The creature was mauled by dogs who entered a paddock off Spring Bank Road in Conisbrough, Doncaster, on Thursday, December 10.
CCTV footage shows the three dogs walk into the paddock through a hedge late that evening, while torchlight can also be seen in the distance.
The pony's owners reported hearing dogs barking but did not realise something had happened until the following morning when they brought the pony in from the paddock and discovered several deep wounds to its rear legs and neck.
Sadly, the pony had to be put-down as a result of its injuries.
Due to the poor quality of the CCTV footage, the dogs owners have not been identified and officers at South Yorkshire Police are now appealing for anyone who might know them to come forward.
Anyone with information is urged to contact the force.
