Four counties did not issue any fines in the past 12 months.
It’s claimed a lack of dog wardens is to blame for the high number of dog attacks that go unpunished.
It’s estimated there is roughly one dog warden for every 3,000 dogs in Ireland.
1,500 dog attacks have been reported to Gardaí in the last two years.
Four counties have not issued any fines in the last year, while three handed out only one, according to the Irish Independent.
Sinn Fein Senator Lynn Boylan says the level of enforcement is hit-and-miss.
“No dog warden has the capacity to police that number of dogs, so there is an issue around the number of dog wardens,” she said.
“It is welcome that as the government has announced that they’re going to up the numbers of dog wardens, but that’s not the only problem because there’s huge disparity across the different local authorities around enforcement of the Control of Dogs Act,” she added.
