An investigation been launched after five cygnets were reportedly killed in a dog attack.

The cygnets were apparently found dead at Kearsney Abbey yesterday and both Kent Police and Dover District Council have been told.

A Dover District Council spokesman said today: "We were shocked and disappointed to hear of this incident involving what is understood to be a dog/dogs in Kearsney Abbey yesterday.

"We have reported the matter to Kent Police. We would remind dog owners that Kearsney Abbey is subject to a Public Spaces Protection Order and would stress that dogs must be kept on a lead on the café side of the Abbey."

The cygnets are thought to have been born to the same pair of swans at the Temple Ewell park.

PSPOs in general can be used to have dogs kept on leads and banned from specified areas.

The horrific news has spread across the Home Counties with a Surrey-based swan welfare group commenting on its Facebook page.

The Swan Sanctuary's post said: "We were saddened to learn that Kearsney Abbey near Dover have lost all of their cygnets to a suspected dog attack.

"We would like to remind all dog owners that at this time of year it is especially important to keep your dog on its lead.

"Most of us here at the Sanctuary are dog owners and know how dogs love to run free but near wildlife not only endangers the wildlife but also the dogs too."

A spokesman for the RSPCA said: "This would have been very distressing for people to witness, and the message here is clear - please keep your dog on a lead when you know you are near wildlife.

"Remember that a wild animal may be nearby, but not instantly obvious, so make sure you stay vigilant.

“Legally dog owners should have charge and control of their animals in a public place. We would urge dog owners to act responsibly to ensure sad incidents such as this are prevented."

The RSPCA advises anyone who finds cygnets in need of help to call the RSPCA’s emergency line on 0300 1234 999, for further advice.
