COFFS Harbour City Council rangers issued 33 infringement notices to dog owners following a series of patrols last month.
Senior ranger Gordon Polkinghorne said the number was disappointing, with rangers finding people with unregistered dogs, owners failing to control their animals and animals in prohibited areas such as children's playgrounds.
Mr Polkinghorne said it had been 11 years since the Companion Animals Act came into force including hefty penalties, but the patrols showed many pet owners remained ignorant of their obligations.
These include lifetime registration and microchipping of dogs and cats. Dogs must be leashed in public except in leash-free areas.
A full list of leash free areas is available on council's website on www.coffsharbour.nsw.gov.au
