Douglas arrived home to find his dog dead in his backyard and told the Herald he has not had a response from police.
A police spokesperson said police and the Armed Offenders Squad carried out a search warrant at a Moutere Highway property looking for a male wanted by Police for violent offences who is believed to have access to firearms.
"While at the property, two dogs were secured by Police. As another building was being cleared, a large dog emerged and attacked a Police dog."
Police said the attacking dog was shot dead to protect the safety of Police officers and their dogs.
The police dog was not hurt and the wanted man has still not been located.
"Police work in a high risk environment and on occasion our staff do need to use tactical options such as a firearm to keep the community and themselves safe.
"It is a rare occurrence for Police to shoot an animal, however on occasions it does happen. The decision to use a firearm is never taken lightly by frontline staff, who must make quick decisions in dynamic and ever-changing situations."
