Roaming dogs have plagued the Raetihi area over the past six months and killed sheep.
Now the Ruapehu District Council wants Raetihi residents and the farming community to report any roaming dogs they see.
Council compliance team leader Brenda Ralph said council staff had been called out to a number of horrific attacks where sheep had been killed or had to be put down because of their injuries.
Mrs Ralph is asking residents to advise the council of any roaming dogs, or if their stock has been attacked, even if they didn't see the dogs involved.
"Once dogs start this behaviour, they will keep doing it until they are caught."
