A miniature Shetland pony and a Clydesdale are undergoing extensive veterinary treatement after being shot in the eye.
The 8-year-old miniature Shetland/Falabella and the 16.1hh Clydesdale were both found with air pellet puncture wounds to their right eyes.
Both animals are in danger of losing their sight after the attack which occurred between 7.30pm on Friday 16 January and 12pm on Saturday 17 January Lodge Bottom Lane, Headley.
Surrey Police are appealing for witnesses.
Mole Valley Sergeant Peter Gunning-Stevenson said: “This was a deliberate and shocking act of animal cruelty.
“This incident has distressed the owners and the whole equestrian community in the area.”
Police are especially concerned as the attack comes only a few weeks after a bull was injured in Slough Lane.
Sergeant Gunning-Stevenson added: “At the moment we are not ruling out that the two incidents are connected which is why we need information from the community. I am urgently appealing to anyone with any information at all,”
Anyone with information should contact Surrey Police on 0845 125 2222 quoting reference MV/09/242.
