The horse was found with her legs tied together by a horrified member of the public at a field gateway in Beaconsfield, Buckinghamshire.
The RSPCA has launched an investigation and has hit out at those who dumped the horse “as if they were rubbish”.
It is very upsetting for everyone involved when animal bodies are dumped so callously like this as if they were rubbish,” said Inspector Jaime Godfrey, who is investigating for the animal welfare charity.
She was not microchipped so we don’t know where she has come from, or who did this to her, so we’re appealing to the public to share any information they may have about how she died and and who dumped her.
About 90 horses a month are rescued by the charity from neglect and suffering across England and Wales.
