A fresh appeal for witnesses to a dog attack in Harpenden has been made by police.

Between 2.05pm and 2.15pm on Sunday, a woman was walking her dog with her son along a footpath running parallel to Marquis Lane. Her pet was then attacked by four other dogs, which were being walked by a man and a woman.

Three bulldogs, that were not on leads, attacked the victim’s dog and, during the incident, a bull mastiff-type dog became free from its lead and also attacked.

The man and woman restrained the dogs and the victim and her son took their dog away.

The man walking the four dogs is described as having brown hair that was parted in the middle and wearing a green top and beige shorts. The woman is described as having long mousey brown hair and was wearing a green top.

Investigating officer PC Graham Paterson said: “This was a frightening incident for the victims and the dog - an Australian labradoodle called Rafiki - suffered multiple bite wounds, which required veterinary treatment.

“I am appealing for anyone who saw the incident or believes they know who the owners of the attacking dogs are to contact me.

“I’d also like to speak to two men who saw the victim, her son and dog, shortly after the incident and may have information that could assist the investigation.”

Anyone with information is asked to call the non-emergency number 101.
