The "sick" and "senseless" death of a dog dragged at least 4km behind a vehicle has horrified a motorist who tried to save the animal.
Gabrielle Crosby was driving near Masterton on Sunday afternoon when she saw a white ute travelling in the opposite direction pulling a dog by a long lead. She made an immediate u-turn and followed.
"I honked my horn. I flashed my lights. I started screaming but they didn't stop. It was a nightmare," she said. "I don't know how long the dog was out of the ute for. I followed them for about 4 or 5km. The dog was trying to run to keep up, but it was being dragged."
A farmer driving a tractor along the road also tried to alert the ute's driver, but to no avail, Mrs Crosby said.
She caught up with the ute near sewage ponds at Homebush.
