Work to improve the water quality and remove weed matter in dams Strathdale's Harcourt Dog Park is expected to help reduce the chance of blue-green algae.
The City of Greater Bendigo allocated $40,000 for the works, which started after Easter and were completed this week.
Council's manager of parks and open spaces Paul Gangell said the works also made the dams and parks more enjoyable for the dogs.
The dams now feature stone-based entry points for the dogs.
"Removing the silt and vegetation matter that choked up the dams will help with blue-green algae and the water quality, which makes it far more enjoyable for dogs," he said.
"Our team leader for natural reserves put those (new entries) in to stop erosion of the dam but give safer access for the dogs."
The three-month project has seen a part of Crook Street park fenced off.
Mr Gangell said fences will remain in place as newly planted vegetation and grass takes hold.
"It will be there until the plants establish, that's the aim," he said. "The fencing will the the re-vegetation of the embankment a chance and we have more plants to go in over the winter.
"We have had a some really positive feedback from the community about the improvements as well as other ideas that people would like to see happen at the reserve."
More work is expected to be completed at Crook Street's Harcourt Dog Park as well as the dog park in California Gully's Truscott Reserve and the Kangaroo Flat dog park in Allingham Street.
"For summer we will have drinking fountains in park for humans, but they will also give dogs access to fresh water, which is not available in the (Crook Street) park," Mr Gangell said.
"Further funds are allocated for Kangaroo Flat and California Gully parks. There are outstanding works at both those reserves that we hope to have completed by Christmas."
Mr Gangell said it was encouraging to see all three dog parks so well used by pet owners.
"It's fair to say (the dog parks) are getting more use than other traditional reserves (in the city)," he said.
"It's incredible to see. I have managed open spaces for long time and usually putting fences around a reserve restricts people," he said.
"In this case it has encouraged people to use reserves that were otherwise under-utilised."
