A car dashboard camera has filmed the moment police officers abandoned a dying dog by the side of a Queensland road, prompting an investigation by police and the RSPCA.

The video, filmed in Burpengary East on Saturday night, showed the officers dragging the injured dog to the side of the road.

The officers got into their patrol car and left, but not before they also hit a parked car.

Lily, a 10-year-old chocolate Labrador, was found by passer-by Bonny Martin the next day.

"I thought she had passed away so I was stopping looking for tags and that's when I noticed the breathing," Ms Martin said.

The beloved pet was paralysed and suffering hypothermia. She was rushed to a local RSPCA.

The clinic contacted Lily's owners, who had to make the heartbreaking decision to end their pet's life.

The RSPCA and Queensland Police have launched investigations into the incident.

"Officers and the driver of the vehicle believed the dog had stopped breathing and had passed away," police said in a statement today

"In hindsight, it is clear that the officers made an error of judgement."
