A pedigree sheep worth over ?3,000 has been 'put to sleep' by a vet after suffering what police describe as 'a savage attack' by a dog.

The animal - a pedigree Texel ewe - had won first reserve at the Royal Manx Agricultural Show in 2006, and was a prized possession of its owners, Alan and Alison Rothwell.

Police say the sheep was found in a distressed state, at about 10am today.

It had serious injuries to its face and mouth, and was unable to move.

The vet estimates the time of the attack as earlier today.

Police say the ewe had two lambs which were apparently unhurt, although it might have received the injuries trying to defend them.

Based on the nature and extent of the injuries, the vet says the dog would either have been a large one, or one with powerful jaws.

It would undoubtedly have had blood around its mouth after the attack, which means the owner will probably be aware something has happened.

Police are urging the dog owner to come forward.

Anybody with information about the incident is asked to ring Police Headquarters on 631212, or the anonymous Crimestoppers line on 0800 555 111.
