I wouldnt let them have her back.. ever. They could break her legs next for MORE money.
My Prince (also known as Phillip) was severely abused. As a weanling he was sold in the auctions, to various pony dealers, and one or more had really beat him up. From the time he was placed in the auctions as a weanling, to the time he was a 2 year old, men twisted his ears, had teenager sit on him and beat him.. they did horrible things to my lil Princey. Then he was rescued by my friend, Grace, and she broke him and raised him for 7 years before we bought him.
He's so terrified but I love him to death.
