A pregnant Highland cow known as “Gladis” and her unborn calf have died after being attacked by dogs in Dorset.

Owned by Redlands Coppice farm, she had been grazing on National Trust land at Eggardon Hill near Bridport when she was attacked on Wednesday evening.

Farmer, Cameron Farquharson, said Gladis, who died after falling over a 30ft (9m) embankment, had been “chased to her death”.

He urged dog owners to use common sense and keep their pets on leads.

National Trust tenant, Mr Farquharson said he was “devastated – she was due at anytime.” He added had the owners of the dogs reported the attack, “we might have been able to save her and her unborn calf”.

“We are begging people to please, please, please adhere to the notice on the gate and keep your dogs on a lead.”

A National Trust spokeswoman said: “We ask that people keep their dogs on leads around livestock and help us avoid livestock being hurt unnecessarily whilst they are doing an important job of keeping the Dorset countryside a beautiful conservation area.”

Since announcing her death on Facebook, the farm said it had been inundated with hundreds of “kind comments” about Gladis.

Mr Farquharson also confirmed Dorset Police were investigating the attack.
