Two greyhounds were left badly injured after they were attacked by two dogs on a morning walk in Dereham.

The greyhounds, Duke and Lucy, were on walk with their owner David Wheatley, 77, on Neatherd Moor at 10am on Saturday when they were suddenly attacked by two Staffordshire bull terrier type dogs.

Duke managed to slip his lead and run away but was chased by the dogs across the moor. His injuries required surgery and Lucy suffered puncture wounds and severe bruising.

Mr Wheatley's wife Sandra, 71, said that Duke has not been the same dog since the terrifying incident.

'He was taken straight to the vets where he was anesthetised to stitch up the wounds and he has been traumatised since,' she said. 'He paces up and down continually and won't sit still or sleep in his bed. He is quite a timid dog and this has really upset him.'

Norfolk Police confirmed they are investigating the incident and Mrs Wheatley hopes that the owners of the two dogs will contact them.

She said: 'I just wish that the owners of the dogs will come forward as they need to be aware that they possibly do it again. They need to be aware of the damage they have done and learn from it.'

•Anyone with any information of the incident should contact PC Metcalf at Dereham SNT on 101.
