It seems as though the Council have taken notice...
From the "Nottingham Post" - I've taken the liberty of removing names & addresses from the article prior to posting here -
"TWO dogs had to be rescued after falling down a 20-foot hole in a park on the edge of Nottingham.
Rosie, a one-year-old Staffordshire bull terrier, and Benji, a nine-year-old parson russell terrier, had to be winched up by firefighters to escape from the shaft.
Firefighters said the hole kept filling with water and described it as "very dangerous".
Now the dogs' owner ... fears the hole in Broxtowe County Park is going to cause further, more serious accidents.
"What if it was a child that had fallen down there?" she said. "The hole itself has been there for years, but over time it must have opened up and now it's the size of a living room.
"The council need to sort it out. It's a country park – there's so many children from Broxtowe Estate going there that there's a very big danger the same thing will happen to them."
Mrs ... dogs were being walked by her son ... at around 5.30pm on Wednesday when they fell down the hole close to Nottingham Road, which leads all the way up to the park.
When the dogs fell down the hole he ran back to Mrs ... house, where they rang the fire brigade.
Crews from Stockhill Fire Station attended the incident and plucked the dogs from the water at the bottom of the hole.
Mrs ... said her dogs are now at home recovering from their ordeal.
"I was absolutely terrified," she said. "I was devastated and just begging the firemen to save my dogs.
"I can't even describe the feeling when I saw a fireman walking towards me with them. It was just so emotional.
"I can't thank the firemen enough – they were absolute heroes."
Once the dogs were safe firefighters put a cordon around the area. Martin Grace, watch manager on the green watch at Stockhill Fire Station, said they had made it as safe as possible before handing it over to Nottingham City Council, which is responsible for the upkeep of the park.
"It was quite a difficult rescue because of the constant water that was filling into the shaft, and the time of day meant it was dark," he said. "The hole was about eight foot in diameter and between 15 and 20 foot deep. It's very dangerous, I wouldn't like to fall down there.
"It looks like it was a definite excavation, it wasn't subsidence. The dogs had got off the leads and been running in the woods and just fell down it."
Eddie Curry, head of parks and open spaces at Nottingham City Council, said: "We have fenced off the area and will be carrying out more investigative work to find out what has caused the hole to open up in this way and to make sure it is secure and safe for the future."
