A Nelson man claims police shot his dog while searching the wrong house.
But police say they had a search warrant for his house and had no choice but to shoot it when it attacked a police dog on Friday.
Todd Douglas posted on social media at the weekend that his American pitbull Mud was shot in a "balls up" raid.
Douglas said he needed time to clear his head when contacted by the Herald today, but commented online that police were looking for someone next door when he and his partner were taken 1km away from their home so the search was carried out.
He alerted police about their three dogs, but they were left behind.
