Abstract: A male dog diaper of the present invention is specifically adapted for the male dog or 4 legged animal anatomy. The diaper includes a moisture barrier, a liner bonded to the moisture barrier, and an absorbent assembly sandwiched therebetween. The moisture barrier is gathered along each of its longitude sides edges between terminal points. The moisture barrier is gathered along its elasticized sides. A male dog diaper is disposable. In addition, the diaper is for removable emplacement and securement circumferentially about a dog's rear torso and his inguinal region. A lower body sheet and upper body “Male Dog Diaper”, together with Velcro™ like stretch tabs, allow such wrap-around emplacement and securement without slipping, gathering or “bunching up”, and, together with removable engagement via the Velcro™ like stretch tabs, maximum comfort is afforded the dog. Highly absorbent material fixedly carried by the body sheet absorbs and retains body fluids, such as urine, discharged by the dog.
