DOG attacks on postal workers across Ellesmere Port are rising - with owners being asked to control their pets.

Royal Mail and the Communication Workers Union (CWU) are appealing to residents to help reduce the number of incidents during the summer holidays.

The number of attacks in the CH postcode area – which comprises Flintshire as well as Chester, and Wirral – has risen by 24% since 2010.

A total of 36 took place from April 2011-April 2012, and the number traditionally rises during the six-week school break.

Mark Lawrenson, collections and delivery manager for Royal Mail in the CH postcode, said: “The number of attacks is unacceptably high.

“Clearly, most dogs are not inherently dangerous, however even the most placid animal can be prone to attack if it feels its territory is being threatened. Even just being threatened by an unrestrained pet is a frightening situation for our delivery staff, and we would appeal to owners to keep their pets under control.”

Royal Mail and the CWU are working together to raise awareness of dog attacks through targeted campaigns costing more than £100,000.

And 90,000 posting pegs have also been issued to help workers put envelopes and parcels through letterboxes while protecting their fingers.

Dave Joyce, CWU national health and safety officer, said: “The age-old image of the dog attacking the postman is not a laughing matter.

“Thousands of our members are bitten every year and hundreds suffer debilitating injuries.”
