Auckland Council's putting the hard word on unregistered dog owners.

The council is set to issue 5500 infringement notices over the next few days to dog owners who've failed to properly register their pets.

The council's general manager of compliance, Robert Irvine, says there will be a grace period - and people have the option to pay their registration fees to get their fines waived.

"If you're a responsible dog owner, we give you a discount - and there's also the early discount."
