A four-year-old child suffered deep cuts to the face when a dog attacked them at the Waipukurau trolley derby.
The Central Hawke's Bay District Council is now asking the owner to come forward after the child required medical treatment due to the attack.
A council spokesperson said it was too early to determine whether there would be any charges or whether the dog would be destoyed.
"We are working to formally identify the dog and the owner."
Three dog attacks have so far been reported in Central Hawke's Bay this financial year.
