You find yourself as a unwilling participant in an experiment in which your captors treat you like a dog. You are put into room and chained. They make you wear a collar at all times. If you are chained, you will wear a normal collar but if they let you go for a walk or you are a "bad dog", they will make you wear choke collar. Only interaction you get is with masked scientists wearing hazard suits. They make you eat dog food, sleep on the floor, wash you with cold water and treat you like a dog.
