Connie was at death's door when officers from the Royal Society for the Prevention of Cruelty to Animals (RSPCA) stepped in.
"Despite her awful state she seemed fairly bright, but her eyes had a sadness to them," Kate Wright, the RSPCA officer who adopted Connie, told The Daily Mirror. "I wonder now if she was fearful that her unborn foal would be suffering.
"It seems I rescued two horses that day." England is seeing the number of abandoned horses surge, according to the RSPCA, with nearly 70,000 calls about the animals in the past three years. Among them, 1,900 were abandonments - a consequence, the organization says, of the increasing cost of keeping a horse.
