The sighting came as the Far North District Council prepared a crackdown on unregistered dogs.
Monitoring manager Barry Webb said allowing a dog to wander unsupervised in a public place was an offence under the council's animal control bylaw. Dogs deemed to be dangerous also had to be muzzled while off the leash.
Animal control officers would carry out a door-to-door check in the School Road area to see if anyone knew the dogs' owners. If located, they would be required to register the animals, if they were not already, and asked why they were not wearing collars or tags.
The owners would also be told the rules relating to dogs in kiwi zones.
Mr Webb said anyone living in an urban area needed a permit to keep more than two dogs per property.
The council was planning to check for unregistered dogs after the July-August dog registration period by visiting properties with previously registered dogs, and where dogs had been seen but not registered.
DOC and the council urged anyone who saw roaming dogs to call the council's dog ranger on 0800 920-029 or (09) 401-5200 from cell phones or outside the district.
