Scotlund Haisley, the founder and president of Animal Rescue Corps, has spent more than twenty-five years saving the lives of thousands of animals. Wearing a respirator mask for protection from the piercing ammonia that hangs in the air and with law enforcement officials at his side, he infiltrates puppy mills, animal fighting operations, and other large-scale cases of animal cruelty, freeing dogs, cats, horses, and other animals from a life of wire cages, filth, and starvation—and sending them on their way to loving, protective caregivers. Filled with dramatic rescues, Compassion in Action is a gripping ride through the underworld of those who profit from the enslavement of animals. From dogs trained for fighting to emaciated horses to animals stranded during natural disasters, the author and his team save animals from heartbreaking conditions, changing attitudes—and laws—along the way. It is a story of hope for the most vulnerable among us.
