Residents who have not yet re-registered their dogs are being urged to do so through the Council's website.
With only 25 percent of dogs re-registered so far, the Council is warning there could be long queues at the Council's offices as owners of the remaining 5,000 dogs look to re-register before the end of July deadline.
Customer services manager Joe van Noord says residents who leave registration until the last minute risk ending up in long queues.
"This is an issue every year and while we always look to provide great customer service, this is difficult with so many people coming in during the last week," he said.
Mr van Noord says re-registering dogs through the Council's website is the best option.
"All dog owners need to re-register online is the information from their re-registration form and a credit card and they can avoid the rush," says Mr van Noord.
Council Environmental Monitoring Manager Rick Catchpowle is also urging dog owners to register as soon as possible.
"Registration packs were sent out to dog owners in June which advised of the 1 August deadline," he said.
Mr Catchpowle says dog registration is not only required by law, it is also in the best interest of your pet.
"The registration information about your dog goes onto a national register which helps us to reunite owners with their dogs and to identify owners in the case of wandering dogs." he said.
Mr Catchpowle says late registrations can be costly.
"After 1 August, a 50 percent late payment fee will be charged on top of the registration fee," he said.
Failure to register a dog can also result in dogs being seized, an infringement fine of $300 or prosecution.
