The SPCA are seeking answers after a small dog was found abandoned at a SH1 rest area, tied to a rubbish bin.
It's not known how long the border terrier cross, Chewie, was left without shelter and apparently without food or water on Waikouaiti-Waitati Rd, near Seacliff.
"The dog is just left out in the open, exposed to all the elements, no way of getting away from anything that might happen to it," said inspector Sophia Tinirau.
If the dog's rescuer hadn't happened to pull into the "pretty remote" rest area, it's not clear what would have happened to her.
"If no one finds them, it's giving them a death sentence," Tinirau said.
