The horse, which weighs around 600 kilograms, was found on its side before crews arrived around 11.30am on Saturday.
Firefighters worked alongside a local vet to ensure the animal was looked after and treated appropriately.
Specialist animal rescue equipment was used to lift it back to its feet.
The horse was moving freely again by 1.15pm.
Station Manager, Dave Bond said: “I’m really proud of our crews and the way they worked together with the vet and site owners to make sure the horse was properly cared for at all times.
“This was a sensitive and complex situation, but thankfully the horse is back to its feet and free from any significant injuries.”
