Doggie Let Me Out is a series of situations that you must uncover. Each stage is a room. Your dog is demanding your attention and blocking the doorway. Your goal is to find something that will distract the dog and get him to engage in the mystery item.
Finding the mystery item is a challenge unto itself because you have to go through a myriad of nooks, crevaces and containers to find all of the missing pieces, in order to move through the room correctly. Finding all of the individual items (ie. door knob, 4 digit code, drawer key, etc) will unlock new pieces to the room, eventually enabling you to find the chew toy, dog food or other hidden item to give to your dog.
