Your name is Sam Smith, you are 27 and single, moderately handsome and very athletic. You are (currently) male and have no immediate family as you where orphaned as a child. You work as a fitness instructor and visit the gym on a daily basis, for personal use alongside work. (Note: Sam Smith's only good friend went missing 6 months ago in the grand opening of the zoo. Police never found any clues as to where he went.)
You enter the zoo, a grand gate before you. You have a day off so you wander around for a while. Absent mindedly you walk into an empty viewing area for dogs from all over the world. You are about to leave when someone grabs you from behind and drags you off into an employee room that looks more like a lab. You look around and see bubbling phials and tubes of colourful liquid everywhere, unsure of their purpose. You take one last glimpse before you fall unconscious to a blow to the head... Your last memory was of a caged "dog" (It looked more like somewhere in between a baby and a hyena) and a concealed human(oid) holding a syringe.
