Susan Shields, participated in the very first "Equine Comeback Challenge", put on by A Home For Every Horse. Susan was given a 12 year old paint horse named Mack. Susan had 60 days to train Mack as best she could, then she was going to put Mack through his paces at the "Comeback Challenge" competition during the 2014 Rocky Mountain Horse Expo, in Denver, CO. Susan was one of 10 horse-trainer combinations taking part.
The purpose of the Challenge was to showcase the abilities of horses found at rescues. Many people write off horses from rescues because they believe them to be damaged goods. The trainers were able to put to rest the idea that a rescue horse couldn't perform. Each horse made amazing progress in just 60 days, but none so much as Mack, he was 12 years old and hadn't yet been started under saddle. He and Susan won the competition in grand style and in this clip, Susan speaks about her experience with Mack.
