In the last month three lambs have been killed in the Tandridge area.
Surrey police are urging people to identify whoever is responsible for the deaths.
The lambs all had visible teeth marks from a dog and had been cut by a knife.
They were killed on three separate occasions, twice in a field in Tandridge Lane between 3.30pm on the 31st of July and 10am on August the first; and between 7pm on the 6th of July and 12.41pm on July 7th.
The third instance was at a field in Moor Lane, Edenbridge at 11.15am on July 9th.
The investigating officer PC Alice Bennett says that they appear to be deliberate attacks and are incredibly upsetting for the farmers.
