A terrier which was one of two dogs dumped at a waste management site in Cambridgeshire was so emaciated she had to be put down, the RSPCA said, after appealing for witnesses to find the person who dumped them.

A female black and white terrier, now named Eva, was emaciated and suffering from extreme dehydration.

She was taken straight to a vet who said that her condition was so poor she had to be put to sleep to end further suffering.

Her companion, a chocolate Cocker spaniel now named Charles, was a lot healthier and bright, but distressed at being abandoned.

RSPCA inspector Richard Lythgoe said: “Poor Eva was in a terrible state when she was found.

“She was so weak she could barely lift her head. All she could do was blink really.

“The vets did all they could to save her but sadly she did not respond to any treatment. It seems she must have been neglected for some time.

“Charles was in a better state of health, but had still been left without care to wander around alone in a hazardous spot. Who knows what would have happened to him had they not been found.”

They dogs were both discovered by a member of the public at Ely Road waste management site in Waterbeach on Monday September 14.

Insp Lythgoe urged anyone with any information about where these dogs may have come from, or why they were dumped in this way, to call the RSPCA in strictest confidence, on 0300 123 8018.
