Once in the hands of the Trust's special care unit, the horse's condition was slow to improve. Concerned that a sudden increase in her calorie intake might prove fatal, staff limited her food until they were sure her body could handle it. Meanwhile, she was also kept in isolation on the sanctuary, deemed far too weak and traumatized to interact with the rest of the herd.
"Every time it looked like Polly was making progress there was another setback," the Horse Trust wrote on its website. "Her temperature, pulse and respiration rates were abnormal and her weight refused to stabilise, every time she gained a Kg it was lost within days. Rain scald and dermatitis were minor issues for Polly to contend with."
But the sanctuary staff never gave up, and they say Polly proved to be a fighter too.
