The most striking thing about the horse was her eyes. The light seemed to have gone out from them. Like the horse had just given up.
That's when another kind of light flicked on inside Lewis.
"I knew she was the one," she recalls.
Make no mistake: This was no show horse. Before arriving at the shelter, her sole function in life was to breed. In fact, her previous owner had started breeding her from such a young age, the horse lost her first baby - an outcome that sparked her owner's wrath.
"He beat her and starved her, and kept her locked in a small pen," Lewis says.
At last, the horse's old owner agreed to give the horse to a member of his family, who, in turn, brought the battered horse to the shelter.
And along came Lewis.
"I called my husband and told him I wanted her," she says.
Lewis had no idea if this horse was too shattered to ride. Or if she would even live much longer.
"All I knew was she deserves a chance to be a horse," she explains.
