More than 20 pregnant sheep have died after “probably the worst livestock attack ever”, according to Kent state police.
Between Christmas Eve and 1pm on Boxing Day, 27 ewes pregnant with twins or triplets were attacked.
A Kent Police spokesman said he believed the attack was caused by a single dog, but said it “cannot rule out” the possibility that more dogs were involved.
Kent Police Rural Task Force PC Mark Pennicott said, “This is a tragic incident and possibly the worst livestock attack ever.
“The incident not only caused economic losses for the farmers, but also caused the animals to die unnecessarily.
“These dogs must have come home muddy and exhausted, and we promise to identify their owners.
“It is very important to find those responsible for these dogs as soon as possible, as the rest of the livestock are also left vulnerable to further attacks.”
Police said the attack took place on a field in Taingham near Sittingbourne and that barking was heard between 4 and 5 p.m. on Christmas Day.
