Canberra's dog owners have been put on notice that the rules around where you can and can not walk your pet are changing.

The ACT Government has released the first update to the Territory's dog exercise maps since 2005.

The changes will come into force from Monday, January 11.

Minister for Municipal Services Shane Rattenbury said all cycle paths and footpaths were on-leash areas under the new rules.

Sports grounds were conditional zones where people could let their dog off the leash as long as there was no organised sport taking place.

Weston Park and Nara Park have also changed from dog prohibited parks to on-leash areas.

But Mr Rattenbury said dogs would be banned from playgrounds and barbecue areas.

"One of the key aims here is to have consistency across the city so it's easy for people to know where they can take their dogs, when they can take them there and what the general rules are," he said.

"Canberra has been rated as Australia's most dog-friendly city and we believe that these changes to the maps will further clarify that and continually allow people to take their dogs to all sorts of places."

Mr Rattenbury said the old maps were inconsistent in parts and required updating due to growth in Canberra and improvements in mapping technology.

He said owners would risk a $150 fine for breaking the new rules.

"The rangers will generally take an educational approach of reminding people what the rules are, particularly in this early phase where there's some changes coming in," Mr Rattenbury said.

"We want to work cooperatively with the community and allow people to have dogs in this city, dogs are great companions, but at the same time remind owners that they do have responsibilities."

He said signage would go up to alert people to the changes over the coming weeks.
