Today is the last day for dog registrations before penalties apply. However, Ashburton District Council is implementing a grace period whereby payments received before 5pm, Monday 4 August will not incur penalties.
There are over 7,000 dogs in the district and so far around 2,000 have yet to be re-registered.
Mr Catchpowle says late registrations can be costly.
"A 50 percent late payment fee will be charged on top of the registration fee for late registrations," he said.
Failure to register a dog can also result in dogs being seized, an infringement fine of $300 or prosecution.
Environmental Monitoring Manager Rick Catchpowle says "We urge residents to re-register their dog online before Monday,"
Currently any new dogs or changes to contact information and other details would have to be completed at the Ashburton District Council office.
"If you have changed address, your dog has changed ownership or died, please let us know as soon as possible," he said.
