DOGS worrying or harming livestock could be destroyed if caught.
The message comes from police after two sheep were killed and a lamb orphaned following three separate attacks on the same farm.
As reported in the Surrey Mirror last week, Rachel McMaster's sheep farm in Walton on the Hill has suffered three dog attacks in two months.
PC Stephen Pearman, who is investigating the incidents, said: "It is totally unacceptable for dogs to attack and maul livestock and for their owners to allow them to be so dangerously out of control."
He added: "This is not just upsetting for the farmer, but has cost them financially.
"Most dog owners don't realise their pet could be destroyed if the dog is found worrying livestock and I stress the importance of keeping your dog under control when near people and animals."
Police said a number of owners have already been spoken to in the area about the consequences of allowing dogs to behave in a manner which would scare or harm livestock.
The latest attack, which happened on April 15, led to the death of a sheep, orphaning a lamb. Miss McMaster, 21, said: "She will recover but not without me. I have to take on the role of mother.
"This will impact severely on its growth, not having its mother, because mother's milk is best. We can only supply the lamb with milk four or five times a day while if it was with mum it would have her milk every hour."
The first attack, on February 13, left four animals with injuries. The second, on April 11, resulted in one ewe being killed and two injured.
As her business is still in its infancy, Miss McMaster is concerned about the financial impact of the attacks.
February's incident cost her £3,000 and she estimates the overall cost of all three attacks will rise to about £5,000 once vet bills and medicine costs are factored in.
