A councillor has pleaded with owners to take more responsibility for their dogs.
Cllr Huw Williams, of Llanbedr Dyffryn Clwyd/Llangynhafal ward has been monitoring Moel Famau since Christmas where he has seen a “massive problem with dog muck”.
Cllr Williams said: “There’s a massive problem with dog muck by the car park. I’ve seen multiple bags with poo in them thrown into the heath effecting wildlife.
“We have hundreds of thousands of visitors to Moel Famau and I want more bins up there for people to dispose of their waste and make the area tidy.”
The councillor has spoken to Denbigshire Enforcement Team who have visited the site.
David Shiel, Countryside Officer with the Area of Outstanding Natural Beauty, said: “We see more than 30,000 visitors coming to Moel Famau alone in a year, with many people also exploring the scenic countryside in other parts of our Area of Outstanding Natural Beauty.
“We want people to enjoy their visits to the countryside, it is very much open to everyone. However, we are concerned about dogs being let off their leads, especially on Moel Famau but also on other countryside public footpaths across the county.
“We are concerned that dogs being allowed to roam free could increase the risk of injury to sheep, in particular around the lambing season.
The Clwydian Range is an outstanding landscape that so many people enjoy and love but we would just ask visitors to remember that a lot of it is farmland with grazing stock.
“Dog waste left in bags in the countryside is harmful to the environment. The waste is toxic and can spread disease to other animals and it doesn’t biodegrade in a plastic bag. We would ask all dog owners to please dispose of their dog waste responsibly either by using the bins provided or if there are no bins by taking it away with them and disposing of in a responsible manner.”
