co-ordinator of Friends of the Earth Tayside, said although on-the-spot fines for littering and fly-tipping were going down, they were still big issues.
He said: “The figures could actually mean there are fewer resources to catch people in the act of littering or fly-tipping.
“Currently, in the part of town that I live in the east of Dundee there is still an awful lot of littering going on. There are fewer bins than there used to be and problem areas are at bus stops, playparks and around fast food outlets.
“It may well be a small minority of people who are doing it, but it is still a large number of fines overall.”
A Dundee City Council spokeswoman said: “We have been encouraged by the positive response the Take Pride in Your City campaign has had on the Dundee public and the council will continue to pursue people who have not paid their fines.”
