A diaper and method for its manufacture are disclosed. The diaper comprises one gathered lengthwise edge with an elastic material for that edge to expand and contract. The other lengthwise edge is static in length and longer than the gathered edge. The disparity in length tapers the diaper toward the gathered edge. The diaper is secured around a male quadruped with the gathered edge being around the quadrupeds torso and the static edge fitting immediately anterior to its hind legs.
