Abstract: A kennel door which pivots about a vertical axis that bisects the door. The door is mounted within an opening in a frame. Disposed along the periphery of the frame are door seals which provide both a stop against which the door comes to rest and a seal against weather coming in through the opening when the door is in a closed position. When the door is in a closed position, the door seals are situated on diametrically opposite sides of the door such that they permit the door to rotate in one direction through the opening but not in the other direction. A spring biases the door in a closed position resting against the door seals.
