A woman has pleaded guilty to breaching a ban on horses and causing suffering to animals in her care.
Ms Fletcher, from Winchcombe, Gloucestershire, also admitted one count of breaching a disqualification order banning her from keeping horses.
The RSPCA was called in December 2013 to a DIY livery yard, where two thin colts were found.
RSPCA inspector Suzi Smith attended. She said: “The foal was very, very thin. The vet discovered he had a severe lung infection and was riddled with worms.
“I don’t think he would have survived the week if we hadn’t got the veterinary care he needed. He needed antibiotic injections twice a day and a great deal of TLC. Luckily, he pulled through and has gone from rags to riches as he’s been adopted by Olympic gold medallist Charlotte Dujardin, who has named him Santa.
“The other horse, a yearling called Frank, was also thin but has recovered well and we hope to find him a fantastic home.”
In October 2013, magistrates banned Lisa Fletcher from keeping horses for five years after she pleaded guilty to three offences of neglecting a grey Arab stallion.
Ms Fletcher had failed to explore the horse’s weight loss, breathing difficulties and overgrown hooves.
Sentencing has been adjourned until June 9.
