"No go" areas for dogs in Sutherland Shire are identified in a new interactive map.
Sutherland Shire Council produced the map, which is described as "a quick and easy guide to where you can and can't take your dog".
A council spokeswoman said residents and visitors had more than 1700 kilometres of footpath and hundreds of parks where dogs could be walked on a leash.
There were also six off-leash areas, including three dog-friendly beaches.
"However, there are some areas, such as Woolooware Bay shared pathway, dogs are not allowed to visit, even on a lead, due to safety and environmental risks," she said.
"Sutherland Shire is home to many threatened species, including shorebirds birds like the Pied Oystercatcher, Eastern Curlew and Little Terns.
"Some shorebirds are migratory and are highly sensitive to disturbance from the sight of dogs, boats and humans and if disturbed may not have the strength and energy for the long return flight to places as far away as Siberia and Western Alaska.
"Other shorebirds nest here in the Sutherland Shire on low sand dunes and beaches where they are vulnerable to trampling and disturbance."
Other environmentally sensitive areas, where dogs are not permitted, include Wanda Heritage Dunes, Taren Point Shorebird Reserve, Swallow Rock Reserve, Grays Point, Maianbar Foreshore Reserves, Bonna Point Reserve, Kurnell and Joseph Banks Native Plant Reserve, Kareela.
"Dogs are also prohibited from being within 10 metres of any children's playground and play equipment, within 10 metres of food outlets unless they are in a public thoroughfare such as a road, footpath or pathway, swimming baths and most of our beaches, childcare centres and shopping centres," the spokeswoman said.
"Dogs must always be on a leash and under effective control by their owner when in public places including parks, sports fields and bushland areas, unless signage indicates it is a dog off-leash area.
"This means you must be able to hold the dog without it pulling away from you, prevent it from rushing at people or other animals, and the dog must obey simple commands.
"To ensure Sutherland Shire remains clean and tidy for other users, please also place your dog's poo in bins provided or take it home and dispose of it."
Mayor Carmelo Pesce said, "It's important to know where you can and can't take your dogs in order to be a responsible pet owner, to be considerate of others and to help protect our natural environment".
