Police and the SPCA are on the trail of a driver seen dragging a dog at speed down a Northland highway.
South African Werner Roos, who was holidaying in Rawene during Waitangi weekend, said he was driving on State Highway 12 near Waimamaku just after noon on Saturday when he saw a dog being dragged behind a car.
Senior Sergeant Brian Swann, of Mid North police, said officers were checking addresses in the area where the dog was last seen and narrowing down the people who could have been involved.
Mr Roos earlier said the dog, which appeared to be a light brown pitbull, was attached by its lead to the towbar of a silver SUV travelling about 60km/h.
The dog was on its stomach with its head in air and back legs dragging, leaving a trail of what looked like blood.
